To add to this, there's also the element of betting.

Humans, even rationalists, have to make decisions without the time to obtain perfect knowledge. It's only prudent to place bets if you think the upside might be big and the downside small. In other words, there were probably rationalists in the OP's sample that donated/took money from SBF while thinking this is all likely going to blow up in their face. This isn't the case of conflicting beliefs--it's playing the odds.

Plus, the characterization of "rationalists" seems to me a faulty generalization. There are probably very few people who make their life revolve around rationalism. But rationalism isn't some monastic order that stamps out mentat-like Rationalists, so in the real world, "rationalist" describes everyone from hyperlogical baysian wizards to folks who like a good argument and enjoy eating popcorn while watching the Culture War eat itself.

Humans, even rationalists, have to make decisions without the time to obtain perfect knowledge.

Yes, sometimes, but a lot of times they don't have to make a decision, and they do anyway. For example if I enter a meeting I will want to sit down, I don't know if the chair isn't broken, but I sit down anyway. Is not checking the chair a mistake? No, I can make a decision without perfect knowledge. But what about a raffle? I also don't know that I'm going to lose, so it might make sense to buy a ticket, but I don't have to. You'll say that I made a decision anyway, but not necessarily, a lot of times the result is "I don't know", and that's not really a decision.

That depends on the odds. A small upside and big downside might make sense if the odds of losing are sufficiently small.

But those are two different things. Taking money from a person is one decision, trusting that person is a completely different one. You can take money from a person without trusting them.

The difference between skeptics and normal people is not readily apparent. We both sit on a chair without checking if it's broken, but I as a rational skeptic do not assume it is unbroken. The end result looks the same, but the mental model is different: I do not have a belief.

but I as a rational skeptic do not assume it is unbroken.

And yet you assume you have access to other people's mental models.

No, I ask them what they believe, and they tell me.
