I got 3 out of 7 right lol... Not as bad as I expected considering the fact that I'm not a professional astrologer and that I didn't have the results of the questionnaire on my hands. It's funny that I gave first 3 charts the most thought and got them right but was less serious about the others and got them wrong. I'm kinda mad at myself now, I could've easily guessed the occupations of the 5th and 6th persons if I was more serious about it. Charts 4 and 7 are less conclusive to me so I could get them wrong anyway.
Would be interesting to see what score other people can get (no cheating, please!). It's pretty fun. Maybe we should try something similar on this site.
As for the test itself, I think it was performed well and the author doesn't seem very biased from the way he describes the process of it. The fact that he allowed the astrologers to ask the participants questions beforehand and was interested in their opinion of why they had such unsatisfying results shows that he was a good researcher and was willing to have the testing done correctly. The only conclusion I have is that most probably the majority of those people who claimed to be astrologers were either charlatans or totally sucked at their occupation. It truly boggles my mind that only one (!) astrologer out of 50 managed to get 3 correct matches and no one showed a better result than that. The possibility of getting 3 or more correct answers at random was about 6.5% and only 2% of participants managed to get into this zone, which means that they could obtain better results if they had nothing to do with astrology!
