Domain-based asymmetry in expectations of the future

Area of Science:

• Cognitive Psychology
• Behavioral Economics
• Decision Science

Background:

• Prior outcomes significantly influence expectations regarding future events.
• The affect literature suggests positive outcomes lead to more optimistic expectations than negative outcomes.

Purpose of the Study:

• To investigate how the valence and domain of prior outcomes affect expectations about unrelated future events.
• To test the hypothesis that the impact of prior outcomes on future expectations is greater in the domain of losses than gains, drawing from Prospect Theory.

Main Methods:

• Conducted three experiments utilizing lottery-based scenarios.
• Manipulated the valence (positive/negative) and domain (gains/losses) of prior outcomes.
• Measured subsequent expectations and risk preferences.

Main Results:

• Prior positive outcomes led to more optimistic expectations compared to negative outcomes.
• The influence of prior outcomes on expectations was significantly stronger in the domain of losses than in the domain of gains.
• These expectation differences correlated with variations in risk preferences.

Conclusions:

• Prior outcomes exert a dual influence on future expectations, mediated by both valence and domain.
• Prospect Theory's principles effectively predict how loss aversion amplifies the impact of prior negative outcomes on future expectations and risk-taking.
• Understanding these psychological mechanisms is crucial for fields ranging from behavioral finance to personal decision-making.
