I still say that there is a difference between what you and WrongBot are doing, even if you're successfully shooting down my attempts to articulate it. I might need a few more tries to be able to correctly articulate that intuition.

My worry was that this would revise my values: after gaining that specific knowledge, my brain would excessively value replying to the reports over working on my current project.

These are not the same types of values. You were worried about your values about priorities changing, while under time pressure. WrongBot is worried about his moral values changing about he treats certain groups of people.

But in the "twiddled" version, I don't know when the safe conditions will occur . . .

True, but there wasn't the same magnitude or type of uncertainty, right? You knew that you would probably be able to read your reports after your deadline...? All predictions about the future are uncertain, but not all types of uncertainty are created equal.

I would be interested to hear your opinion of a little thought experiment. What if I was a creationist, and you recommend me a book debunking creationism. I say that I won't read it because it might change my values, at least not only the conditions are safe for me. If I say that I can't read it this week because I have a deadline, but maybe next week, you'll probably give me a pass. But what if I put off reading it indefinitely? Is that rational?

It seems that since we recognize that rationalists are human, we can and should give them a pass on scrutinizing certain thoughts or investigating certain ideas when they are under time pressure or emotional pressure in the short term, like in your example. But how long can one dodge inquiry in a certain area before one's rationalist creds become suspect?
