A few examples (in approximately increasing order of controversy):
If you proceed anyway...
- 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.
- Spend a disproportionate amount of time seeking contradictory evidence. If believing something could have a great cost to your values, make a commensurately great effort to be right.
- 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.
This seems to be bordering on Dark Side epistemology - and doesn't seem very well aligned with the name of this site.
Another argument against digging in some of the red flag issues is that you might aquire unpopular opinions, and if you're bad at hiding those, you might suffer negative social consequences.
Dark Side epistemology is about protecting false beliefs, if I understand the article correctly. I'm talking about protecting your values.
