When guessing what another person would say is better than giving your own opinion: Using perspective-taking to improve advice-taking

We investigated how perspective-taking might be used to overcome bias and improve advice-based judgments. Decision makers often tend to underweight the opinions of others relative to their own, and thus fail to exploit the wisdom of others. We tested the idea that decision makers taking the perspective of another person engage a less egocentric mode of processing of advisory opinions and thereby improve their accuracy. In Studies 1–2, participants gave their initial opinions and then considered a sample of advisory opinions in two conditions. In one condition (self-perspective), they were asked to give their best advice-based estimates. In the second (other-perspective), they were asked to give advice-based estimates from the perspective of another judge. The dependent variables were the participants' accuracy and indices that traced their judgment policy. In the self-perspective condition participants adhered to their initial opinions, whereas in the other-perspective condition they were far less egocentric, weighted the available opinions more equally and produced more accurate estimates. In Study 3, initial estimates were not elicited, yet the data patterns were consistent with these conclusions. All the studies suggest that switching perspectives allows decision makers to generate advice-based judgments that are superior to those they would otherwise have produced. We discuss the merits of perspective-taking as a procedure for correcting bias, suggesting that it is theoretically justifiable, practicable, and effective.     

The ‘Right’ Side of Creativity: Creative Personality and Social Risk-Taking Predict Political Party Affiliation

Factors that predict political party affiliation are of particular importance in research due to the wider implications in politics and policy making. Extending this line of work, the idea that creativity predicts party affiliation was tested using 2 conceptualizations of creativity: creative personality and creative ideation. Participants (N = 406) based in the United States completed measures of creativity, socio-political attitudes, and domain specific risk-taking, and indicated their party affiliation. Results revealed a significant link between creative personality and political party affiliation. Furthermore, in addition to the socio-political attitudes, this link was explained, in part, by individuals’ social risk-taking. Specifically, individuals with higher scores on creative personality were more likely to affiliate to the Democratic party, whereas the reverse was true for affiliation to the Republican party. This article provides new insights into factors that predict political party affiliation and presents wider social implications of the findings.     

Adapted to explore: Reinforcement learning in Autistic Spectrum Conditions

Recent studies have recorded a tendency of individuals with Autism Spectrum Conditions (ASC) to continually change their choices in repeated choice tasks. In the current study we examine if this finding implies that ASC individuals have a cognitive style that facilitates exploration and discovery. Six decision tasks were administered to adolescents with ASC and matched controls. Significant differences in shifting between choice options appeared in the Iowa Gambling task (Bechara, Damasio, Damasio, & Anderson, 1994). A formal cognitive modeling analysis demonstrated that for about half of the ASC participants the adaptation process did not conform to the standard reinforcement learning model. These individuals were only coarsely affected by choice-outcomes, and were more influenced by the exploratory value of choices, being attracted to previously un-explored alternatives. An examination of the five simpler decision tasks where the advantageous option was easier to determine showed no evidence of this pattern, suggesting that the shifting choice pattern is not an uncontrollable tendency independent of task outcomes. These findings suggest that ASC individuals have a unique adaptive learning style, which may be beneficial is some learning environment but maladaptive in others, particularly in social contexts.     

Being Clean and Acting Dirty: The Paradoxical Effect of Self-Cleansing

In two studies we investigated the association between physical cleansing and moral and immoral behavior in real-life situations. In Study 1, after a workout at the gym, participants cheated more after taking a shower than before taking one. In the second study, participants donated more money to charity before rather than after they bathed for religious purification. The results extend previous findings about moral cleansing and moral licensing and are discussed within the framework of conceptual metaphor theory.     

Overconfidence in interval estimates: What does expertise buy you?

People’s 90% subjective confidence intervals typically contain the true value about 50% of the time, indicating extreme overconfidence. Previous results have been mixed regarding whether experts are as overconfident as novices. Experiment 1 examined interval estimates from information technology (IT) professionals and UC San Diego (UCSD) students about both the IT industry and UCSD. This within-subjects experiment showed that experts and novices were about equally overconfident. Experts reported intervals that had midpoints closer to the true value—which increased hit rate—and that were narrower (i.e., more informative)—which decreased hit rate. The net effect was no change in hit rate and overconfidence. Experiment 2 showed that both experts and novices mistakenly expected experts to be much less overconfident than novices, but they correctly predicted that experts would provide narrower intervals with midpoints closer to the truth. Decisions about whether to consult experts should be based on which aspects of performance are desired.     

