The Johari window is a technique designed in 1955 by American psychologists Luft and Ingham that is used to help people to better understand themselves and their relationship with others. It is normally used in self-help groups and corporate team-building settings. This technique starts with a 4-square matrix and a list of 56 adjectives from which an individual chooses 5 or 6 to describe themselves. These are then placed in categories as to whether they are traits known to self and others/known only to self/known only to others/unknown to self and others. Then other members of the individual's peer group choose adjectives from the same list to describe the first individual and these are also placed on the matrix. This exercise to meant to help an individual see themselves as others see them.
