One of the faculty members at my school asks everyone he interviews if they've cheated in school. If they say no they'd better be prepared to prove it somehow, cause he's convinced (as am I) that everyone does it a little at some point.
His take is that if you can't admit to something as innocuous as asking a friend for the answer to a homework question (when you were supposed to work on your own) then how can you be trusted to be honest when you accidentally hurt someone as a physician? And if you cant even realize when you are cheating then that's a problem too. Let's face it, we're all goig to make mistakes as doctors, can we own up to them and admit fault or will we try to deny wrongdoing and push the blame on someone else? Or worse, will we fail to see that we did anything wrong in the first place?
This faculty member (a young, but retired general surgeon) tells us he was never sued. He feels that the main reason is the when he made mistakes, he owned them, explained to the patient how they happened, and apologized.
That's a long winded way of outlining the problem with cheating, especially cheating and denying. It undermines your integrity, something of critical importance for a physician. No school wants someone like that on their alumni roster.