A comparison of the risk‐taking behaviors of prisoners and non‐prisoners

Do prisoners and non‐prisoners differ in their risk‐taking behavior and the domains where they take risks? Surprisingly little psychological research has addressed these questions, despite the well‐established paradigms and extensive literature on risk taking among non‐prison populations. To fill this gap, we used the Domain‐Specific Risk‐Taking Scale to compare 75 male prisoners' and 75 male non‐prisoners' risk‐taking behavior, risk perception, and risk benefit in five domains (ethical, financial, health, recreational, and social). Our results show that prisoners and non‐prisoners did not differ in their risk‐taking behavior in the ethical, financial, recreational, or social domains. In the health domain, however, prisoners exhibited significantly higher risk‐taking tendencies. With regard to risk perception, prisoners perceived activities as significantly more risky than non‐prisoners, aside from the financial domain where non‐prisoners reported significantly higher risk perception. In all five domains, prisoners perceived risk‐taking activities as offering fewer benefits compared to the non‐prisoner sample. Our results also indicate that risk‐taking activities are better predicted by the expected benefits than by risk perception for both prisoners and non‐prisoners in the recreational, financial, and ethical domains. However, for prisoners, risk taking in the social domain increased with level of perceived benefit. In the health domain, prisoners' risk taking decreased with increasing level of perceived risk, whereas for non‐prisoners, perceived benefits, but not risk perception, predicted risk taking.

Receiving advice on matters of taste: Similarity, majority influence, and taste discrimination

People routinely consider the opinions of others prior to making decisions on matters of taste (e.g., a restaurant or movie). Our theoretical framework highlights the role of two sources, social (majority) influence and similarityamong advisors, in such decisions. We suggest that individuals’ use of these sources depends on their taste discrimination. While highly discriminating judges seek the opinion of a similar advisor rather than the majority opinion, less discriminating judges do so less. In four studies participants made musical choices based on recommendations. The studies document the great appeal of behavioral similarity and the role of demographic similarity. They also provide evidence for the discrimination hypothesis. A formal simulation is developed to account for the relationship between taste discrimination and the predictive accuracy of the majority and of similar advisors. The results shed light on theories of advice utilization and social influence, and are connected with applications involving personalized recommendation systems.     

Rate it again: Using the wisdom of many to improve performance evaluations

Much research shows that judgmental estimation could be improved by combining estimates from independent judges as well as within judges. These results have been obtained mostly with judgments about matters of fact, that is, for which there are objective truth criteria. In the present research, we extend these findings to performance evaluations. In a controlled field study, expert judges provided evaluations of a large number of essays written by college applicants taking college entrance tests. The judges were asked to evaluate each essay twice—on two occasions, a week apart. This design allowed us to assess the benefits of two methods of combining evaluations: within rater and across raters. Accuracy gains were obtained with both methods. Although the within‐rater combinations yielded fewer gains than the across‐rater ones, they were still appreciable in comparison with the across rater ones. Our findings extend the class of judgments to which the “wisdom of many” could be applied. These findings are potentially applicable to performance evaluations in social, educational, and employment settings.     

Advice Taking in Decision Making: Egocentric Discounting and Reputation Formation

Our framework for understanding advice-taking in decision making rests on two theoretical concepts that motivate the studies and serve to explain the findings. The first is egocentric discounting of others' opinions and the second is reputation formation for advisors. Advice discounting is attributed to differential information, namely, the notion that decision makers have privileged access to their internal reasons for holding their own opinion, but not to the advisors' internal reasons. Reputation formation is related to the negativity effect in impression formation and to the trust asymmetry principle. In three studies we measured decision makers' weighting policy for advice and, in a fourth study, their willingness to pay for it. Briefly, we found that advice is discounted relative to one's own opinion, while advisors' reputations are rapidly formed and asymmetrically revised. The asymmetry implies that it may be easier for advisors to lose a good reputation than to gain one. The cognitive and social origins of these phenomena are considered.
