Do People Prescribe Optimism, Overoptimism, or Neither?

Area of Science:

• Cognitive Psychology
• Decision Making
• Social Psychology

Background:

• Previous research suggests people favor optimism over accuracy when anticipating uncertain future events.
• An ambiguity exists regarding whether these findings reflect a genuine endorsement of biased beliefs or overoptimism in likelihood estimations.

Purpose of the Study:

• To investigate whether people prescribe biased beliefs, specifically overoptimism, in likelihood estimations for uncertain future events.
• To clarify the nature of optimism prescription by examining different questioning methods.

Main Methods:

• Three studies were conducted with 663 U.S. university students.
• Participants evaluated scenarios involving protagonists facing uncertain events with desired outcomes.
• Different solicitations were used to assess optimism prescription, including those probing for bias and avoiding vague terms.

Main Results:

• Prescriptions of optimism were replicated using traditional questioning methods.
• Alternative methods, which questioned potential bias and avoided vague terms, yielded different results.
• Participants endorsed optimistic feelings and thinking but did not prescribe overestimating event likelihoods.

Conclusions:

• The findings suggest that while people generally favor optimistic outlooks, they do not necessarily prescribe biased overestimation of probabilities.
• The way questions are phrased significantly influences the perception and prescription of optimism.
• Clarifying the ambiguity around optimism prescription is crucial for understanding decision-making under uncertainty.
