Scrutable

Does astrology work? We tested the ability of 152 astrologers to see if they could demonstrate genuine astrological skill.

Here is how the study was designed and what we found...

For people not on twitter, they asked astrologers to read profiles of people and then pick their birth chart (time, date. position of planets etc) from a choice of 5 - one based on the actual birth date, 4 using other dates.
Not surprisingly, they didn't do significantly better than random guessing.
Further detail in the thread.

Reminds me of a blowhard "true" astrologer over on ISF/JREF who insisted that, given a person's time and place of birth, a true astrologer could accurately predict when the person would die. Of course it would be unethical to tell people when they would die so, alas, no true astrologer would be so low as to be tempted by the cash of the JREF million dollar challenge and prove their paranormal ability.

I suggested they could easily be tested with a list of the birth details of people who had already died and it went a bit quiet.
