Ratner and Kahn demonstrated that individuals believed that others would seek more variety than they themselves would seek. Building on this finding, we expected the variety-seeking tendency to be greater when people made choices for others, and we examined the mechanisms of this phenomenon. Study 1 explored an interpersonal mechanism and demonstrated that variety seeking for others became stronger when individuals were held accountable for...

Tested 3 hypotheses concerning people's predictions of task completion times: (1) people underestimate their own but not others' completion times, (2) people focus on plan-based scenarios rather than on relevant past experiences while generating their predictions, and (3) people's attributions diminish the relevance of past experiences. Five studies were conducted with a total of 465 undergraduates. Results support each hypothesis. Ss' predictions of their completion...

We hypothesized that people motivated to believe that they possess a given trait search for autobiographical memories that reflect that trait, so as to justify their desired self-view. We led subjects to believe that either extraversion or introversion was desirable, and obtained convergent evidence from open-ended memory-listing tasks as well as from reaction time (RT) tasks measuring the speed with which memories could be generated...

Previous research has demonstrated that people recall their past in ways that exaggerate its consistency with their current condition. It is argued that whether people perceive stability or change in themselves depends, in part, on the theory they invoke to reconstruct their past. Two studies, with 106 undergraduates, addressed the impact of a potentially invalid theory of change on the recall of personal histories. Some...

Using data from a panel survey of members of two generations, this study explores observed change in policy opinions across a 9-year span and respondents' recollections and explanations of their self-perceived attitude shifts. In general, remembrances corresponded poorly to opinions as originally expressed, with respondents perceiving that they were more attitudinally stable than was actually observed. When attempting to reconstruct their past political attitudes, individuals...

The hindsight bias is the tendency for people with outcome knowledge to believe falsely that they would have predicted the reported outcome of an event. This article reviews empirical research relevant to hindsight phenomena. The influence of outcome knowledge, termed creeping determinism, was initially hypothesized to result from the immediate and automatic integration of the outcome into a person's knowledge of an event. Later research...

Notes that a major difference between historical and nonhistorical judgment is that the historical judge typically knows how things turned out. 3 experiments are described with a total of 479 college students. In Exp I, receipt of such outcome knowledge was found to increase the postdicted likelihood of reported events and change the perceived relevance of event-deive data, regardless of the likelihood of the outcome...

Examined the self-fulfilling influences of social stereotypes on dyadic social interaction. Conceptual analysis suggests that a perceiver's actions based upon stereotype-generated attributions about a specific target individual may cause the behavior of that individual to confirm the perceiver's initially erroneous attributions. A paradigmatic investigation of the behavioral confirmation of stereotypes involving physical attractiveness (e.g., "beautiful people are good people") is presented. 51 male "perceivers" interacted...

Input from alien cultures might stimulate exceptional national achievements. This hypothesis was tested by applying generational time-series analysis to a society whose history shows tremendous variation in its receptiveness to the external world (viz., Japan between 580 and 1939). After required controls and data transformations were introduced, the cross-correlations were examined between 3 measures of extracultural influx (outside influence, travel abroad, and eminent immigrants) and...

Conducted a naturalistic study on Halloween to assess the effects of 3 deindividuation variables (anonymity vs nonanonymity, alone vs group, and groups with or without a child who was made responsible for the group's actions) on stealing by children. Concealed raters unobtrusively observed approximately 1,300 trick-or-treating children who were assigned to various conditions and given an opportunity to steal candy and money. Significantly more stealing...
