George Kelly developed his personal construct theory while working as a clinical psychologist in rural Kansas in the 1930s. He found standard Freudian theories did not fit his clients' lives and experiences. Kelly realized his clients accepted any explanation from an authority figure that provided order and understanding. This led Kelly to develop his theory of personal construct psychology, which views people as actively anticipating and construing their experiences like scientists develop theories. Kelly organized his theory around a fundamental postulate that a person's thoughts and behaviors are shaped by their anticipations of events, and 11 corollaries about how experience changes a person's constructs and understanding of reality.
