- Identify knowledge that may be dangerous. Forewarned is forearmed.
- Try to cut dangerous knowledge out of your decision network. Don’t let it influence other beliefs or your actions without your conscious awareness. You can’t succeed completely at this, but it might help.
- Deliberately lower dangerous priors, by acknowledging the possibility that your brain is contaminating your reasoning and then overcompensating, because you know that you’re still too overconfident.

- Just don’t do it. It’s not worth it. And if I found out, I’d have to figure out where you live, track you down, and kill you.

That said, I'm not sure the analogy with PUAs is usably solid even in those terms ... need to come up with one that might be.

So, it had at least 70 years of growth as an often superior alternative to mainstream medicine, which was murdering its patients through ignorance.* As well, Avogadro's number wa... (read more)
