What is Well-Being?

 

Well-being implies an evaluation. Being well is desirable and being unwell is undesirable. Most people are likely to prefer being well over being unwell. Thus, the meaning of well in well-being is uncontroversial. The crucial part of any definition of well-being is the "being" part of well-being. What is being? In other words, what is the object of the evaluation? I propose that well-being is an evaluation of an individual's life in its entirety. Thus, I define well-being as a positive evaluation of an individual's life. Like any other evaluation, the outcome of the evaluation process can vary along a single dimension from the most positive evaluation to the most negative evaluation . Although the term well-being implies a positive evaluation, I do not distinguish conceptually between well-being and ill-being. Well-being is the label for the positive pole of the full evaluative continuum.

 

One of the major problems of the concept of well-being is that an individual's life is a very complex object; as for example, compared to the taste of sugar as an object of evaluation. With evaluations of complex objects two problems arise. First, it is unclear how evaluations of more specific aspects of an individual's life should be integrated. Second, it is possible that the global evaluation of a life is not the same as a weighted sum of more specific aspects. These problems are illustrated by considering more specific aspects of well-being such as financial well-being. It is much easier to construct or recall examples of life's that illustrate specific well-being (e.g., financial well-being - Bill Gates) than to think of lives with high overall well-being (e.g., Does Bill Gates have higher well-being than the Dalai Lama?).

 

Thus, the main challenge for any definition of well-being is to specify criteria for the inclusion and exclusion of information that is required for the evaluation of entire lives. Given the complexity of the task, this is by no means a trivial question and it is possible that it remains impossible to define well-being. The construct of well-being may be to diffuse, subjective, and relative to defy a coherent definition. However, I believe that a coherent (internally consistent), universally applicable, and value-neutral definition of well-being is not only possible, but also necessary for a science of well-being. Without a definition that fulfills the aforementioned criteria, well-being research will be fraught with controversies based on the preexisting values of individual researchers and diverse measures of well-being.

 

It is notable that the social sciences have been conducting empirical research on well-being for 50 years. A keyword search in PsycInfo for "well being" in April 2008 retrieved over 25,000 references. One of the first references is to Sally's (1886) "The feelings: Nature of feeling." The abstract notes "Since the feelings are the elements of happiness and its opposite, the study of them is an important part of the science of well-being." (p. 1886). Given the long history of the construct of well-being in the social sciences, it seems improbable that the key concept of well-being that generated this research is still lacking. Yet, there are two reasons why well-being remains an unexamined and undefined construct in the social sciences. The first reason is that well-being is often used loosely to classify any study that implies an evaluation of a life. The studies do not claim that other evaluations are possible or that the measure used in their study is a perfectly valid measure of well-being. The more limited focus of these studies is evident in many titles that qualify well-being (e.g., "physical well-being, financial well-being, subjective well-being, psychological well-being). Any qualification implies that findings regarded to one type of well-being may not generalize to other types of well-being. Thus, qualifications serve the noble purpose of allowing alternative empirical programs of research to thrive. However, the problem of this pluralistic approach is that conflicting research findings are never resolved. Moreover, the main question of this article, namely how these various types of well-being relate to well-being per se is never examined. That is, how is physical well-being, financial well-being, or subjective well-being related to the evaluation of an individual's entire life? The second reason for the lack of a well-accepted definition of well-being is the failure to distinguish between different types of definitions. The purpose of this article is to provide a descriptive define the term well-being; that is, the aim is to elucidate the meaning of the term well-being. An important aspect of descriptive definitions is that they can be evaluated themselves: one descriptive definition can be superior to another descriptive definition. In contrast, stipulative definitions assign a new meaning to a term. Stipulative definitions cannot be evaluated because they make no claim to explain an already existing meaning of a term. For example, a stipulative definition of well-being may say that well-being is a life that maximizes life expectancy. As a result, well-being can be measured objectively in terms of the number of year's from an individual's birth to death. Although this definition is unlikely to be a good descriptive definition of well-being, it would be possible for researchers to use the existing term "well-being" and define it in terms of life expectancy. Stipulative definitions are unproblematic as long as everybody uses the term well-being with the new meaning in mind and does not confuse it with the alternative, unspecified existing meaning of the term. However, it is unreasonable to assume that people will clearly distinguish between two meanings of the same term, especially when one meaning is not explicated. Under these circumstances, it is likely that researchers and consumers of research findings will confuse the two meanings. In the present example, it would seem preferable to avoid the creation of a technical meaning of well-being and to label the measure of life years in a more descriptive manner as length of life or life expectancy.

 

Social scientists do not clearly distinguish between defining and stipulating definitions or explain whether their definitions are descriptive or stipulating. There are two reasons for this confusion. One reason is that lay concepts are often too vague to be scientifically useful. Many lay concepts may be defined in terms of prototypes or exemplars, and not in terms of a logical set of criteria. In this case, it may be necessary to create new stipulative definitions that are useful for the creation of empirical measures. To do so, a researcher may try to create a stipulative definition that retains as many of the essential aspects of the descriptive definition, but adds or eliminates some aspects of the descriptive definition to conform with requirements of scientific definitions. Different stipulative definitions can still be evaluated and compared to each other based on their ability to fulfill the two requirements of a good definition: the definition has to be descriptively accurate, and be scientifically useful. For this aim, it is essential to first establish the descriptive definition of well-being. Thus, any theory of well-being that makes an explicit or implicit reference to well-being as commonly understood in everyday discourse, requires a descriptive definition of well-being.

 

Despite the prime importance of a descriptive definition of well-being, few social scientists have examined this fundamental question. In addition, most social scientists have ignored the important contributions of philosophers to the science of well-being; with the exception of the obligatory citation of Aristotle writings on this topic more than 2,000 years ago. My contribution to the task of defining well-being is based heavily on the advances in philosophy over the past 2,000 years that provides the basis for the most recent treatments of this topic in philosophy. The main contribution of this article is to demonstrate that modern philosophy makes an important contribution to the descriptive definitions of well-being that provides a useful basis for the evaluation of various stipulative definitions of well-being and associated well-being measures in the social sciences.

 

Well-Being as an Ideal Prototype

 

Like any other construct, a descriptive definition of well-being can define well-being in terms of exemplars (e.g., lives with high or low well-being) or in terms of prototypes that extract common elements of exemplars. For some constructs, prototypes can be defined in terms of the central tendency of exemplars (the prototypical car seats five people, whereas atypical cars may seat less or more people). Other constructs are defined by an ideal prototype. That is the most extreme values are most typical of the construct. For example, an athlete is not defined in terms of average fitness, but rather in terms of the highest level of fitness. For evaluative constructs like well-being, it makes sense to use ideal prototypes to define the construct. For example, most people would attribute a higher level of well-being to somebody with extremely good health than to somebody with average health. The ideal prototype of well-being is a life with that has all imaginable desirable properties (e.g., being rich rather than poor, healthy rather than sick, popular vs. unpopular, comfortable vs. uncomfortable, etc.). The definition of well-being in terms of an ideal prototype has some intuitive appeal. Most people are likely to agree that being rich, healthy, popular, comfortable, etc. is preferable to being poor, unhealthy, unpopular, uncomfortable, etc. The appeal of ideal prototypes is evident in Aristotle's famous writings on this subject when he lists several desirable attributes (friends, honor, wealth, pleasure) as indicative of a life with high well-being (http://www.seop.leeds.ac.uk/entries/aristotle-ethics/).

 

However, the definition of well-being in terms of an ideal prototype encounters several problems. First, despite increasing wealth and scientific advances, it seems utopian to maximize well-being by maximizing every possible desirable aspects of a life. Second, even if it is possible to construct an ideal prototype of well-being, it does not provide a criterion for the evaluation of a life, because it is unclear how discrepancies between the ideal prototype and the actual life should be evaluated. Is a discrepancy in health more important than a discrepancy in popularity? Is a discrepancy in wealth less important than a discrepancy in comfort? Third, an ideal prototype has to be limited to characteristics that are universally evaluated as positive. As a result, life-aspects that are evaluated positively by some and negatively by others are excluded, but these aspects may still contribute to individuals' well-being. For example, being married may be desirable for some, but not for others. In short, it is possible to construct a prototype of a life with high and with low well-being, and the prototypes could be used to define the concept of well-being. However, the definition would not be practical for a science of well-being because it does not provide a qualitative or quantitative criterion for the evaluation of lives.

