Solving problems with an Aha! increases risk preference.

Solving problems with insight culminates in an " moment": a feeling of confidence and pleasure. In daily life, insights are often followed by important decisions, such as deciding what to do with a new idea. Here, we investigated whether having an Aha! moment affects subsequent decision-making. Because Aha! moments tend to elicit positive affect, which is generally associated with an increased risk-taking tendency, we hypothesized that people would favor a monetary payout with more upside despite greater uncertainty after solving a problem with insight. Participants were asked to solve verbal puzzles and report whether they solved them with insight or without insight. After each puzzle, they chose between two bonuses: a or a with 50% chance of receiving a high or a low payout. Participants were more likely to choose the risk payout after they solved with insight compared to without, suggesting a temporarily higher risk preference. The study provided preliminary evidence of a carryover effect - the impact of an Aha! moment on the subsequent risk choice - that can have implications in everyday decision-making.
