Just Trying to Help
Sanjiv Erat & Uri Gneezy
Management Science, forthcoming
Abstract:
In this paper we distinguish between two types of white lies: those that help others at the expense of the person telling the lie, which we term altruistic white lies, and those that help both others and the liar, which we term Pareto white lies. We find that a large fraction of participants are reluctant to tell even a Pareto white lie, demonstrating a pure lie aversion independent of any social preferences for outcomes. In contrast, a nonnegligible fraction of participants are willing to tell an altruistic white lie that hurts them a bit but significantly helps others. Comparing white lies to those where lying increases the liar's payoff at the expense of another reveals important insights into the interaction of incentives, lying aversion, and preferences for payoff distributions. Finally, in line with previous findings, women are less likely to lie when it is costly to the other side. Interestingly though, we find that women are more likely to tell an altruistic lie.

Responsibility: The Tie that Binds
Cynthia Cryder & George Loewenstein
Journal of Experimental Social Psychology, forthcoming
Abstract:
People share significantly more money with others in common lab paradigms like the dictator game than they do in real life. What accounts for this difference? Paradigms like the dictator game link each recipient to a single dictator with the implication that each recipient can receive funds from only one person. We argue that this "burden" of responsibility to a single recipient helps to explain high levels of laboratory sharing. In two experiments - a modified dictator game experiment and a charitable giving experiment - participants donated significantly more to others when they were solely responsible for a recipient's outcome than when the responsibility for a recipient was potentially shared. Taken together with past findings from social psychology and experimental economics, the results show how unambiguous responsibility for a single recipient increases generosity.

Developmental Psychology, forthcoming
Abstract:
When people reflect on their important values, they may become more attuned to the needs of others. Two longitudinal field experiments examined whether a subtle value-affirmation manipulation can initiate relatively enduring increases in young adolescents' prosocial feelings (Study 1; Mage = 12.9) and prosocial behaviors (Study 2; Mage = 12.9). Participants completed a brief writing exercise that affirmed the values they deemed either most important (value-affirmation group) or unimportant (control group). As predicted, the value affirmation, coupled with a booster affirmation 6 weeks later, caused increases in prosocial feelings and behaviors over the 3-month study period. Antisocial students who were value-affirmed showed especially strong increases in prosocial behavior. These results suggest that "gentle passions" can be aroused in youth by cost- and time-efficient means. The practical utility of value affirmations will need to be evaluated in future work.

Practicing Compassion Increases Happiness and Self-Esteem
Myriam Mongrain, Jacqueline Chin & Leah Shapira
Journal of Happiness Studies, December 2011, Pages 963-981
Abstract:
The current study examined the effect of practicing compassion towards others over a 1 week period. Participants (N = 719) were recruited online, and were assigned to a compassionate action condition or a control condition which involved writing about an early memory. Multilevel modeling revealed that those in the compassionate action condition showed sustained gains in happiness (SHI; Seligman et al. in Am Psychol 60:410-421, 2005) and self-esteem (RSES; Rosenberg in Society and the adolescent self-image. Princeton University Press, Princeton, 1965) over 6 months, relative to those in the control condition. Furthermore, a multiple regression indicated that anxiously attached individuals (ECR; Brennan et al. 1998) in the compassionate action condition reported greater decreases in depressive symptoms following the exercise period. These results suggest that practicing compassion can provide lasting improvements in happiness and self-esteem, and may be beneficial for anxious individuals in the short run.

Where do human organs come from? Trends of generalized and restricted altruism in organ donations
Hagai Boas
Social Science & Medicine, November 2011, Pages 1378-1385
Abstract:
The supply of human organs for transplantation is undergoing a dramatic transformation. Using data from 30 countries for the years 1995-2007, this paper suggests that organ supply today is more dependent on direct donations than on the collective organ pool. This trend is analyzed by studying different modes of altruism: "generalized altruism" relates to the procurement of organs through a one-for-all collectivized system of donations whereas "restricted altruism" relates to one-to-one donations with organs considered personal gifts. The data suggest that transplants are becoming less and less social goods and more and more personal gifts. This trend is documented and discussed in light of the linkage that social scientists hypothesize between altruism and social solidarity. Whereas altruism is conceived as generating social solidarity, the rise in direct organ donations restricts the effect of altruism to one-to-one interactions rather than one-for-all giving.