 

A Taxonomy of Descriptive Definitions of Well-Being

 

A scientifically useful definition of well-being requires a more precise definition that exemplar or prototype definitions. Numerous philosophers have provided descriptive definitions of well-being, including the most well-known attempt by Aristotle. It would be foolish to ignore these prior attempts. Rather, the main task for developing a definition of well-being is to carefully compare the similarity and differences of the various definitions and to evaluate them against each other. The main advantage of classifying definitions into groups is that it is not necessary to examine each individual definition of well-being. If a group of definitions share a common element, it is possible to examine the descriptive adequacy of the shared element. For example, numerous definitions of well-being may include the fulfillment of basic needs as a core aspect of well-being. Closer examination may reveal that the fulfillment of basic needs is indeed an essential aspect of well-being. Accordingly, any definition that includes this component in its definition remains a viable candidate for a descriptive definition of well-being. At the same time, any definition of well-being that fails to take basic needs into account is eliminated from further consideration.

 

Subjective definitions versus objective definitions of well-being

 

Sumner (1996) starts with the distinction between objective and subjective definitions of well-being. The most common type of objective definitions of well-being are lists of objective characteristics that are necessary and sufficient for well-being. However, the defining aspect of objective definitions of well-being is that they do not make any reference to the interests, needs, values, or preferences of the individual who's life is being evaluated. The evaluation of a life is based entirely on the possession of objectively specified aspects that define well-being. In contrast, subjective definitions of well-being require a reference to the individual's own interests, needs, preferences, or desires. Well-being is not the product of objective attributes of an individual's life, but always depends on the subjective evaluation of these aspects from the perspective of the individual living the life.

 

The distinction between objective and subjective theories of well-being has several parallels in the psychology of emotions and values. Biological theories of emotions tend to emphasize innate, hard-wired processes that produce universal evaluations of specific stimuli and action tendencies. In contrast, cognitive theories of emotions tend to focus on the fact that the same stimulus or event can give rise to different emotions based on the relevance of the event to individuals' goals or concerns (Lazarus). Some theories of needs and values focus on universally shared basic or fundamental needs. Other theories focus on the presence of individual differences in values and preferences (Schwartz, Rokeach, Inglehart).

 

It is important to avoid confusions between subjective and objective definitions of well-being and subjective and objective attributes of lives (Sumner, 1995). For example, Aristotle suggested that "a happy life must include pleasure" (http://www.seop.leeds.ac.uk/entries/aristotle-ethics/). Most psychologists and social scientists are likely to think about pleasure as something subjective because pleasure is an experience. However, in the present context the definition of a happy life as a life with pleasure is an example of an objective definition of well-being. The reason is that the definition makes no reference to an individual's own interest, desire, or preference. According to the objective definition of well-being as a life with pleasure, pleasure increases well-being even if an individual would prefer not to experience pleasure. It is also possible that objective attributes of a life are included in a subjective definition of well-being. For example, a subjective definition of well-being could specify the availability of food, water, and shelter as essential aspects of well-being if it makes a reference to the subjective point of well-being. For example, a subjective definition of well-being could state that the fulfillment of basic needs is necessary for well-being. The reference to needs implies that objective factors like food and water are aspects of well-being because every subject evaluates them as desirable. As a result, it is a subjective definition of well-being.

 

Objective Definitions of Well-Being

 

Objective Lists

 

Most objective definitions of well-being are lists. A list enumerates attributes of a life with high well-being. For example, the Oxford dictionary defines well-being as "the state of being comfortable, healthy, or happy" (The Oxford Dictionary of English (revised edition). Ed. Catherine Soanes and Angus Stevenson. Oxford University Press, 2005. Oxford Reference Online. Oxford University Press.  University of Toronto Libraries.  14 April 2008  <http://www.oxfordreference.com/views/ENTRY.html?subview=Main&entry=t140.e87727>)

The main problem of lists is that they fail to specify the reasons for the inclusion or exclusion of attributes on the list. This quickly leads to two common problems of list theories in general. It doesn't take long for different researchers to develop different lists. In psychology there are various lists of "basic" emotions, values, or cognitive abilities. In the beginning, it may be sufficient to focus on the similarities (fear is on most lists of basic emotions) and to ignore differences, but at some point the differences will become more and more salient (is surprise an emotion?). The well-being literature is no exception. Many lists include pleasure (and the absence of displeasure) as important aspects of well-being (Diener, 1984), other theories make no explicit reference to pleasure and displeasure. To resolve these inconsistencies it is necessary to examine the implicit or explicit criteria underlying the selection of items for a definition of well-being.

 

Sumner (1995, 1996) examines two principles that can be used to develop lists definitions of well-being. One approach is based on Moore's private ownership theory of well-being. The main assumption of the theory is that some attributes are intrinsically valuable, good, or desirable. For example, most people prefer beautiful things over unattractive things. As a result, possession of the universally and intrinsically desirable attribute beauty could be on the list, and a necessary - but probably not sufficient - criterion of well-being would be whether a live is beautiful. One problem of this approach is that beauty is not only an attribute of lives. In fact it is quite difficult to attribute beauty to lives, but also an attribute of other objects such as hang bags or landscapes. According to Moore's private ownership theory of well-being, we would have to conclude that a beautiful handbag has higher well-being than an ugly handbag. However, it seems wrong to assign well-being to objects. Thus, defining well-being in terms of ownership of intrinsically desirable attributes is too broad, and lacks descriptive accuracy for a definition of well-being. One solution to the problem is to limit desirable attributes to attributes that only living organisms or even only humans can have. This solution seems unsatisfactory because it limits the range of attributes that produce well-being. Another problem of private ownership theory is that it fails to account for the numerous attributes that contribute to well-being that are not intrinsically desirable or undesirable. For example, for some people an orderly and planned life may be desirable, whereas others may prefer a life filled with spontaneity and surprises. A definition of well-being that ignores this possibility fails to capture the meaning of well-being. Even if these problems could be resolved, private ownership theory would still have to solve the difficult task of identifying the list of intrinsically good attributes that define well-being. The notable absence of such a list highlights the problems of this approach to the definition of well-being.

 

Well-Being as the Balance of Pleasure and Displeasure

 

A more influential example of an objective definition of well-being is Bentham's definition of well-being as the balance of pleasure and displeasure (Bentham, @@@; Kahneman, 1999). It may seem odd to think about this definition of well-being as an objective definition of well-being because feelings are mental states and mental states are considered to be subjective (cf. Scanon, 1993). Once more it is important to distinguish between objective versus subjective definitions of well-being and objective and subjective defining attributes of well-being. Hedonic experiences are subjective in two ways. First, they are often elicited by subjective evaluations of the environment. The same event may elicit pleasure in one individual and displeasure in another. Second, they are subjective because they are only accessible to the individual who experiences them. However, the definition of well-being in terms of pleasant and unpleasant feelings is an objective definition because it makes no reference to an individual's subjective point of view. Even if it were not in the individual's best interest to experience pleasure, the hedonistic definition of well-being implies that experiences of pleasure maximize well-being.

