Johari window

The Johari window is a technique[1] designed to help people better understand their relationship with themselves and others.

It was created by psychologists Joseph Luft (1916–2014) and Harrington Ingham (1916–1995) in 1955, and is used primarily in self-help groups and corporate settings as a heuristic exercise.

In the exercise, someone picks a number of adjectives from a list, choosing ones they feel describe their own personality.

[4] In Inside Organizations: 21 Ideas for Managers (1990), Charles Handy calls this concept the Johari House with four rooms.

The participant can use adjectives like these as possible descriptions in the Johari window.
