I do suppose that fields can make a fundamental difference.
I'm in Chemistry, and our exams tend to be a mix of graded work and open response problems. In many cases, an open response problem is not so much an essay, but is rather either a math problem or requires the student to draw a diagram or figure to answer it(often times accompanied by a short explanation about why a particular answer is correct).
When grading, we have to be very diligent about indicating on the exam paper when something is missing that should have been there-again it's non unheard of for a student to go back and add to their answer after receiving their exam paper back, then claiming that part of the answer was missed in grading.
The vast majority of students I deal with are superb, but the ones who put more effort into cheating than actually learning the material make all of this necessary.
And, again, since I'm often dealing with pre-health students, the "cheaters" are often the ones who need to be "weeded out" before they enter a professional career where they can-quite literally-kill someone.
