The Reasonable Person Standard: Psychological and Legal Perspectives

In criminal cases of self-defense and provocation, and civil cases of negligence, culpability is often decided with reference to how a reasonably prudent person (RPP) would have behaved in similar circumstances. The RPP is said to be an objective standard in that it eschews consideration of a defendant's unique background or characteristics. We discuss theory and evidence suggesting that in morally relevant judgments, including those involving negligence, self-defense, and provocation, the tendency to rely on the self—on one's own values and predilections—dominates considerations of the RPP. We consider subjective standards that have been proposed as alternatives to the RPP and review research on this topic. We conclude by considering avenues for future research, particularly addressing conditions in which self-standards of reasonableness are most likely to prevail.
