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.
I am presently amused by imagining forum members declaring themselves "anti-truth".
Though I guess there is a spectrum from sticking to discovering and exposing widely applicable truths no matter what, some kind of Straussian stance where only the enlightened elites can be allowed access to dangerous truths and the general populace is to be fed noble lies, and then on to even less coherent spheres of willful obscurantism and outright anti-intellectualism, where it seems that nobody is encouraged to pursue some topics.
For some reason though, people who either explicitly believe that noble lies are necessary or have internalized a culture where they are built-in never seem to claim to be anti-truth.