Anonymity in the Dictator Game Revisited
Axel Franzen & Sonja Pointner
Journal of Economic Behavior & Organization, January 2012, Pages 74-81
Abstract:
Giving in the dictator game has often been interpreted as evidence of other-regarding preferences. We suspect that giving is determined by subjects' attempts to appear fair in the eyes of recipients and the experimenter. Therefore, we investigate behavior in the dictator game by using the randomized response technique to increase anonymity. Overall, 290 subjects participated in two experiments. The results demonstrate that the randomized response technique reduces giving to negligible amounts compared to the standard double blind condition. Thus, our results suggest that individuals closely follow egoistic motives in the dictator game when anonymity is convincingly implemented.

Intermediation Reduces Punishment (and Reward)
Lucas Coffman
American Economic Journal: Microeconomics, November 2011, Pages 77-106
Abstract:
This paper shows moral decision making is not well predicted by the overall fairness of an act but rather by the fairness of the consequences that follow directly. In laboratory experiments, third-party punishment for keeping money from a poorer player decreases when an intermediary actor is included in the transaction. This is true for completely passive intermediaries, even though intermediation decreases the payout of the poorest player and hurts equity, and because intermediation distances the transgressor from the outcome. A separate study shows rewards of charitable giving decrease when the saliency of an intermediary is increased.

Active Decisions and Prosocial Behaviour: A Field Experiment on Blood Donation
Alois Stutzer, Lorenz Goette & Michael Zehnder
Economic Journal, November 2011, Pages F476-F493
Abstract:
Assigning a subjective value to a contribution to a public good often requires reflection. For many reasons, this reflection may be put off, reinforcing the underprovision of public goods. We hypothesise that nudging individuals to reflect on whether to contribute to a public good leads to the formation of issue-specific altruistic preferences. The hypothesis is tested in a large-scale field experiment on blood donations. We find that an 'active-decision' intervention substantially increases donations among subjects who had not previously thought about the importance of donating blood. By contrast, contributions of individuals who had previously engaged in such reflection are unchanged.

Paying to Be Nice: Consistency and Costly Prosocial Behavior
Ayelet Gneezy et al.
Management Science, forthcoming
Abstract:
Building on previous research in economics and psychology, we propose that the costliness of initial prosocial behavior positively influences whether that behavior leads to consistent future behaviors. We suggest that costly prosocial behaviors serve as a signal of prosocial identity and that people subsequently behave in line with that self-perception. In contrast, costless prosocial acts do not signal much about one's prosocial identity, so subsequent behavior is less likely to be consistent and may even show the reductions in prosocial behavior associated with licensing. The results of a laboratory experiment and a large field experiment converge to support our account.

The Evolution of Giving, Sharing, and Lotteries
Daniel Nettle et al.
Current Anthropology, October 2011, Pages 747-756
Abstract:
A core feature of human societies is that people often transfer resources to others. Such transfers can be governed by several different mechanisms, such as gift giving, communal sharing, or lottery-type arrangements. We present a simple model of the circumstances under which each of these three forms of transfer would be expected to evolve through direct fitness benefits. We show that in general, individuals should favor transferring some of their resources to others when there is a fitness payoff to having social partners and/or where there are costs to keeping control of resources. Our model thus integrates models of cooperation through interdependence with tolerated theft models of sharing. We also show, by extending the HAWK-DOVE model of animal conflict, that communal sharing can be an adaptive strategy where returns to consumption are diminishing and lottery-type arrangements can be adaptive where returns to consumption are increasing. We relate these findings to the observed diversity in human resource-transfer processes and preferences and discuss limitations of the model.

