Astrology benefits greatly from the pigeonhole fallacy. With as few as twelve pigeonholes in most astrological predictions, of course there are going to be enough people overfitted to the model that any prediction "succeeds" for enough people that you can claim all the failures were within the bounds of statistical error. It's related to why MBTI lasted so long as "science" because it proved many concrete predictions through overfitting and hand-waving away errors as statistical anomalies rather than the pigeonhole principle at work. There are still plenty of people that think it valid. Perhaps ironically, MBTI even seems to making a comeback among many of the same people that are flocking to Astrology. If you're going to live by one pigeonhole fallacy you might as well live by more than one, I suppose.
