The Johari Window was invented by Joseph Luft and Harrington Ingham in the 1950s as a model for mapping personality awareness. By describing yourself from a fixed list of adjectives, then asking your friends and colleagues to describe you from the same list, a grid of overlap and difference can be built up.
This is an interactive website that can be used to highlight personality differences using the Johari window. Users are asked to pick no more than six words to describe themselves; this is then saved under a name a specified of the profile. The next step is to have friends supply up to six words which are entered into the site. Differences are illustrated and produced in a document that can be downloaded.
