Dass Denken und Handeln nicht übereinstimmen wird ja oft als schlecht gebrandmarkt, leider ist es aber auch so, dass Denken und Handeln sich nicht selten unheilvoll miteinander verbünden.

Ein Zitat von George Kelley, The Psychology of Personal Constructs. New York (S. 12 f.):

A man construes his neighbor’s behavior as hostile. By that he means that his neighbor, given the proper opportunity, will do him harm. He tries out his construction of his neighbor’s attitute by throwing rocks at his neighbor’s dog. His neighbor responds with an angry rebuke. The man may then believe that he has validated his construction of his neighbor as a hostile person.
