Predictably intransitive preferences
Journal Title: Judgment and Decision Making - Year 2018, Vol 13, Issue 3
Abstract
The transitivity axiom is common to nearly all descriptive and normative utility theories of choice under risk. Contrary to both intuition and common assumption, the little-known ’Steinhaus-Trybula paradox’ shows the relation ’stochastically greater than’ will not always be transitive, in contradiction of Weak Stochastic Transitivity. We bespoke-design pairs of lotteries inspired by the paradox, over which individual preferences might cycle. We run an experiment to look for evidence of cycles, and violations of expansion/contraction consistency between choice sets. Even after considering possible stochastic but transitive explanations, we show that cycles can be the modal preference pattern over these simple lotteries, and we find systematic violations of expansion/contraction consistency.

Learning to communicate risk information in groups
Despite vigorous research on risk communication, little is known about the social forces that drive these choices. Erev, Wallsten, & Neal (1991) showed that forecasters learn to select verbal or numerical probability est...
Do we de-bias ourselves?: The impact of repeated presentation on the bat-and-ball problem
The notorious bat-and-ball problem has long been used to demonstrate that people are easily biased by their intuitions. In this paper we test the robustness of biased responding by examining how it is affected by repeate...

Individuals have been shown to adaptively select decision strategies depending on the environment structure. Two experiments extended this research to the group level. Subjects (N = 240) worked either individually or in...
