The bystander effect question that you mention was worded pretty poorly. The first sentence implied that the total probability is lower when there's more bystanders (which is definitely false in sufficiently large numbers), then in the second sentence their wording switches to marginal probability, which is correct. I of course knew what they meant, and answered correctly. But there were a handful of somewhat ambiguous questions like that. A handful I legitimately didn't know, such as whether people remember the last argument the best. 34/40.
