Barnum Effect: To be seen as accurate, astrology and graphology do not have to be accurate. Instead, you simply give people a general statement about personality and their brains will trick them into believing that it is insightful and individual. In the 1950s, the psychologist Paul Meehl christened Forer’s original finding the “Barnum Effect”, after that American showman Phineas Taylor Barnum, who once famously said that any good circus should have something for everyone. Many Barnum statements appear accurate because most people tend to think and behave in surprisingly predictable ways. [From Quirkology]
