Reasonable person model

The reasonable person model (RPM) is a psychological framework which argues that people are at their best when their informational needs are met. Positing that unreasonableness is not a human trait, but rather the result of environment (context and circumstances), the RPM attempts to define the environments/actions that foster reasonableness, defining three key areas that assist with this: model building, being effective, and meaningful action.

The RPM was developed by environmental psychologists Stephen and Rachel Kaplan and integrates principles from environmental, cognitive, and evolutionary psychology.
