&gt; BTW, is astrology actually falsifiable? I&#x27;m under impression that astrologists deliberately strive for unfalsifiability exactly to avoid falsification which could cast doubt on their wisdom.<p>It is. Just do the following experiment:<p>Find, say, ten persons and an (or many) astrologists and let them create a horoscope (say, either a prognosis for the future or description of character traits) for these 10 persons, where only the exact time and location of birth is given to the astrologists.<p>After that give all ten horoscopes to all ten persons and let them rank. Now just formulate some sensible statistical model and voila - falsified.
