My fifth huge mistake was that I—as I saw it—tried to speak plainly about the stupidity of what appeared to me to be stupid ideas. I did try to avoid the fallacy known as Bulverism, which is where you open your discussion by talking about how stupid people are for believing something; I would always discuss the issue first, and only afterwards say, “And so this is stupid.” But in 2009 it was an open question in my mind whether it might be important to have some people around who expressed contempt for homeopathy. I thought, and still do think, that there is an unfortunate problem wherein treating ideas courteously is processed by many people on some level as “Nothing bad will happen to me if I say I believe this; I won’t lose status if I say I believe in homeopathy,” and that derisive laughter by comedians can help people wake up from the dream.
Today I would write more courteously, I think. The discourtesy did serve a function, and I think there were people who were helped by reading it; but I now take more seriously the risk of building communities where the normal and expected reaction to low-status outsider views is open mockery and contempt.
Note that Eliezer has regrets about that:
