The Forer effect doesn't necessarily require that everyone feels that a specific characterization applies to them: only that the person being characterized feels that that specific characterization applies to him. This is an important difference, because it allows astrologers, illusionists and their ilk to use all kinds of the usual psychological insights to determine broadly into which category someone falls, before coming up with a characterization that will necessarily be recognizable to someone in that category.
Anyone can put me in the INTJ, ENTP or the two intermediate categories. That's already 4 out of 16. Now collect some characteristics from those 4 and mingle: voila, you have produced something I will consider recognizable. In this way, everyone is as good a psychologist as Jung.
