Wouldn't it be nice to get a glimpse of tomorrow based on something as simple as where the sun, planets, and moon were located when you were born?
That's what astrology claims to do, what 50% the world at least partly believes, and what as much as 2% of the planet strongly buys into.
Yet thorough scientific investigations of astrology have failed, again and again, to back up any predictions from an astrological sign or horoscope.
A 1985 study in Nature is especially notable. In that experiment, scientists used a non-biased, double-blind protocol and worked in conjunction with some of the top astrologers in the US to test the predictive power of astrological signs.
The results? The astrological predictions were no better than chance.
