I don't need to, all I need to examine is whether I suddenly get a huge influx of downvotes after this. This happened before when I off-handedly mentioned Ayn Rand as an example of a crazy person. If it happens again, it's weak evidence in favour. You're right though, the lack of control and analysis makes this mostly just a joke hypothesis.

Edit: Oh there we go, I'm at -12 now. It didn't seem to happen until after I mentioned Ayn Rand though, so maybe it's exclusively mentioning her that somehow causes people to go off their rocker. Or possibly it's entirely unrelated, but still.

Edit 2: And now I went from -12 to +20 within minutes. I guess the other team just arrived? This is actually pretty funny to watch. It's a bit like a football match, only my ego is the ball.

Edit 3: And now I am at -5 again. Looks like some people just downvoted all my posts in this thead again. I wonder if there is any pattern behind these waves of up-and-down voting, or if it's just statistical clustering.
