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.
Errr, how? I am familiar with the practice of precommitment, but most of the ways of creating one for oneself seem to rely on consequences not preferred by one's values. If one's values have changed, then, such a precommitment isn't very helpful.
In the context of the thread we're not talking about all your values changing, just some subset. Base the precommitment round a value you do not expect to change. Money is a reliable fallback due to it's fungibility.
