Agreed that rationality is mentally tiring...I went back and read your comment, too. However:
A more realistic expectation is that people should identify the things they need to think extra hard about, and correctly use rational thinking skills at those times.
To me, rationality is mostly the ability to notice that “whew, this is a problem that wasn’t in the problem-set of the ancestral environment, therefore my intuitions probably won’t be useful and I need to think”. The only way a rationalist would have to be analytical all the time is if they were very BAD at doing this, and had to assume that every situation and problem required intense thought. Most situations don’t. In order to be an efficient rationalist, you have to be able to notice which situations do.
Any question on a written test isn’t a great measure of real-life rationality performance, but there are plenty of situations in everyday life when people have to make decisions based on some unknown quantities, and would benefit from being able to calibrate exactly how much they do know. Some people might answer better on the written test than if faced with a similar problem in real life, but I think it’s unlikely that anyone would do worse on the test than in real life.
