Motivating risky choices increases risk taking.

We study the impact of the mode of cognition on risk taking. In an online experiment we ask participants to make a simple decision involving risk. In the control group no manipulation is made, while in the treatment group we exogenously manipulate the mode of cognition by asking subjects to write down a text that motivates their risky choice before any decision is actually made. Such motivation treatment is meant to induce more reflection upon the decision to be made. Our results show an effect of the motivation treatment on risk taking, suggesting that higher reflection makes subjects more prone to risk taking. The effect is stronger if we consider only subjects who imperfectly understand the probability distribution implied by the simple choice task. Based on our experimental findings, we suggest that reflection and comprehension might be substitutes when individuals make decisions involving risk.
