What if OP were referring a similar story with similar thin evidence, but the misconduct was an administrator unfairly denying tenure to faculty while only granting it to friends? What if the misconduct was sexual assault of students, racism, or a subversive effort to close a department and layoff tenured faculty? Would we still be so uniform and vocal in dismissing the evidence outright?
I don't think the scenarios of misconduct call for grossly different reactions. I think in all these scenarios if we are only talking about bar chat (i.e. random gossip), then that's all it is, gossiping.
Would we still be so uniform and vocal in dismissing the evidence outright?
What evidence? (And Untenured, I know you've already accepted this, but I think it bears repeating) The Penn State analogy is a poor one, but illustrative nonetheless. At Penn State, there was an eyewitness account. That is not hearsay.
"I know someone who knows someone who heard someone say she heard the spouse say...." Hearsay
ad infinitum nauseum.
I would hope that we (collectively) would have the same response to any other report of unacceptable behavior - "Really? How do you know that? What's the evidence?"
I agree completely with octoprof and fishprof. If the "evidence" suggesting that an instructor had engaged in sexual misconduct or any of the other activities you named were as flimsy as it is here--so flimsy that one cannot in good conscience even call it evidence--then my reaction would be exactly the same as it is in the OP's described situation. As fishprof says, we are obligated to ask, "How do you know that? What is the actual evidence (versus hearsay, which is
not evidence)?" And if there is no actual evidence, it's time to shut down the rumor mill. I have seen way too many cases where there appeared to be "smoke" when in fact there was no fire at all--and people suffered from the gossip and false accusations. To engage in these activities or encourage them is unconscionable. (Again, theodosia, I'm not talking about you here, but about the people you called the "tongue waggers.")
If there is evidence of wrongdoing, then it should be brought to the attention of the proper folks and in the proper venue (the P&T committee in this case). A whispered smear campaign is never the appropriate way to handle alleged faculty misconduct. And, if there's no actual evidence, then the rumors should be shut down and otherwise ignored.
