But it is like "debunking" astrology. If you think you did, you didn't understand astrology: the "signs" are just to randomize so not everybody gets the same advice on the same day. Its purpose is to keep people out of ruts, for which it works.
This is similar to hunter-gatherers relying on omens to direct where to hunt: it keeps them from exhausting any single place.
It’s purpose is alliviate people of their disposable income for which is also works. Same for personality tests. There are people charging huge sums for going to companies and telling them half their people have purple personalities and the other half mantenga and that’s the core reason why their bus ones hasn’t yet reached the incredible synergy that will make them the next Google or Apple!
I know several people who are very dependent on these personality definitions as a framework for their self-identity, and I would never suggest to them that they were wrong to do so. It makes them happy.
Since the positions of planets can, physically, have no effect, and nobody could ever observe or deduce any such effects, we are obliged to cast about for other design motivations.