 

The most common objection against hedonistic theories of well-being is that the actual cause of pleasure and displeasure are irrelevant. For example, it does not distinguish between pleasure derived from evaluations of one's own life and pleasure derived from imaginary stimuli (e.g., fantasy, movies). Another problem for the theory is that others objective attributes of a life may be equally or even more important than pleasure. For example, the state motto of New Hampshire is "Life free or die." (http://en.wikipedia.org/wiki/Live_Free_or_Die), and in ancient Rome a poet was disgusted by a people that was more interested in expensive games than in the pursuit of more noble endeavors. This criticism coined the expression "bread and games" for cynical policies that merely try to make citizens feel happy without actually improving their lives. Some contemporary psychologists equally proposed that autonomy is more important than pleasure (Ryan & Deci, 2001). To fend off this criticism, it would be necessary to provide a reason why pleasure or displeasure alone should define well-being. Benthams' original reason sought the answer to this question in human nature: "Nature has placed mankind under the governance of two sovereign masters, pain and pleasure" (http://en.wikipedia.org/wiki/Jeremy_Bentham). However, nature - or evolution - has given human beings more than pleasure and displeasure, and a deeper analysis of evolution reveals that nature only uses pleasure and displeasure as tools to achieve more basic objectives like survival and reproduction. Thus, it seems legitimate to ask why well-being should not be defined in terms of the achievement of these ultimate objectives (a long life with many children).

 

It is important to note that my rejection of an objective definition of well-being in terms of pleasure and displeasure does not imply that pleasure and displeasure are unrelated to well-being. In fact, I will argue that pleasure and displeasure are critically important indicators of well-being, although they are neither necessary nor sufficient for a definition of well-being.

 

Eudamonic Theory

 

The most prominent contemporary objective definition of well-being is named after Aristotele's concept of eudaimonia (Nussbaum, 2000; Ryan & Decci, 2001; Sumner, 1995; Waterman, 1993). The main aspect of eudaimonic definitions of well-being that makes them objective definitions is the focus on functioning. For example, Ryan and Decci (2001) endorse Aristotle's focus on functioning when they write "we wholly concur that well-being consists in what Rogers (1963) referred to as being fully functioning [italics added]" (p. 147).

 

Optimal functioning is an attractive attribute for an objective definition of well-being because the function of an object offers clear evaluation criteria that are independent of any subjective standards. For example, it is possible to evaluate whether a car or a computer is functioning well. In these examples, it is evident that this evaluation does not rely on the perspective of the car or the computer because neither a car nor a computer have a stake in their functioning. My well-being is diminished when my car or computer breaks down, but the well-being of my car or computer is not because objects by definition do not have well-being (Sumner, 1996).

 

Optimal functioning is also a good candidate for an objective definition of physical well-being. The functions of organs are well-defined, and it is possible to assess physical well-being in terms of the ability of all organs to serve their functions. Indeed, Aristotle used body parts as an analogy to support this theory. However, the problem of functioning as an objective definition of well-being is that the analogy between cars, body parts, and lives is flawed. Whereas the function of a car is clearly defined, it is not clear what the objective function of a human life is. Thus, a functional theory of well-being needs to answer a question that may be even more difficult to answer than the question "What is well-being?" Namely, it would have to provide an objective answer to the question "What is the function or purpose of a life?" Without an answer to this question, the definition of well-being in terms of optimal functioning fails to provide a definition because a definition aims to clarify the meaning of well-being. It can only do so, if the meaning of the definiens (i.e., the defining part of the definition) is clear (http://en.wikipedia.org/wiki/Definition). If this is not the case, as in the current case of " the function of life," the definition fails to explain the meaning of well-being.

 

The vague meaning of eudaimonic definitions of well-being becomes apparent in the vastly different theories of well-being that claim to be eudaimonic theories of well-being. For example, the capabilities approach (Sen/Nussbaum) specifies a large number of activities that people are capable of and defines well-being as a life that is filled with options to carry out these activities. Waterman (1993) defines well-being as living in accordance with one's true self, but fails to provide an objective account of the true self. Ryff lists social relations as one of six objective aspect of human functioning, but fails to explain in which way having social relationships is a function of a human life. Ryan and Deci (2001) claim that their definition of well-being as autonomy, competence, and relatedness is a eudaimonic definition, but closer inspection reveals that it is actually a subjective definition of well-being, namely a specific version of a preference-satisfaction theory.

 

My rejection of eudaimonia as an objective definition of well-being, on the basis that it does not provide a definition, does not imply that optimal functioning is not important. In fact, optimal functioning could be related to well-being for one of two reasons. First, it is possible that optimal functioning is a precondition for optimal well-being. For example, Maslow proposed a hierarchy of needs and suggested that basic needs (food, water, air) must be fulfilled in order to pursue and fulfill higher needs. The fulfillment of basic needs is also necessary to maintain optimal functioning. The second reason would be that for many people a subjective evaluation of their lives is likely to be more positive under conditions of optimal functioning. However, even if well-functioning would be highly related to well-being, it would be a mistake to equate the two. Well-being cannot be reduced to well-functioning because lives do not have an obvious, universal, objective function.

 

Subjective Definitions of Well-Being

 

Following Sumner (1995, 1996), I divided definitions of well-being into subjective and objective definitions. The crucial difference between these definitions is whether evaluations are made from the perspective of the individual who's life is being evaluated or whether it is possible to evaluate lives using objective criteria that are independent of the individual's own point of view. In accordance with Sumner's analyses of objective definitions, I found that existing objective definitions of well-being fail to capture the essential meaning of well-being. For a life to go well and for an individual to have high well-being, it seems crucial to take the subjective point of the individual who lives the life that is being evaluated into account. This is by no means a novel or groundbreaking insight. Indeed, it is the prevalent view in philosophy and the guiding principle of democratic, free market economies. Despite the widespread popularity of subjective definitions of well-being, a coherent and widely accepted subjective definition of well-being is lacking.

 

Subjective List Accounts

 

Earlier, I reviewed and rejected objective list definitions of well-being. The main reason was that it is impossible to defend objective definitions in general. Subjective list definitions do not share this problem. The main problem of subjective lists is that human beings are not all the same. The same attribute (e.g., living in a noisy, urban center) may enhance the well-being of one individual and diminish the well-being of another individual. Thus, it seems impossible to create a list with attributes that are subjectively good for everybody. Nevertheless, prominent examples of subjective list theories can be found in the social sciences.

 

Lists of economists tend to focus on the fulfillment of basic needs. Under normal circumstances, most human beings desire to stay alive. To fulfill this desire, they need to fulfill basic needs of food, water, air, etc. Thus, it is possible to define well-being at least partially as having sufficient food, water, air, and adequate shelter for survival. The list is subjective because the value of the items on the list rests on individuals' own subjective evaluation. However, an explicit reference to the subjective point of view is not necessary because the subjective point of view is universal. Identical subjective points of view for life evaluations have many advantages for the creation of measures of well-being. First, it is not necessary to actually measure subjective preferences, which is often deemed difficult if not impossible. Second, it is possible to assess well-being indirectly in terms of the availability of the resources that are needed to fulfill basic needs. For example, it is possible to determine well-being in terms of the amount of water and food that was consumed, although the definition of well-being is subject, in the sense that all people evaluate a life with sufficient water and food as better than a life without sufficient water and food.

The limitations of a well-being account focusing on basic needs are fairly obvious. Simple observations from everyday life as well as survey results show that people want more from life than the fulfillment of basic needs, especially in affluent societies (Inglhart@@@).

 

 

First, by limiting the assessment to basic needs, this assessment is likely to miss many additional aspects of human lives that influence well-being. Second, the focus on basic needs reaffirms the focus on the negative aspects of life. Being able to avoid starvation or injury is necessary but not sufficient for well-being. Third, the focus on basic needs provides little valuable information in modern affluent societies, which ensure that most citizens can fulfill basic needs. This does not mean that these societies have maximized citizens' well-being. Fourth, indicators on the fulfillment of basic needs fail to be sensitive to new problems in modern societies (e.g., the consumption of too many rather than two few calories).

