Johari window

A Johari window is a psychological tool created by Joseph Luft and Harry Ingham in 1955 in the United States.

It was developed while researching group dynamics.

Today the JW model is especially relevant because of the modern emphasis on soft skills, behavior, empathy, cooperation, inter-group development and interpersonal development.

Arena
What is known by the person about him/herself and also known by others.
Examples: your name, the color of your hair, the fact you own a car.

Blind Spot
What is unknown by the person about him/herself but what others know.
Examples: your own manners, the feelings of other persons about you.

Facade
What the person knows about him/herself that others do not know.
Such as: your secrets, your hopes, desires, what you like and what you dislike.

The Unknown
Traits unknown by the person about him/herself and also unknown by others.
The unknown also has potential to influence the rest of the JW.
