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.
Becoming more convinced of your own position when presented with counterarguments is a well known cognitive bias.
Knowing about biases may have hurt you. The counterarguments are not what convinced me; it's that the counterarguments describe my post as bad because it belongs to the class of things that it is warning against.
There are other counterarguments in the comments here that have made me less convinced of my position; this is not a belief of which I am substantially certain.
