I teach a week of professional ethics to freshmen as part of an honors college course. It's interesting to
hear them debate how to deal with research ethics and plagiarism. I use news stories as a starting point for topics. There's no shortage of misbehaving scientists. Case in point: UNLV English professor Mustapha Marrouchi has a long history of plagiarism, as chronicled in the, uh, Chronicle of Higher Education.
Here's my problem: I want to scare students straight about this. They shouldn't plagiarize just because they'll get an F on an essay. Plagiarizing can ruin a career. But, it turns out, Marrouchi has a very respectable career and his plagiarizing ways seem to be well-known (according to CHE). This is the WORST example I can give the students. "Don't plagiarize because, after gaining respect of your peers and notoriety as an expert in your field, at the end of your career you'll be asked to quietly retire after people find out you've cheated for many years." Not exactly the message I want to send.
The Cabinet of Plagiarism has an even more depressing take on this affair.
