The Johari Window was developed by two psychologists, Joseph Luft and Harrington Ingham in the USA in the 1950’s.
It is a combination of their two first names, Joe and Harry. I only found this out many years after I had first come across it, and it was a major disappointment to me, because I thought that Johari was some sort of Indian Maharajah and the window was a philosophical eye into a more spiritual and mystical world.
Despite its less than exotic origins I was drawn to it as I believe that it is a very useful tool for raising awareness of self and how our actions impact on others – and their actions on us. On the diagram you can see Four Panes (1, 2, 3 and 4) which I will describe in the following posts.
Here is the diagram – I have no source – I just Googled images of Johari Window. I think that it’s a fairly good representation. I don’t know where the diagram originated, i.e. who uploaded it. If the person who uploaded it is reading this please let me know so that I can credit you. Whoever or wherever you are – thanks!
You will see two dotted red lines, one vertical and one horizontal. These move (that’s why they are dotted) as we become more self-aware (or less, as the case may be) as will be explained in the following posts.

And I will include the diagram in each post so you won’t have to flick back to this post as you read about the different Panes!
