As a teacher (CS and Math) for over a decade, I agree with much of this. I will only add that, as far as grading is concerned, I think the long-term incentive for the teacher is actually to put almost no effort in at all. There is no pay or status increase for teachers who are tough, consistent graders. In fact, some of the most revered teachers I’ve known essentially hand hold their students to a guaranteed A in the class. At first, principled teachers may stick to tough grading, but as the years go by and they watch their friends easily make 3x more in industry, the incentive to just put a check mark on every paper is about the best you can do to close that benefit gap.

When I was an adjunct (EE and Math), it was widely known amongst all of the teachers, that the student evaluation scores were primarily a measure of what grades the students expected. And I had to ask myself: If I were a student again, why would I adopt any other strategy?

I don't remember if it was a formal study but somebody has asked students at the beginning of the course what grade they _think_ they'll get and at the end it fit very well. Basically all students try to make a particular grade with the least effort, since that's what they are incentivized to do.

Indeed, since the evaluations are handed out before the final grades are tabulated, they can only be based on expected grades. But expected grades are still a better performance metric than a coin toss.
