Six astrologers, reputably very able, were given (a) natal charts (b) extensive files of the corresponding people, including results of personality tests, profession, CV (minus the birthdate), hobbies, photographs, recents traumatic events in personal life and so on. The number of natal charts was quite large and comprised a very diverse group of people. The only restriction was that they were about the same age (to make guessing from the photograph or CV difficult). The astrologers were to match them. Oral interview was not allowed. (self attribution of sun-sign properties is common, so any technique that would provoke such self-attribution is out. The subjects were not told that their form was going to be interpreted by an astrologer. The expected number of hits (matches is as follows). A chance of 1/e (37.8%) of scoring 0 hits. A chance of 1/e of scoring 1 hit A chance of 1/2e of scoring 2 hits A chance of 1/6e of scoring 3 hits A chance of 1/24e of scoring 4 hits And so on (above numbers apply to a sufficiently large sample, but from a sample of 8 on they are already good approximations. The average number of hits over many tries would be 1. The results: the six astrologers scored between 0 and 3 hits. The interpretations of the astrologers did not even correlate among themselves. The 15 ways of comparing one astrologer with the other yielded 21 hits. At the meeting of the Indiana astrologers where the results were made known, the members present were challenged to do better, but again they failed. What was the reaction of the astrologers (mind you, after extensively cooperating with the researchers, and indicating everything they might need to know about their `clients' and approving of the whole set-up): "Well it figures, this is the lost generation due to [unfavorable Pluto-Neptune conjunction or something like that]." In their report they managed to render the name of one of the reseachers completely wrong.