 

An alternative starting point for list theories of well-being could be attempts by philosophers and psychologists to identify universal human needs that go beyond mere basic needs. The most prominent example is Ryan and Deci's (2000) self-determination theory, which proposes that the fulfillment of three basic needs (autonomy, competence, & relatedness) is essential for well-being. However, the authors do not explicitly define well-being in terms of need-fulfillment, nor do they provide a formal definition of well-being. At times, they clearly distinguish between fulfillment of the three needs and well-being, suggesting that these are two distinct, yet causally related constructs. "Our research now focuses on the link between satisfaction of the basic psychological needs and the experience of well-being" (Ryan and Deci, 2000, p. 75). If well-being were defined as fulfillment of autonomy, relatedness, and competence needs, it would make no sense to study the link between fulfillment of these needs and well-being because the two are identical constructs, and something cannot be a cause of itself. Examples of this research program further demonstrate that self-determination theory does not define well-being in terms of fulfillment of the three needs. For example, the authors ask "is within-person variability in basic need satisfaction related to variability in well-being indicators?" (p. 76). This question is only an empirically meaningful question, if well-being indicators are not also measuring need-fulfillment. Thus, these indicators must be based on a different definition of well-being. In fact, the well-being indicators in this study were self-esteem, self-actualization, and the absence of depression and anxiety. Although the authors do not provide a definition of well-being that explains the choice of these indicators, it is evident that well-being is defined in terms of feelings and beliefs about the self rather than in terms of the objective fulfillment of basic human needs. Need-fulfillment only contributes to well-being to the extent that it increases self-esteem and decreases depression. However, to the extent that well-being indicators are also influenced by other factors, well-being is empirically and conceptually distinct from well-being, and the theory offers no definition of well-being nor does it explain how well-being is related to self-esteem or depression.

 

A more general problem of definitions that rely on lists of basic needs is that social scientists do not agree on the number of importance of different needs. The most extensive research program on this issue by Shalom Schwartz (@@@) has identified about 10 basic needs. However, the research program also shows that the relative importance of these needs varies across cultures and individuals. (Schwartz, @@@; Oishi @@@). Thus, while it may be true that everybody values being powerful over being powerless, safe over unsafe, and free over unfree, it is not the case that everybody values being powerful over being save or vice versa. Thus, a list may specify many aspects that are desirable, but it does not provide a basis for the evaluation of lives because an unfulfilled need has different implications for different individuals, depending on the importance that they attach to a need.

 

In sum, even subjective lists fail because they have to assume that there is universal agreement in the evaluation of lives. This assumption contradicts the everyday observation that people with quite different lives both evaluate their lives positively. Whereas one individual likes a life without children, another individual is happy with a life with eight children. Thus, a subjective definition of well-being is impossible without an explicit reference to the individual who is living the life.

 

Well-Being as Preference-Realization

 

Preference-realization is the most popular definition of well-being in contemporary philosophy (Haybron, 2007). Preference-realization defines well-being as the match between a possible live that is most favorable for an individual and the actual life of the individual. If the preferred live is realized in the individual's own life, the individual has high well-being. The definition of well-being in terms of preference-realization implies that well-being has two components. The preference component roots well-being in the subjective point of view of individuals. The realization part emphasizes that well-being is an evaluation of actual lives. Preference-realization is similar, but not identical to related definitions of well-being such as desire-fulfillment. Our concept of preferences is broader than the concept of desires and parallel's Sumner's concept of liking. One important distinction between desires and preferences is that desires are future-directed, whereas preferences are not limited in time. For example, a four-year old boy may desire to become a race-car driver when he is a grown-up. This desire may be relevant for his well-being at age 20, but it cannot be used to evaluate his well-being at age 4 or the well-being in his life so far. In contrast, the same boy may have a preference for vanilla ice-cream over spinach. This preference can be used to evaluate his well-being based on the amount of vanilla ice-creams and spinach the boy has consumed so far. Another important distinction between desires and preferences is that desires are by definition unfulfilled and often cease to exist, at least temporarily, after they have been satisfied. As a result, they fail to provide a stable point of view to evaluate lives. For example, feelings of dissatisfaction accompany attempts to reach a hard goal like completing a book in time, but at the time the book is completed, the desire to do so vanishes. As a result, there is never a match between the actual state of affairs and the desire. In contrast, preferences do not have this property. For example, just because Jill actually has a nice house, she does not loose her preference for having a nice house.

 

We also avoid the definition of desire-fulfillment because desire has a strong affective and sometimes immoral connotation. The definition of well-being as preference-realization is not limited to burning desires of the flesh or the soul. It merely assumes that individual's are not passively living lives without any interest in what happens in their lives. They have a stake in their lives. They care about their lives. And they have preferences regarding the things that have happened and are currently happening in their lives.

 

We prefer the term realization over satisfaction or fulfillment for two reasons. First, both satisfaction and fulfillment have an affective connotation that imply a pleasurable experience. As such it makes more sense to say that a desire or a need was satisfied or fulfilled than to say a preference was satisfied. However, preferences can be realized, that is my life may or may not have the aspects that I prefer. The term realization also implies that well-being is an evaluation of actual lives rather than my beliefs about my life. If I prefer to be married to a loving spouse, my well-being depends on actually having a loving spouse or not. It is not sufficient to merely belief that I have a loving spouse. As a result, the definition implies that positive illusions about one's live create well-being. At the same time, people may have preferences for illusions. I may prefer to imagine climbing Mount Everest as opposed to actually doing so. In this case, the illusion rather than the actual state of affairs would realize my preference.

 

In sum, the definition of well-being as preference-realization implies that well-being has to be evaluated on the basis of individual's subjective preferences about their lives. The main appeal of defining well-being as preference-realization is that the definition is subjective and allows for individual differences in the subjective point of evaluation. Not everything that is good for one individual is good for another individual. As a result, the definition overcomes the main problem of objective definitions of well-being. However, the definition encounters a number of new conceptual and empirical challenges. We first show how our definition meets these challenges. We then address the problems of measuring preference-realizations.

 

Preference-Realization Can Be Immoral

 

A minor problem of the definition is that the old terminology of desire-fulfillment evoked images of rampant consumption, endless need gratification, and greed. Many moral philosophies and religions (e.g., Buddhism) teach detachment from desires as a way to a good life. As noted earlier, this is a misunderstanding that I try to avoid by defining well-being in terms of preference-realization rather than desire-fulfillment. An individual who wants to meditate and is able to do so is realizing a preference (meditating over doing something else) just like somebody who wants to drink a bottle of expensive wine and is able to do so is realizing a preference.

 

A more serious challenge of defining well-being as preference realization is that individual's can maximize well-being by realizing immoral preferences. For example, if I have a preference to own a Porsche, and I do not have a preference to not harm others, I could increase my well-being by stealing a Porsche. One solution to this problem is to exclude "anti-social" preferences from the set of preferences that can maximize well-being (Harsanyi, 1977). As appealing as this modification may seem, it is both conceptually problematic and impractical. Well-being is not a moral construct (Sumner, 1996). The problem of criminal acts is not that the perpetrator does not gain from it; the problem is that the victim looses well-being. If we define the gain in well-being by the perpetrator away, by excluding immoral gains, we first of all loose the power to explain why criminals would engage in criminal behavior. What is a perfectly rational, if morally reprehensible, behavior if we assume that immoral behavior can increase well-being becomes an irrational act that cannot be explained. Second, the exclusion of immoral gains does not imply the exclusion of immoral losses. That is, after an immoral act that is excluded from the well-being of the perpetrator, the victim does suffer a lose in well-being. But in which way has the well-being of the perpetrator decreased: namely, by making his or her life less consistent with his or her preferences. If we allow for well-being to decrease as a function of a stolen car, it should also increase as a function of steeling a car. Maintaining equal definitions of well-being for perpetrator and victim reveals that the immoral act produced a transfer in well-being from the victim to the perpetrator. Thus, an amoral theory of well-being is actually needed to make moral judgments because question of morality take into account how much harm an immoral act caused (Sumner, 1995). No harm, no foul! Finally, it is misleading to suggest that preferences per se can be immoral. Most criminals have the same preferences as their victims. For example, they both want to drive a Porsche. What is immoral is the attempt to maximize well-being by realizing one's preference by means of an immoral act. The definition of well-being as preference-realization also does not encourage immoral behaviors. One way to align well-being with moral behavior is to instill moral preferences in individuals. An individual who has a preference to act in a moral and responsible manner, can achieve well-being only by acting morally and responsible. Moral issues are also largely irrelevant for the creation of national accounts of well-being. Because immoral acts not only increase the well-being of perpetrators, but also decrease the well-being of victims, an increase in immoral acts cannot increase well-being.

