A considerable body of research in behavioural economics has established the existence of ambiguity avoidance: the tendency for people, when given a choice between two options, to choose the option for which there is greater certainty about the probabilities of certain outcomes occurring. In a seminal study, Curley, Yates, and Abrams (1986) explored potential psychological explanations of ambiguity avoidance, contrasting five hypotheses: hostile nature (the anticipation that more ambiguous options are biased against oneself), other-evaluation (the anticipation that one’s decision will be evaluated by others), self-evaluation (the anticipation that one's decision will be self-evaluated in the future), forced-choice (in which the less ambiguous option is selected only when all other considerations are equal), and a more general uncertainty avoidance associated with risk aversion. The results favoured other-evaluation as the most promising explanation, with implications in the following decades for research in social psychology, judgment and decision making, behavioural economics, consumer behaviour, and cognitive psychology.

 

In the current study, Yiu and Feldman (2022) plan to revisit the psychological basis of ambiguity avoidance in a large online sample through a replication of key studies from Curley et al. (1986), including extensions to increase methodological rigour and to explore the relationship between ambiguity avoidance and hostility bias, anticipated future regret, and post-choice social judgment from others, as well as trait measures of risk tolerance and ambiguity tolerance.

 

The Stage 1 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

 

 

Level of bias control achieved: Level 6. No part of the data or evidence that will be used to answer the research question yet exists and no part will be generated until after IPA.
