Ambiguity aversion refers to that people prefer events with known probabilities to similar ambiguous events where the decision maker does not know the values of the probabilities. Ambiguity aversion has been well-established in the field of behavioral decision making and verified across many different domains since it was first proposed by Ellsberg. This paper sorted out the research on ambiguity aversion over live decades, systematically analyzed the research paradigm, psychological mechanism and influential factors of ambiguity aversion. Finally, the directions for future study on ambiguity aversion were suggested.