 

Irrelevant Preferences

 

Another objection to preference-realization as a definition of well-being is that people have preferences about an infinite number of things. For example, psychological studies show that a few exposures to any neutral stimulus can create a preference for it (Zajonc @@@). It seems implausible that realizations of all preferences are relevant for individuals' well-being. This is not a major problem for the definition of well-being as preference realization. A simple solution to this problem is to assign preferences an importance weight. The weight for many preferences will be at a vary low level that for practical purposes can be set at zero. As a result, the definition allows for the fact that people do have a vast number of preferences, while limiting the preferences that are relevant for an individual's well-being to a more manageable number. Consistent with this definition, empirical studies of well-being judgments show that people weigh life-aspects in accordance with the subjective importance attached to these attributes (Andrews & Withey, 1976; Schimmack & Oishi, 2005). For example, most people have preferences about the weather (e.g., they prefer dry, warm, sunny days over hot and muggy or cold and rainy days). However, many respondents rate weather as a relatively unimportant attribute, and satisfaction with weather is often unrelated to satisfaction with life in general.

 

Adaptation and Preference Realization

 

Another common objection to defining well-being as preference-realization is the concern that people's lives may get better or worse in an absolute sense, but fail to produce changes in well-being due to parallel changes in preferences (Haybron, 2007). The most commonly discussed shits in preferences is adaptation.

 

The theory of adaptation is based on an analogy to human's sensory perception. For example, if somebody on a bright, sunny day goes into a house, he or she first has a hard time seeing. After a few minutes, the eyes adapt to the dark room and the person can see well (well-functioning). Similarly, if somebody steps out of a dark room into the bright sunlight, visual perception is first impaired. After some time, the sensory system adjusts to the new conditions, and it functions as well outside on a bright sunny day as it does inside a dark room. Adaptation theories assume that similar processes influence individuals' evaluations of their lives. If life objectively gets better, preferences increase, neutralizing any well-being gains. If life objectively gets worse, preferences decrease, again neutralizing well-being gains. As a result, an individual with an objectively good life has the same level of well-being as an individual with an objectively bad life. Moreover, they would both have high well-being because their actual life matches their preferences.

 

Common sense indicates that there are limits to adaptation. Just like the visual system fails to adapt to extreme conditions (e.g., a pitch black room), there are limits to adaptation of preferences (Diener @@@, 2006). There are many factors, ranging from innate preferences to cultural norms that restrict the range of preferences. As a result, there are many life circumstances outside the preference range that prevent adaptation. Once more, the realization of preferences that are essential for survival are a salient example. However, adaptation may occur within the range of possible preferences. For example, an individual may have a preference to have children, but is actually unable to have children, a student may desire to become a doctor, but is unable to get into law school, or somebody may prefer a specific consumer product that is no longer produced. Eventually, these individuals loose their preferences, which increases their well-being. These examples would be problematic for the definition of well-being as preference-realization, if it could be argued that a life with children is objectively better than a life without children, if a life as a doctor is better than a life not being a doctor. In other words, if need to be able to evaluate lives from an objective perspective that is independent of an individuals' preferences to challenge preference-realization as a definition of well-being. As we demonstrated earlier, it is impossible to determine well-being objectively. Thus, adaptation is a property of well-being, but this property does not undermine the construct.

 

Adaptation process may pose bigger challenge later on, when we discuss observable indicators of well-being. For example, people's self-reports of well-being or preferences may provide false information. To give an example, Jill has a preference to be romantically involved with Jo, but Jo is in a different romantic relationship. Jill's unrealized preference lowers her well-being. After a while, Jill declares that he or she is no longer interested in Jo. As a result, we would infer that her well-being increased. After some time, Jo's relationship ends, and Jo shows an interest in Jill. In one scenario, Jill informs Jo that she is no longer interested in a relationship with him. This scenario is perfectly consistent with our definition of well-being as preference-realization. However, in the other scenario, Jill happy accepts Jo's overture, and Jill and Jo become a very happy couple. The latter scenario makes us doubt whether Jill's well-being was really as high as we inferred based on her declaration that she is over Jo. However, this is not a problem of our definition of well-being as preference-realization. The problem arises because we assume that Jill continued to have a preference to be with Jo, despite her declaration to the contrary. Similarly, we may doubt whether individuals truly adapt to circumstances like poverty, unemployment, or disability. However, these doubts do not challenge the definition of well-being as preference realization. They raise concerns about the possibility to accurately assess people's preferences.

 

Preferences vs. Aspirations and the Aspiration Spiral

 

Some researchers have been concerned by the fact that objective indicators of well-being like income or a nations' GDP suggest that well-being increased considerably, but that subjective measures show relatively little or no increases in well-being (Hagerty and Veenhoven 2003) Easterlin, 1974). Another worrying finding is that people's income aspirations are highly correlated with their actual income. One interpretation of this finding is that aspirations constantly increase objective life-circumstances, but that well-being fails to increase due to rising aspirations. Thus, objective life-circumstances and aspirations rise in tandem, but well-being fails to increase because it is defined as the match between life-circumstances and aspirations, and life-circumstances always lag aspirations. It is a problem for a definition of well-being that fails to reveal constant improvement in people's lives. The first problem of this criticism is the implicit assumption of an objective standard to determine that lives have improved. It is possible that improvements in some aspects have produced negative side-effects in other aspects of people's lives. However, a more serious problem of this criticism is that it confuses aspirations and preferences. We define well-being as preference-realization, which is distinct from aspiration-satisfaction.

Preferences are evaluation criteria that are used for the evaluation of one's current life circumstances or life circumstances over a defined period in one's past life. In contrast, aspirations are future directed. Unlike preferences that can be realized or not, aspirations are by definition unfulfilled because the future is by definition unrealized, and aspirations cease at the moment they are realized or people realize that their realization is impossible. Thus, aspirations and preferences fulfill essentially different functions. Aspirations guide future actions. Preferences are used to evaluate the consequences of past actions. Because aspirations are aimed at the future, thy can only promise well-being, but whether realization of aspirations actually produces well-being depends on whether a realized aspiration also realizes a preference. For example, Jill has the aspiration to make $1,000,000. When Jill makes $1,000,000, the aspiration to make $1,000,000 is realized and disappears. She may now have a new aspiration to make $2,000,000. Does this mean her well-being did not increase or even decreased? No, her well-being is not based on her aspiration for the future, but her preferences for the present. Is she satisfied with having currently $1,000,000 or not? Currently having $1,000,000 and being satisfied with this amount in the present also does not mean that she does not want to have more in the future. Thus, constantly increasing aspirations can co-exist with high well-being.

 

Creation of New Preferences

 

Individuals' preferences are limited by the range of preferences that are available. Before the invention of planes it would have been unrealistic and foolish for somebody in North America to have a preference to go for a two-week trip to India to attend a wedding. Nowadays, thousands of people make these trips every month, and it is a reasonable preference. Ironically, the availability of this new preference would produce a decrease in well-being because some people may be unable to realize this preference. In contrast, nobody had that preference 40 years ago. As a result, nobody had an unrealized preference to go for a two-week trip to India. The main problem of this argument is that preferences can exist independent of the technological possibilities at a certain time. The preference is not to sit for 24 hours in a narrow seat in a noisy plane. The preference is to get to India as comfortable and as quickly as possible. If a flying carpet could do it in 8 hours with the same degree of comfort and safety, most people would prefer a flying carpet over a plane. Planes were only invented and commercialized to realize an existing desire to reach far destinations as quickly as possible. Thus, the technological invention of airplanes only superficially create new preferences; viewed differently the invention helped to realize an already existing preference of traveling faster to far destinations. We are not proposing that every new invention has positive effects on well-being. For example, air planes also increased mobility and created a world in which close family members live thousands of miles apart. Thus, it has become more difficult to realize a preference to spend time with family members.

