Origin
Psychologist Bertram Forer originally called it the "fallacy of personal validation" in his 1949 paper. In a 1948 experiment, Forer gave students identical personality analyses stitched from horoscopes; they rated them 4.26/5 despite the generic content. Psychologist Paul E. Meehl coined "Barnum effect" in 1956, naming it after showman P.T. Barnum. Subjective validation is the broader phenomenon of attributing personal relevance to generic statements.
