TA here. How do you stop yourself from subconsciously giving higher marks to students you know will complain about low marks? I'm really busy with everything else and I don't have time for dealing with accusations of misconduct or incompetence from these entitled brats. Problem is, if I fail them, they have nothing to lose from complaining to the professor or department chair about me and I actually have to take time out of my schedule to defend myself.
I want to be honest but it's so tempting to just slip a few extra marks here and there to shut them up.