 

The vast differences in life circumstances and preferences of nomads in Northern Africa and high-tech professionals in California, or between US Americans in 1808 to the well-being of US Americans in 2008 may still preclude a meaningful comparison of their well-being. However, the main purpose of a national account of well-being is to assess differences in well-being within a nation, say the United States, and changes in well-being over shorter time periods. Although lives are changing fast, and new technology creates new preferences (say watching Utube, or connecting with friends on Facebook), we believe that these changes are superficial and it is possible to examine whether these new technologies produce a net gain in well-being.

 

Preferences can be manipulated

 

A related criticism to the adaptation challenge is the concern that it is too easy to manipulate people's preferences (Sen, 1987 cited in Sumner, 1996). For example, the traditional Indian cast system may prevent people from forming preferences about jobs or their status in society. The cast system can be used by privileged casts to enjoy a better life, while the lower casts are subjectively as happy because their preferences match the norms of social casts.

            We realize that this is a concern for our definition of well-being as preference-realization. However, there are several reasons why this concern is not a fatal blow to this definition of well-being. First, the concern assumes an objective criterion to evaluate lives. We have to assume that the life of higher casts is better than the life of lower casts by some objective standard. Second, we have to assume that preferences can be easily manipulated, whereas history suggests otherwise, whether we use the French Revolution or the Fall of the Berlin Wall as an example.

            There are also several remedies that can be used to address distortions of this kind in subjective accounts of well-being. First, we are not proposing that well-being is the only criterion for social policy. For example, men and women report equal levels of well-being. This fact does not imply that society should abolish the goal of equal employment opportunities for men and women in the workplace. Second, Sumner (1996) proposes that preferences can be examined in terms of their origin. Only preferences that are formed under free conditions should be used to assess well-being.

It would be a mistake to dismiss subjective indicators of well-being because objective indicators fail to provide an alternative. The best approach is to consider the information from objective and subjective indicators of well-being in policy decisions. Without subjective information, a main concern is that the objective indicators fail to reflect individual's own evaluations of their lives. Without evidence that preferences are ill-conceived, subjective indicators are likely to provide a more accurate picture of well-being. An analogy is voting in democratic societies. Unless it can be shown that votes were bought or votes were manipulated in other ways, we accept individual's votes as valid reflects of their political preferences. Similarly, "a person's own view of her life satisfaction carries an initial presumption of authenticity, and thus of authority. It can be mistaken, even deeply distorted. But it must be shown to be so before we can have any grounds for discounting it" (Sumner, 1996, p. 171).

 

Preference-realizations are too unstable because people's preferences constantly change.

 

One criticism of defining well-being in terms of preference-realization is that people's preferences can change. If preferences would change frequently and dramatically over short periods of time, well-being would fluctuate dramatically. Most of these changes would have little to do with changes in people's actual lives. According to this scenario, it would be futile to implement policies that change actual life circumstances because it is too uncertain what the preferences in the future will be. Evidently, individuals' preferences change over time. The preferences of a 4-year old are different from the preferences of a 40-year old. These individual changes over the life-span do not undermine the value of national accounts, as long as the preferences of 4-year olds remain constant from generation to generation. Empirical research also does not show wildly changing preferences. For example, preferences for music, food, or political parties are highly stable.

 

Towards the Measurement of Preference-Realization

 

We have defined well-being as preference-realization. To use this definition for the creation of national accounts of well-being, we need to find empirical indicators or measures of preference realization. We may do so either directly or indirectly. A direct approach would require an assessment of individuals' preferences, at least all of those preferences that make a significant contribution to the individuals' well-being. That is, trivial preferences (e.g., the color of bank notes) may be excluded.

 

The most straightforward approach to the measurement of preferences may seem to be to ask people about their preferences. However, this approach makes a number of assumptions that may be violated. The standard assumptions of any self-report measure are that individuals are willing and able to make accurate reports, in this case, reports of their preferences. Both assumptions may be violated for a number of reasons. Prominent theories in psychology assume that preferences may not be consciously accessible. Moreover, it is not sufficient to assess merely the presence or absence of preferences, it is also important to assess the relative importance of preferences. People may be able to report accurately that they prefer freedom over being unfree and safety over danger, but they may not be able to report accurately whether their preference for freedom is stronger than their preference for safety. A practical problem of assessing preferences is that people have a large number of preferences. Even if only a small set of these preferences are relevant for their well-being, it is difficult to assess all of them. Moreover, even if assessments of preferences were limited to a small set of the most important preferences for each individual, the set of preferences would vary from individual to individual. This variation in the nature of the preferences creates problems for the creation of national accounts of well-being.

 

Thus, subjective well-being indicators typically do not assess people's preferences. Rather, they aim to assess more globally the total realization of preferences. The major existing indicators of well-being use different approaches to obtain empirically observable indicators of well-being. Each approach is based on a set of simplifying assumptions. As a result, none of these indicators is likely to provide a perfectly accurate measure of well-being. However, the combined information of all indicators is likely to provide valid and very useful information about well-being.

 

Monetary Indicators of Preference-Realization

 

We start with the oldest and most influential approach to the measurement of well-being in economics. In economics, well-being is typically called utility. Although the term utility is also used more narrowly in applications of economic theory that are not concerned with well-being, economic theories of well-being equate well-being with utility (Sumner, 1996). One of the most widely discussed indicators of well-being is gross-domestic product (GDP), and changes in GDP are assumed to produce changes in well-being.

 

For non-economists it may be surprising to learn that the measurement of well-being in terms of wealth is based on a subjective definition of well-being in terms of preference-realization. The reason is that wealth is only a convenient objective indicator for the subjective construct of preference-realization. The subjective nature becomes apparent when we observe the vast differences between individuals in the way they spend their money. It is also important to emphasize that the focus on money is not a reflection of materialism or a desire to accumulate wealth. Indeed, the main assumption of economic theories of well-being is that people spend their money in exchange for market goods (objects, services, membership fees for organizations, health care) to realize their preferences. A billionaire who stuffs his billion dollar under his mattress (or into a stock portfolio) and lives like a homeless person, would have the well-being of a homeless person, unless his only preference were to be a billionaire.

 

Economists' reliance on wealth or income as an indicator of well-being is based on a theory that links money with well-being. The main assumption of the theory is that people are rational and that their choices maximize well-being. If an individual chooses option A over option B, economists infer that option A produced greater well-being than option B. This fundamental assumption implies that all individuals have the maximum level of well-being that is afforded by the options that is available to them. Importantly, this assumption does not imply that that all individuals have the same level of well-being. For example, an average New Yorker has the choice to drink water from the Hudson River, from a tab, or buy bottled water. Most New Yorkers choose not to drink water from a polluted river. In contrast, a poor child in a developing country does not have the same choices, and may be drinking polluted water because it is the only option available. Thus, the well-being of the New Yorker is higher than the well-being of the poor child because it is save to assume that given the same choices as the New Yorker, the child would also drink purified water from a tab or bottle. Thus, a person's well-being depends on the range of options that is available to her. For marketable goods in a perfect market place, the range of options increases in proportion to an individual's wealth (disposable income). The wealthier an individual, the more attainable are the better options. Thus, wealth provides an indicator of well-being. However, an important theoretical question is how strong the link between the indicator and well-being actually is. It is not news for economists that the link is weakened by violations of several assumptions of the theory.

 

Figure 1 shows the assumptions in terms of a causal model that links money to well-being.

 

                  Choice              Market           Costs                .

