Reasonable Man Theory Law and Legal Definition
Reasonable man theory refers to a test whereby a hypothetical person is used as a legal standard, especially to determine if someone acted with negligence. This hypothetical person referred to as the reasonable/prudent man exercises average care, skill, and judgment in conduct that society requires of its members for the protection of their own and of others' interests. This serves as a comparative standard for determining liability. For example, the decision whether an accused is guilty of a given offense might involve the application of an objective test in which the conduct of the accused is compared to that of a reasonable person under similar circumstances.
