Testing Astrology is Futile
Skeptico has an exhaustive list of formal tests that astrology has failed. 37 in total. If any other theory had failed that many tests, you would think that the proponents would have moved on by now to better things. Not astrologers. Indeed, there’s something rubber-duck-like about their resistance to any evidence against their claims. No matter how hard you push them down, they pop right back up, bobbing happily in their stagnant water. Testing astrology is futile, not because it cannot be tested, but because the people who most need to understand the results refuse to even look at them.
Even when astrologers are consulted on the tests, asked to design the tests, and state with great confidence before the tests that they will definitely obtain better than random results, the tests still return results consistent with guessing. This is the point where they seem to completely forget that they stated the test was valid, and begin finding all manner of excuses for why the test was invalid and astrology still works.
They call astrology the first science, then claim that it can’t be explained by science. They claim that the correlations between man and the heavens are so strong that early astrologers could create rules for those correlations by means of logical deduction, but then claim that logical deduction is not an appropriate method by which to test those rules. They claim that the rules of correlations are so accurate as to allow prediction of future events, then claim that those predictions may or may not come true. They tell skeptics of astrology to keep an open mind to the idea that it works, but themselves refuse to keep an open mind to the idea that it doesn’t. They claim that they are convinced that astrology works because they have seen evidence of it working, but then claim that a search for evidence of it working is not an appropriate test that it works!
How is it possible for a healthy human mind to contain this kind of cognitive dissonance without exploding?
