Regret is a powerful emotion. We don't want to feel regret and seek to avoid it. We not only can feel regret after making a choice, regret that we did not choose what might have been a better option, but we are capable of forecasting our future regret and of taking action now to avoid future regret for not acting. Of course, pursuing an option because we anticipate regret if we don't act does not assure that the choice we make is a "good" risk. Properly assessing the risk and potential return of an option and and whether we act on the option are separable activities. So if regret can get us off dead center and lead us to act, it does not remedy how our mental biases, shortcuts and errors hinder clear-eyed risk assessment.
