Decision makers are frequently confronted with ambiguous risk information about activities with potential hazards. This may be a result of conflicting risk estimates from multiple sources or ambiguous risk information from a single source. The paper considers processing ambiguous risk information and its effect on the behavior of a decision maker with alpha-maximin expected utility preferences. The effect of imprecise risk information on behavior is related to the content of information, the decision maker's trust in different sources of information, and his or her aversion to ambiguity.
