4.26 / 5

LITBertram Forer (1949) gave 39 students a "personalised" personality sketch, in fact the same text for all, drawn mostly from a newsstand astrology book. They rated its accuracy at 4.26 out of 5 on average (as commonly reported). Vague, flattering, double-sided statements feel personal: the Barnum or Forer effect. It explains why numerology, palmistry and phrenology readings feel right.
