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'm having trouble seeing this distinction. What if I had a moral obligation to do as well as possible on my current project, because people were depending on me, say? My concern would be that, if I read the reports, I would feel a pull to act immorally. I might even rationalize away the immorality under the influence of this pull. In effect, I would act according to different moral values. Would that make the situation more analogous in your view, or would something still be missing?
I'm getting the sense that the problem with my example is that it has nothing to do with political correctness. Is it key for you that WrongBot wants to keep information out of his/her brain because of political correctness specifically?
I called it a "twiddled" version because I was thinking of the uncertainty as a continuous parameter that I could set to a wide spectrum of values. In the actual situation, the dial was pegged at "almost complete certainty". But I can imagine situations where I'm very uncertain. It looks like part of your problem with this is that such a quantitative change amounts to a qualitative change in your view. Is that right?
I take it that your concern would be that losing creationism would change your moral values in a dangerous way. Whether you are being rational then depends on what "put off reading it indefinitely" means. I would say that you are being rational to avoid the book for now only if you are making a good-faith effort to determine rationally the conditions under which it would be safe to read the book, with the intention of reading the book once you've found sufficiently safe conditions.
Part of the problem I'm having with your example is my perception of the magnitude of the gap between what you are talking about and WrongBot's examples. While they share certain similarities it appears roughly equivalent to a discussion about losing your entire life savings which you are comparing to the time you dropped a dime down the back of the sofa.
Sometimes a sufficiently large difference of magnitude can be treated for most purposes as a difference in kind.