WB = PR     <=         RO       <=     $$$     <=   Work

 

WB = Well-Being

PR = Preference Realization

CH = Choice

OR = Options Range

$$$ = Wealth

Inc = Income

Wk = Work

SR-Inc. = Self-Reported Income

 

Choice. The first link in the model is between option range and preference-realization. To realize preferences it is not sufficient to have a range of options, but to actually choose on of them. Consumers face several problems when they have to choose amongst various options. Even with regard to a single consumer product, say a new TV set, choosing the most option is difficult. The choices become even more difficult when consumers have to decide how to allocate resources across several preferences. Is it more optimal to buy a smaller house and a bigger car or a bigger house and a smaller car? It would be foolish to assume that every purchase is an optimal allocation of money. It is equally implausible that people are entirely irrational in their purchases. However, it is difficult to determine how good people are in the use of money to maximize well-being. The uncertainty about this link creates uncertainty about the usefulness of money as an indicator of well-being. Furthermore, without a complementary indicator of well-bieng it is impossible to test the validity of this assumption. This uncertainty creates ample room for dissent. Not surprisingly, proponents of the economic model assume that most people most of the time use their money rationally. Critiques often focus on examples of foolish allocations of money.

 

Market. The second link in the model links wealth to the range of options. There are several factors that weaken this link in the theory. The most important one being that not all preferences can be realized in the economic market place. This problem is well recognized in economics, but solutions to this problem are unsatisfactory (Dolan). Other problems are inefficient markets, and the fact that some people may require different amounts of money to realize the same preference. For example, a handicapped individual may require more money for mobility than other people. An individual with a vegetable garden can have fresh organic produces for much less money than an individual who lives in Manhattan.

 

Input/Output. Another neglected aspect in the standard economic model of well-being is the influence of work on income. The only aspect of work that matters is the amount of wealth that is generated.

 

Measurement of Wealth

A lesser, but still important problem of using wealth as a measure of well-being is that even the assessment of wealth is not trivial. At the national level, wealth is being assessed with high reliability and validity by means of an extensive and costly assessment (@@@ reference GDP computation). At the individual level, most studies use self-reports of household income to assess wealth. @@@ validity study of this measure ? @@@ Factors like other sources of income, debt, and savings can distort the relation between income and wealth.

 

Summary

In sum, a number of assumptions are necessary to link income to well-being. The strengths of these links in the causal theory is not known, but it is likely that the actual relation between income and well-being is far from perfect. More importantly, it remains unknown. Thus, at a minimum, alternative measures of well-being can be used to start testing some of these assumptions. Subjective indicators provide an alternative approach to the assessment of well-being. We are not claiming that these measures are perfect, nor do we currently know with certainty that these measures are superior to economic measures. However, these measures are likely to add valid additional information about well-being that can correct biases in existing economic indicators.

 

Affective Indicators of Preference-Realization

There are two processes that link affect (i.e., people's good and bad feelings) to well-being. First, feelings respond to the realization of preferences. Second, feeling good (and not bad) is an important preference of most people. Unfortunately, feelings are not directly observable. The most common approach is to use people's self-reports of their feelings as the observable measure of well-being.

 

To clarify, not all emotion theories assume that subjective experience of pleasant or unpleasant feelings exist or are necessary components of emotional states. However, the aim of a well-being theory is not to assess all aspects of emotions, it only assumes that people experiences pleasant or unpleasant feelings and that these feelings respond to the fulfillment of desires. If this were not the case, affect measures would be useless for the assessment of well-being. Consistent with this assumption, most theories of the causation of emotional states assume that emotions are elicited in response to a subjective appraisal of the environment. There is also strong evidence that the valence of the evaluation is the most important aspect for qualitative distinctions between emotions. Emotions of the same valence tend to be seen as more similar and to be elicited more frequently concurrently than emotions of opposite valence. Not surprisingly, the assessment of well-being in terms of pleasant and unpleasant feelings is very appealing and has deep historical roots (Bentham, Bradburn, Diener, Kahneman).

 

Desire-Fulfillment = Well-Being -> Pleasant/Unpleasant Feelings -> Report of Feelings

 

A simple comparison of the number of links between the ultimate unobservable construct and the indicator of well-being suggests that self-reports of feelings are much closer to the construct of well-being than self-reports of income or even objective income for that matter. However, this does not imply that self-reports of feelings are better indicators of well-being. Which indicator is a better indicator of well-being depends on the strength of the causal links between well-being and the indicator.

 

The emphasis on income rather than feelings can be traced to the rise of behaviorism in the 1930s in economics and psychology. In psychology, several researchers were developing and testing affective theories of well-being in the first decades of the 20th century (Beebe-Center, 1932). Behaviorism killed this program of research and the scientific study of feelings in psychology remerged only gradually in the 1960s (Bradburn, 1969; Schacter & Singer, 1962; Nowlis, 1965), in which psychology started to be dominated by 'cognitivism.', which equally ignored people's feelings. It was only after the 'affective revolution' in the 1980s that psychologists rediscovered feelings (Bower, 1981; Frijda, 1986; Schwarz & Clore, 1983). Since then the scientific study of feelings has increased dramatically. For example, the most widely used self-report measure of affective states has been cited over 3,000 times (Watson, Clark, & Tellegen, 1988).

 

Similarly, affective theories of well-being in economics were discredited in an influential article by Robbins (1938). Robbins (1938) main claim was that it is impossible to say anything scientific about differences between individuals' feelings. That is, it is impossible to say whether Tom is happier than Peter. The strong impact of Robbins (1938) arguments can only be explained by the prevailing zeitgeit. Indeed, Robbins (1938) himself was astonished by the strong - both positive and negative - response to his relatively short contribution. "This is a long story about the genesis of two or three pages in an essay that was written some time ago, and which was never expected to be the subject of much discussion." (p. 640). It is remarkable that the rejection of hedonic experiences in economic theories appears to be based on two or three pages of casual observations. One reason for the lack of scrutiny of Robbins main claim was that the concept of utility is not essential to many important economic problems (e.g., theories of inflation, etc.). Even economists concerned with well-being in the branch of welfare economics found ways to address their main problems without an explicit theory of well-being. Thus, economists felt little need to revisit Robbins claim and for a long time a look into psychological textbooks would have provided no compelling reason to revise economic theories of well-being. However, today - 30 years after the affective revolution in psychology - a large body of evidence suggests that interpersonal comparisons of feelings are possible. It is time to replace Robbins's (1938) armchair philosophy about the happiness potential of a Brahman and an Untouchable in India with some real scientific evidence about humans' emotional experiences. Fortunately, there are signs of an affective revolution in economics (Kahneman, 1999).

 

Most of the debate about the use of feelings as indicators of well-being in the social sciences has focused on the link between internal experiences and self-reports of these experiences. However, for the use of feelings as indicators of well-being, it is equally important to examine the link between well-being and feelings. There are two reasons why this link may be weaker than affective desire-fulfillment theories postulates. First, some feelings may be elicited by other causal factors than the fulfillment of desires. The most obvious example is that people can - and do - alter their hedonic feelings by taking drugs that directly influence the neurological processes that produce experiences of pleasant feelings in the brain. Behavioral and self-report evidence clearly demonstrates that these drugs produce pleasant experiences. It is also evident that these changes are not produced by an altered perception of one's life. Psychologists therefore distinguish two types of affective experiences. Emotions are intentional states that are directed at an object (I am happy about my life). In contrast, moods are not directed at specific objects (I simply feel happy). Using this distinction, emotions reveal fulfillment of desires, but moods do not. To the extent that some hedonic experiences are moods rather than emotions, indicators that rely on all pleasant and unpleasant experiences are imperfect indicators of well-being. However, this is not necessarily the case. One reason why moods could also reflect well-being could be that people have a desire to feel good. As a result, pleasant feelings are not indicators of well-being because they reflect the fulfillment of other desires, but because the experience of pleasant feelings is a desire, and experiences of pleasant feelings fulfill this particular desire. In this case, pleasant feelings would be a sufficient indicator of well-being only and only if people desired pleasant feelings, and if this was their only desire. The main criticism of traditional or preference hedonism is that this assumption is too strong. Studies of people's value preferences do not show that feelings of pleasure are the ultimate motive (Schwartz, Oishi).

