Probability weighting under time pressure: applying the double-response method

We conduct a laboratory experiment to investigate the impact of deliberation time on behavior under risk and uncertainty. Towards this end we let our participant make quick, intuitive evaluations of a number of lotteries and modify them, should they wish to do so, after deliberation. Both certainty equivalents are incentivized (a double-response method). The main finding is that additional deliberation time reduces pessimism, especially in the case of lotteries involving unknown probabilities.
