Another way to say that is that teachers are privileging their own subjectivity. When that happens, some people, caught in the conflict of trying to satisfy competing interests, resort to cheating as a means of survival. Many of you have written to say just that. That doesn't make cheating moral. I think that might be easier to do, if we think of cheating as a magical potion designed to reduce the stress and let us cope with conflicting demands.
Some magic potions are relatively harmless.
Others ruin lives. We need to deal with this as an issue of public discourse in the academy. I thought this exercise was a fun way for students to view cheating. This would have been the ultimate answer that I would have chosen. Susan got this through to me.
