Vladimir Savchenko at Compatti.com makes some good points about the reliability of personality assesment tools.
Compatti.com’s compatibility assessment tool, which is based on biorhythms and astrology, is nearly 100%. It includes 3 simple questions: your date, place and time of birth.
I don’t buy the nearly 100% statement, but that aside, astrology is a generally useful meter for compatibility. Why don’t more sites take it seriously?
There was an article in the New Yorker last month? that discussed the reliability of Myers-Briggs type indicators. It’s generally understood that your MBTI type is only somewhat useful when it comes to personality analysis. As with all dating site matching systems, several different tests and questions should be used to get a complete picture of yourself and the people you might be most compatible with. Relying on WeAttract’s tests or eHarmony’s 436 questions is the tip of the iceberg. Better tests are just around the corner.
