A month before the paper was assigned a student was talking with their professor and mentioned that the punk band "The Exemplars" was their favorite band and that they would do anything to see them live but that they almost never perform. The day after the paper was due the student comes in and says "I'm sorry I didn't get the paper in on time, professor, but you won't believe what happened. The Exemplars, that band I told you about held a one-time-only surprise concert downtown yesterday and I just couldn't pass up the opportunity to attend. It is true that my excuse isn't traditionally considered a good one like that of the grieving student, but months ago I signaled to you quite clearly that an Exemplars concert would be the kind of thing that would lead me to turn a paper in late. You excused the grieving student because it is assumed in our culture that a death of a family member will give someone reason not to write a paper. But though we don't assume most people will not write a paper because of a concert you could have predicted an Exemplars concert would cause me not to write the paper. This excuse won't be used often by other students since to be successful one has to indicate a stance that would cause them to not write the paper under certain circumstances and then hope those circumstances arise."
But doesn't this make precommitting have a positive expected utility to students, so students would precommit to whatever they thought was most likely to happen and the teacher would still expect more late papers from having this policy.
Well they can't pick circumstances that are actually likely to come about. If such circumstances can be foreseen the professor will have expected the student to finish the paper earlier just in case.The more likely the event the the more likely the professor is to make that determination and not accept the excuse. Presumably there is some ideal rate of unlikelihood that satisfies the professor's utility function.
