Development of the concept

Forer in 1948, who demonstrated the effect by giving a personality test to his students and then providing each of them with a personalized “analysis” of their personality traits. The analyses were identical for all students, but each student rated their own analysis as highly accurate. This experiment showed that people are willing to accept vague and general descriptions as being specifically true for them.
