Improving risky choices: The effect of cognitive offloading on risky decisions
研究提供外部工具以降低选择计算复杂度是否改善风险决策，发现人们很少使用这些工具，虽能降低风险厌恶和改善信念更新，但未能减少非理性行为。
Abstract Economic choices are difficult and computationally complex. To make good decisions one needs to integrate different variables and resolve several trade-offs. We study whether providing external tools which help reducing the computational complexity of choices improves risky decisions. We find mixed evidence for the effectiveness of these tools, as people tend to rarely use them. Overall, cognitive offloading tools make people less risk averse and better at updating beliefs, but they do not decrease irrational behavior, in the sense of the proportion of dominated choices, violations of expected utility, and sub-optimal budget allocations. These results suggest that simply providing external tools, which make choices (computationally) easier, but where using these aids is discretional, has a limited impact on improving people’s choices under risk.
