Basic Postulate of Kelly's Personal Construct Theory

"A person's processes are psychologically channelized by the ways in which he anticipates events"

George Kelly, The Psychology of Personal Constructs, page 46


As presented in Jess Feist's Theories of Personality, pages 587, 588

  1. Construction Corollary. We anticipate future events according to our interpretations of recurrent themes.
  2. Individuality Corollary. People have different experiences and therefore construe events in different ways.
  3. Organization Corollary. We organize our personal contructs in a hierarchical system, with some constructs in a superordinate position and others subordinate to them. This organization allows us to minimize incompatible contructs.
  4. Dichotomy Corollary. All personal constructs are dichotomous, that is, we construe events in an either/or manner.
  5. Choice Corollary. We choose the alternative in a dichotomized construct that we see as extending our range of future choices.
  6. Range Corollary. Constructs are limited to a particular range of convenience, that is, they are not relevant to all situations.
  7. Experience Corollary. We continually revise our personal constructs as the result of experience.
  8. Modulation Corollary. Not all new experiences lead to a revision of personal constructs. To the extent that constructs are permeable they are subject to change through experience. Concrete or impermeable constructs resist modification regardless of our experience.
  9. Fragmentation Corollary. Our behavior is sometimes inconsistent because our construct system can readily admit incompatible elements.
  10. Commonality Corollary. To the extent that we have had experiences similar to others, our personal contructs tend to be similar to the construction systems of those people.
  11. Sociality Corollary. We are able to communicate with others because we can construe their constructions. We not only observe the behavior of others, but we also interpret what that behavior means to them.
