ABSTRACTIs the question ‘will you regret it if you do this?’ helpful when people face difficult life decisions, such as terminating a pregnancy if a disability is detected or deciding to become a parent? Despite the commonness of the question in daily life, several philosophers have argued lately against its usefulness. We reconstruct four arguments from recent literature on regret, transformative experience and the use of imagination in deliberation. After analysis of these arguments we conclude that the prospect of regret (...) remains a useful deliberative heuristic, provided four conditions are fulfilled. If the prospect of regret is arrived at via reflection on one’s values, in a non-coercive context, when well-informed about factual circumstances, and in a process of self-commitment, the question of what one will regret is a helpful device to get in touch with one’s deepest concerns that give reasons to act in a particular way.
