Johari window.

​The Johari window concept was developed by American psychologists Joseph Luft and Harry Ingham in the 1950s, and it's becoming increasingly relevant today.

The Johari window concept is sometimes referred to as a self-awareness disclosure and feedback model. The Johari window is essentially a tool for processing information, but it's also a great way to look at how people can be affected by their thoughts and actions.

In terms of self-awareness, we all have blind spots—things about ourselves that we don't see or understand. These blind spots make us human, but they can also make it difficult for us to grow in certain areas. The Johari window helps us recognize these blind spots and develop strategies for overcoming them.

The Johari window concept is based on the idea that people have different levels of self-awareness and can be classified into four groups:

1) Open (things known by self and others),

2) Blind (things known by others but unknown by self),

3) Hidden / Facade (things known by self but unknown by others), and

4) Unknown (things not known by either self or others).

Most communication takes place in the open area, meaning we share our thoughts and feelings with other people. As this area gets bigger, our relationships become more involved and meaningful. The "feedback solicitation" process involves understanding and paying attention to another person's insight to reduce our blind spot. By doing so, we can increase our open area horizontally while also sharing our thoughts and feelings with another person to reduce their hidden area. By sharing one's thoughts and feelings with another person, one can expand the open size by eliminating hidden parts. I have always been a fan of this model.
