Whilst Tversky and Kahneman acknowledge that heuristics can be quite useful, the focus of their article is the “severe and systematic errors” that heuristics lead to. I would be interested to know whether there are any cases where these cognitive biases/errors of judgement actually result in a more desirable outcome, be that at the individual- or societal-level (or both)? In other words, are there any instances where policymakers would want to encourage heuristic decision-making? If so, would this be acceptable, given that it would essentially involve nudging people in the opposite direction to that typically discussed?
