What you expect is not always what you get: The roles of extremity, optimism, and pessimism in the behavioral confirmation process

Do pessimists and optimists elicit the very behavior they expect from others? What if their expectations are fairly extreme? Using a simulated job interview paradigm, evidence was found for behavioral confirmation of generalized future-event expectancies (optimism/pessimism) and for the moderating role of extremity. Interviewers with nonextreme expectancies gathered information in an expectancy-biased fashion and elicited expectancy-confirming behavior from applicants. However, as interviewer expectancies became more extreme, these effects were attenuated. Further evidence suggested that extremity is associated with effortful correction processes and awareness of bias. Interestingly, pessimistic applicants were more strongly influenced by interviewers’ expectancies than were optimistic applicants. The current study extends research on the social-cognitive consequences of generalized future-event expectancies and extremity to the behavioral domain.
