It was developed by American psychologists Joseph Luft and Harry Ingham , where Jo comes from Joseph and Hari from Harry. Though generally used in Management lessons to improve group and team interactions, I love it for its innovative and creative approach to self development. It is a model for self-awareness, personal development, group development and understanding relationships.
It is a window because of its design which is like a four paned window. And the regions are called the areas or Quadrants. Each contains and represents the information such as feelings, motivation, etc – in terms of whether the information is known or unknown by the person, and whether the information is known or unknown by others.
The first quadrant is the Open area, open self: what is known by us about ourselves and is also known by others about us – for e.g. name, qualifications etc.
The second quadrant is the Blind area, blind self, or 'blindspot‘: what is unknown by us about ourselves but which others know. For e,g, how we behave with others – something people observe but we ourselves may not be aware of.
The third quadrant is the Hidden area, hidden self: what we know about ourselves that others do not know. For e.g. our likes and dislikes about which we may not be very open.
The final quadrant is the Unknown area or unknown self: what is unknown by us about ourselves and is also unknown by others. For e.g. Our potential
As is clear, we should make efforts in quadrant 2 – as this is something which others know about us – How ? – take feedback from persons closest to you. Let them tell you honestly about what they think about you. That will give a very good idea on how to improve yourself.
It is also important to reduce the Hidden area (quadrant 3) about yourself – meaning if you are hiding things from your friends and family – it is bound to create trouble sooner or later. It is important to be honest in your relationships.
If you are able to manage the above two – the last quadrant will automatically sort itself out.
So, what are you waiting for? Good Luck !