The Hidden Benefits of Control: Evidence from a Natural Field Experiment
Craig Landry et al.
NBER Working Paper, September 2011
Abstract:
An important dialogue between theorists and experimentalists over the past few decades has raised the study of the interaction of psychological and economic incentives from academic curiosity to a bona fide academic field. One recent area of study within this genre that has sparked interest and debate revolves around the "hidden costs" of conditional incentives. This study overlays randomization on a naturally-occurring environment in a series of temporally-linked field experiments to advance our understanding of the economics of charity and test if such "costs" exist in the field. This approach permits us to examine why people initially give to charities, and what factors keep them committed to the cause. Several key findings emerge. First, there are hidden benefits of conditional incentives that would have gone undetected had we maintained a static theory and an experimental design that focused on short run substitution effects rather than dynamic interactions. Second, we can reject the pure altruism model of giving. Third, we find that public good provision is maximized in both the short and long run by using conditional, rather than unconditional, incentives.

Fairness Expectations and Altruistic Sharing in 15-Month-Old Human Infants
Marco Schmidt & Jessica Sommerville
PLoS ONE, October 2011, e23223
Abstract:
Human cooperation is a key driving force behind the evolutionary success of our hominin lineage. At the proximate level, biologists and social scientists have identified other-regarding preferences - such as fairness based on egalitarian motives, and altruism - as likely candidates for fostering large-scale cooperation. A critical question concerns the ontogenetic origins of these constituents of cooperative behavior, as well as whether they emerge independently or in an interrelated fashion. The answer to this question will shed light on the interdisciplinary debate regarding the significance of such preferences for explaining how humans become such cooperative beings. We investigated 15-month-old infants' sensitivity to fairness, and their altruistic behavior, assessed via infants' reactions to a third-party resource distribution task, and via a sharing task. Our results challenge current models of the development of fairness and altruism in two ways. First, in contrast to past work suggesting that fairness and altruism may not emerge until early to mid-childhood, 15-month-old infants are sensitive to fairness and can engage in altruistic sharing. Second, infants' degree of sensitivity to fairness as a third-party observer was related to whether they shared toys altruistically or selfishly, indicating that moral evaluations and prosocial behavior are heavily interconnected from early in development. Our results present the first evidence that the roots of a basic sense of fairness and altruism can be found in infancy, and that these other-regarding preferences develop in a parallel and interwoven fashion. These findings support arguments for an evolutionary basis - most likely in dialectical manner including both biological and cultural mechanisms - of human egalitarianism given the rapidly developing nature of other-regarding preferences and their role in the evolution of human-specific forms of cooperation. Future work of this kind will help determine to what extent uniquely human sociality and morality depend on other-regarding preferences emerging early in life.

The impact of excess choice on deferment of decisions to volunteer
Lauren Carroll, Mathew White & Sabine Pahl
Judgment and Decision Making, October 2011, Pages 629-637
Abstract:
Excess choice has previously been shown to have detrimental effects on decisions about consumer products. As the number of options increases, people are more likely to put off making an active choice (i.e., defer) and show less satisfaction with any purchase actually made. We extend this line of enquiry to choosing a charitable organisation to volunteer for. The issue is important because the number of voluntary organisations is enormous and the impact of such a decision may be greater than for consumer decisions in terms of time commitment and benefits to the volunteer and society. Study 1 asked students to examine a real volunteering website and record how many organisations they considered, decision difficulty and whether or not they would like to sign up for a chosen organisation or prefer to defer a decision. Study 2 presented either a relatively small (10) or large (30) choice set of hypothetical organisations and measured deferment likelihood and decision difficulty. In both studies the more options considered, the greater the likelihood to defer. This effect was mediated by decision difficulty. This research is the first to find that detrimental effects of excess choice extend to volunteering. Implications for volunteer recruitment are discussed.

