>>>Certainly not all - and probably not most - college students cheated and plagiarized.
It has neither data nor studies. It is Sue Carter Simmons' professional opinion.
That said, I agree with you that modern kids don't necessarily cheat more than non-modern kids do. I agree that parts of theologic's comment were directed at "modern kids" and the teachers of these modern kids. I can see how a reasonable person (you, stdbrouw) could infer that theologic was saying that modern kids have different cheating habits than non-modern kids. I submit that there is another reasonable person (myself) that does not infer that theologic was saying that modern kids have different cheating habits than non-modern kids. Let me explain:
>>> The best way to slow cheating is to not give an opportunity to cheat in the first place
This is the last line of theologic's comment. The proposed "best way to slow cheating" works equally well for modern and non-modern kids, it does not target either group.
The other references to modern kids inherently do not explicitly say anything about non-modern kids. There is no comparison or contrast, which leaves room for you and I to make our opposing inferences.
To be fair, if theologic had said something explicit about non-modern kids, I would tend to agree with your inference.
