Recently on a John Oliver segment, Oliver was speculating on how Trump University received 98% excellent approval ratings from current students. Turns out that the students were asked to give feedback while still enrolled in the course, meaning that giving a bad review could negatively influence their grade or relationship with the teachers, and thus the students were motivated to give more positive answers than they otherwise might have.

I wonder if founders giving answers here had names attached to their answers or if they were anonymous at submission-time.