Insensitivity to social reputation in autism
Keise Izuma et al.
Proceedings of the National Academy of Sciences, 18 October 2011, Pages 17302-17307
Abstract:
People act more prosocially when they know they are watched by others, an everyday observation borne out by studies from behavioral economics, social psychology, and cognitive neuroscience. This effect is thought to be mediated by the incentive to improve one's social reputation, a specific and possibly uniquely human motivation that depends on our ability to represent what other people think of us. Here we tested the hypothesis that social reputation effects are selectively impaired in autism, a developmental disorder characterized in part by impairments in reciprocal social interactions but whose underlying cognitive causes remain elusive. When asked to make real charitable donations in the presence or absence of an observer, matched healthy controls donated significantly more in the observer's presence than absence, replicating prior work. By contrast, people with high-functioning autism were not influenced by the presence of an observer at all in this task. However, both groups performed significantly better on a continuous performance task in the presence of an observer, suggesting intact general social facilitation in autism. The results argue that people with autism lack the ability to take into consideration what others think of them and provide further support for specialized neural systems mediating the effects of social reputation.

The neural basis for establishing a focal point in pure coordination games
Corey McMillan et al.
Social Cognitive and Affective Neuroscience, forthcoming
Abstract:
When making a decision, humans often have to 'coordinate' - reach the same conclusion - as another individual without explicitly communicating. Relatively, little is known about the neural basis for coordination. Moreover, previous fMRI investigations have supported conflicting hypotheses. One account proposes that individuals coordinate using a 'gut feeling' and that this is supported by insula recruitment. Another account proposes that individuals recruit strategic decision-making mechanisms in prefrontal cortex in order to coordinate. We investigate the neural basis for coordination in individuals with behavioral-variant frontotemporal dementia (bvFTD) who have limitations in social decision-making associated with disease in prefrontal cortex. We demonstrate that bvFTD are impaired at establishing a focal point in a semantic task (e.g. 'Tell me any boy's name') that requires coordination relative to a similar, control semantic task that does not. Additionally, coordination limitations in bvFTD are related to cortical thinning in prefrontal cortex. These findings are consistent with behavioral economic models proposing that, beyond a 'gut feeling', strategic decision-making contributes to the coordination process, including a probabilistic mechanism that evaluates the salience of a response (e.g. is 'John' a frequent boy's name), a hierarchical mechanism that iteratively models an opponent's likely response and a mechanism involved in social perspective taking.

Heterogeneous preferences for altruism: Gender and personality, social status, giving and taking
Michael Visser & Matthew Roelofs
Experimental Economics, November 2011, Pages 490-506
Abstract:
Some of the earliest work on heterogeneity in social preferences focuses on gender differences in behavior. The source of these gender differences is the main interest of this paper. We report on dictator game experiments designed to identify heterogeneity of other-regarding preferences according to personality, gender, status, and whether the choice is framed as giving or taking. We find that the effect of gender on giving is more subtle than previously understood, and is explained collectively by various personality factors. We also find that women, high status treatment individuals, and individuals in the giving language treatment give less, and are also less sensitive to the price of giving.

Personality accounts for stable preferences and expectations across a range of simple games
Sean Brocklebank, Gary Lewis & Timothy Bates
Personality and Individual Differences, December 2011, Pages 881-886
Abstract:
Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players' choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of "prosocial orientation", measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors.

Do people with food service experience tip better?
Matt Parrett
Journal of Socio-Economics, October 2011, Pages 464-471
Abstract:
To the extent servers can establish an interpersonal connection with the customer, they can earn higher tips. One source of interpersonal connection between the server and the customer is interpersonal similarity, in the form of food service experience. Research by social scientists, combined with casual empiricism, suggests that customers with food service experience tip better than customers without food service experience. Using survey data collected outside of five Richmond, Virginia restaurants, we test this. Our findings, which are robust across a variety of empirical specifications, indicate that the former tip between 4 and 5% more than the latter.
