Quote From r90:
Are we talking here about the intentional act of falsifying data only? Or also about the unintentional plagiarism? Also and in worst case scenario, do you think that the consequences of such acts of mine (both the intentional and the unintentional one) would go as far as revoking my degrees?
Both. I know some academics in Germany have had their PhDs revoked for plagiarism as you have described but that is because they are high profile. It doesn't matter for you. Of course, there's always the risk that at some point in the future if you became a high profile academic and someone investigated your work the degrees would be revoked, but this is very unlikely.
If it helps, pretty much all the international PhD students I know weren't aware of the plagiarism rules and thought what you were describing was ok. I'm sure their masters theses were plagiarised in this way too. Plus, on this basis, I expect many students at your university plagiarised, what are they going to do, revoke all their degrees too? And I've seen a recent article saying something about undergraduate plagiarism being very common when it comes to data collection, so I really wouldn't worry too much. Just don't repeat the mistake.
