Totally untrue. Maybe that's your perspective or that of your admissions committee but it in no way applies across the board and the fact that you imply that is a complete disservice to not only this poster but the community as a whole.
In our Adcom, I constantly hear this line of thought:
"why should we take a risk on this kid when we have so many other kids who don't cheat?" This is what the OP is up against.
Now, different Adcom members will view cheating incidents differently. There's cheating like the OP did, which I consider relatively minor, or copy/pasting right from Wiki or other sources without any citations (or, more commonly forgetting a few citations...this is sloppiness, not cheating). I'm more willing to gamble on people like this, especially if they own what they did.
But every now and then I'll see an SDNer say
"I was too busy" or
"I had a deadline". These are excuses, and I have no tolerance for them.
And then there's CHEATING! Some real life examples I have seen from applications, and from SDNers:
having someone take an exam for you,
breaking into a professor's computer to steal tests,
stealing a test off of a desk
overtly obviously looking over someone's shoulder during an exam and copying answers,
using a cell phone during the exam
using crib sheets during an exam
buying essays from a service
fabricating or falsifying data
With the first example, a fellow Adcom member said that they believe in redemption...the rest of us did not though.
My clinical colleagues (both MD and DO) seem to be the harshest on cheating IAs. They take professionalism very seriously, knowing that dishonest doctors start out as dishonest students.
