Consciously stochastic in preference reversals

Abstract

AbstractStochastic choice, the act of choosing differently in repeated decisions, can be a conscious decision made by individuals who are aware of their inability to make a definitive choice. To examine the prevalence and implications of conscious stochastic choice, we developed a novel method and implemented it in a preference reversal experiment: In each valuation choice between the bet and a varying reference option, subjects could either pay a small cost to select a specific option or opt for a free randomization choice where a computer randomly selects an option. Our findings revealed that the majority of subjects exhibited conscious stochastic choice, and further that their choices were significantly affected by the elicitation procedures.
