How can policymakers use the insights from the research on cognitive biases and heuristics to design more effective nudges? Are there certain biases or heuristics that are particularly amenable to nudging, and if so, what nudges have been shown to be most effective in overcoming these biases? What are some examples of nudges that have been informed by the research on cognitive biases and heuristics, and how have they been designed to target specific cognitive processes? Finally, what ethical considerations need to be taken into account when designing nudges that aim to overcome cognitive biases and heuristics, and how can policymakers ensure that nudges are used responsibly and effectively?
