>For BS answers I'll admit I got less generous as the hours went on.

What do you think is the cause of this? Do you become more cynical (and less generous) because you’ve seen so many BS answers previously? Is it just that getting fatigued makes you less generous?

When I was a TA in grad school, I noticed the same. Early on I thought some BS answers were at least kind of funny, and I gave them the benefit of the doubt, maybe giving more attention to the parts that were correct. After I saw similar answers later on, the novelty wore off and I was probably less amused, so the inclination to be lenient disappeared. Sometimes I went back to previous decisions if I remembered them, to be fair, but I don't think I always remembered since the volume could be high (grading 80 exams in a row is TEDIOUS).
