Easier than arguing about Astrology is to test claims made by astrologers. In a recent thread, after some effort, a visiting astrologer to this site made the claim that:

Below are a growing collections of articles & sites addressing this claim. Please let me know of more sites.

Researchers looked at more than 100 different characteristics, including occupation, anxiety levels, marital status, aggressiveness, sociability, IQ levels and ability in art, sport, mathematics and reading – all of which astrologers claim can be gauged from birth charts.
