"George Kelly's 'repertory grid' is one of a number of tricks for bringing to the surface of our minds, and to the forefront of awareness, things we did not know we knew.... We learn about our own beliefs, wishes or habits; and in the process of pondering them they are changed. Other such techniques include the I Ching, astrology, art therapy and studying the entrails of chickens."
