- (1)You're working on a paper with multiple citations throughout, and accidentally delete a footnote or move it to a different sentence while rearranging sentences. Boom, you've plagiarized because you didn't cite the statistic or idea you quoted in that sentence. And yes, I have seen people at my school who would NEVER cheat get in trouble for this.
- (2)You have done lots of reading on a particular topic, and while writing your own sentence attempting to paraphrase without referring back to the paper, you accidentally use the same phrasing as the original and don't put it in quotation marks. That's plagiarism.
Heck, when I was in 7th grade I once got accused of plagiarism on some dumb paper for my art class because the teacher said my writing was "above grade level"...I was reading at a college level at the time (and I didn't plagiarize). What if that had happened in 9th grade and my principal had been less reasonable and believed the art teacher instead of me, and something went on my transcript? Would I have gotten into a four year college?
ETA: Now, of course there are people who purposefully plagiarize like what
LizzyM describes below - those people should be punished appropriately. But I don't mind cutting a little slack to somebody who unintentionally forgot to put in a single parenthetical citation.
And you still didn't answer my question...do you think cheating/plagiarism is unethical or not? You said cheating is no biggie because everybody does it in one post and criticized someone for having leniency about unintentional plagiarism in the next. You don't sense the cognitive dissonance there?
