We study “hypothetical reasoning” in games where the impact of risky prospects (chance moves with commonly-known conditional probabilities) is compounded by strategic uncertainty. We embed such games in an environment that permits us to verify if risk-taking behavior is affected by information that reduces the extent of strategic uncertainty. We then test some implications of expected utility theory, while making minimal assumptions about individuals’ (risk or ambiguity) attitudes. Results indicate an effect of the information on behavior: this effect is triggered in some cases by a belief-revision about others’ actions, and in other cases by a reversal in risk preferences.
