The Johari Window is a visual framework for understanding your conscious and unconscious biases. It is a tool that helps you know yourself, how people see you, relationship dynamics, and your blind spots. It was invented in the 1950s as a tool for mapping personality awareness. The Johari Window was created by two psychologists, Joseph Luft and Harrington Ingham. The name Johari is derived from the combination of the first names of the creators: Joseph and Harrington.

The model is a 2×2 grid, which represents things that a person knows about themselves on one axis and things that others know about them on the other axis. By plotting the levels of self-knowledge and the knowledge held by others, the person can develop a greater understanding of their personality and how others perceive them.
