I can’t imagine how, unless you only had 20 of them or something?
Back when I was a TA, I had an average of 120 students per semester and we didn’t necessarily grade our own students’ work (it was usually divided by topic).
So if I’m grading 120 assignments - or worse, 480 pieces of exam assessment- and only 25% of them are from students I regularly interact with, I don’t think my subconscious has any idea 99% of the time.
Even with smaller classes… you’re just seeing too many people with similar thoughts and styles over the course of a year for any of it to imprint on your mind that deeply. Occasionally it’s going to be obvious, but I still think removing a level of bias through anonymizing is best practice.