 

The second problem for affective desire-fulfillment theories is that some desire-fulfillments may not elicit an affective response. Some evaluations may be purely cognitive. A large body of research in psychology has shown that evaluations vary along a hot-cold, cognitive-affective dimension. Evaluations of some attitude objects (e.g., foods) are primarily affective, whereas others (e.g., political candidates, policies) are primarily cognitive (Esses @@@). Affective desire-fulfillment theories implicitly assume that desire-fulfillments should be weighted by the affectiveness of an evaluation. However, this assumption seems problematic because the affective system is historically older and evolved primarily to solve problems that most human's encountered in their ancestoral environment. Thus, the affect system may be biased toward problems that were historically essential, but may fail to respond adequately to newer concerns and problems that require more complex cognitive evaluations. Take cheesecake as an example. From an evolutionary point of view, cheesecake with its high sugar and fat content is exceptionally good to fulfill the basic need of nourishment. In an environment with scarce resources it would be foolish not to eat as much cheesecake as possible - and may be to share a bit with close others. Not surprisingly, the affect system evolved with an innate preference for sweet taste. However, in today's affluent societies, many people have other concerns that are in conflict with eating copious amounts of cheesecake. However, these desires are not built into an ancient affect system that evolved over hundreds of generations. Thus, it is possible that individuals who follow the desire to eat large amounts of cheesecake experience more pleasure than individuals who follow the desire not to eat cheesecake, even if the strength of the dominant desire is identical. The asymmetry would result merely from the fact that some desire-fulfillments have a stronger impact on the affective system that produces feelings of pleasure. This would be for a desire-fulfillment theory of well-being because the theory introduces an objective aspect in the evaluation process. Well-being defined as the experiential output of the affective system is no longer based on an individual's subjective point of view what is good for her or him. It is now based on the objective characteristics of the processing of information in the human affect system. It ignores the possibility that other systems of information processing that evolved later may lead to a different evaluation of what is good for him or her.

 

It seems likely that the prominence of an ancient evolved part of the brain in hedonic theories plays a role in the rejection of hedonistic theories of well-being. One problem is that the affective system is more likely to create ethical problems. However, as we argued before, we do not think that this is a problem for a hedonistic theory of well-being. The reason is that an individual who ruthlessly pursues maximizing of pleasure could indeed have a life that is better for this individual. The real problem is that human beings are probably the only beings who can transcend the evaluation of their lives on the basis of their feelings. This does not mean that their feelings are unimportant or should be ignored. Rather it means that humans can pursue desires that are independent - or at least more loosely connected - to the affect system. Thus, hedonism seems to neglect the uniqueness of humans, which requires a unique assessment of human well-being that goes beyond indicators that would also be appropriate for the assessment of animal well-being.

 

For contemporary psychologists our distinction between affect and cognition, ancient and modern brain systems may appear too simplistic or even misleading. In the brain, everything is connected with everything and often cognitive processes (thinking) and affective processes (feeling) are interconnected. There are primitive cognitive processes (recognition) and complex feelings (guilt, compassion). We acknowledge that this is the case. However, we also believe that there remain some fundamental differences between cognition and affect that can create biases in evaluations that influence our well-being. How strong did you respond emotionally the last time somebody cut you off in traffic or insulted you? How strong did you respond emotionally to the last news about global warming? Which of these two events has a greater impact on your well-being?

 

Judgment Theories of Desire Fulfillment

 

Desire-Fulfillment = Well-Being -> Self-Report of Desire Fulfillment

 

We end with judgment theories of desire-fulfillment. Historically, this theory is the newest class of theories, and started to emerge only when social scientists first created social indicators of well-being in the 1960s (Cantril, Andrews & Withey, 1976). The appeal of judgment theories of well-being is that the link between the unobservable construct well-being and the observable indicator of well-being is the shortest link. To assess desire-fulfillment, individuals are simply asked to report how well their desires are fulfilled. These reports can take various forms. In contemporary survey research, desire-fulfillment is often assessed with a single question (e.g., Taken all things together, how satisfied are you with your life today?). The assessment of desire-fulfillment with a single item has raised concerns about people's ability to provide a valid answer to a complex question about one's entire life (Schimmack & Oishi, 2005; Schwarz & Strack, 1999). However, judgment theories of well-being do not have to assume that a single item is sufficient to answer this question. It would merely be convenient if people could provide a valid answer to a single question. Alternative approaches could ask participants to list their most important desires and to rate how fulfilled/satisfied they are with each one. These responses could then be combined using subjective weights of the desired.

 

The theoretical advantage of judgment theories of desire-fulfillment over hedonic theories of desire fulfillment is that judgment theories dispense with the assumption that all fulfillments of desires elicit an affective response. That is, they are open to the possibility that some human desires transcend more primitive affective desires. At the same time, judgment theories do not preclude the influence of affective processes. Many human judgments directly incorporate feelings in evaluations if people choose to do so because they consider their affective response relevant (Schwarz & Clore, 1983). For example, people may say (I like pizza simply because eating pizza elicits very pleasant feelings in them). Thus, cognitive theories are not the mere opposite of affective theories. They are more inclusive because they allow individuals to use cognitive and affective processes to determine what is good for them.

 

So, what is the problem with judgment theories of desire-fulfillment? Given the short link between the unobserved construct and the indicator, the problems focus on people's ability to provide adequate reports of their desires, fulfillment of these desires, and the ability to provide proper weights for the importance of different desires to their overall well-being (Kahneman, 1999; Schwarz & Strack, 1999). Biases may occur at various states during the complex task of integrating information about desire-fulfillment in various aspects of one's life. Examining the presence of biases in well-being judgments is a complex and difficult empirical task. A large portion of this book is devoted to the examination of the large body of evidence on this issue. Here it is sufficient to say that it is possible to examine biases in judgments of well-being empirically by means of a process called construct validation. Our judgment theory of desire-fulfillment implies that there are numerous ways to assess the validity of well-being measures. For example, if well-being is the fulfillment of desires, the theory predicts that well-being judgments should be insensitive to the momentary weather on the day a well-being judgment is made. If a study finds that well-being judgments of participants who were randomly selected to be interviewed on a sunny or rainy day differ, the finding shows a bias in judgments of well-being. If on the other hand, reports of well-being by the same individuals on two consecutive days are highly correlated with each other, the results are consistent with the theory that well-being judgments are based on desire-fulfillment and not on minor events that vary from day to day (Schimmack & Oishi, 2005). We can also examine similarities and differences between different indicators of well-being. If two indicators of desire-fulfillment (e.g., average wealth and well-being judgments of nations) are highly correlated with each other, it suggests that both indicators are valid indicators of well-being. When two indicators produce discrepant results, it is important to empirically examine the causes of this discrepancy. In short, we have proposed a general theory of well-being that has several observable indicators that are linked more or less directly to a common shared construct of well-being. Empirical studies can be used to elucidate the strength of the various links, which ultimately leads to the creation of increasingly better indicators of the central unobservable construct of well-being. The only alternative to this approach is to abandon the construct of well-being and to acknowledge that public policies may have numerous laudable objectives (wealth, well-functioning, longevity) that are desirable for a good reasons (e.g., they promote well-functioning, they conform to ethical norms, a majority of voters voted for it), but it would be impossible to say that these policies actually made lives better for the people from the subjective perspective of the people who live these lives. Any reference to people's well-being would be circular (e.g. why did the majority vote for this policy? Because it increases well-being. Why did the policy increase well-being? Because the majority voted for it.) or a category mistake (e.g., confusing well-functioning with well-being).

 

Our desire-fulfillment theory of well-being and the use of monetary, affective, and indicators of well-being is not a challenge to standard economics theories of welfare. As we discussed, we believe that at the level of the unobserved latent construct well-being and ultility are identical. We also do not propose that the sophisticated indirect approaches developed by economists should be abandoned. Rather, we are proposing that alternative indicators based on self-reports were prematurely abandoned in the 1930s. We show that these measures can provide new insights into well-being and have the potential to contribute to policy decisions.
