I would defer to Gay and her peers in her field, specifically. This whole issue is a referendum on the dangers of surrendering expertise to the internet and Google rather than people who have spent years working in this speciality.
Resignation is probably an inevitable outcome, because regardless of what the findings of the scholarly investigation by peers would be, the allegation would be used as a cudgel throughout her tenure. And because women and people of color have to be twice as good and perfect, it would be used to prove that she is not qualified for the job. It’s a lose-lose proposition and personally, I think she made the right call if she is centering her well being. College presidencies are awful jobs, and probably there is no more awful job than the one at Harvard.
Bill Ackman is a terrible human being. He had no regard for Claudine Gay’s family or well being during his screeds on plagiarism which offered no nuance, and importantly, seemed to take delight in the accusations agains Gay - and immediately connected it to a lower standard because of her race and gender. He doesn’t appear to have the same energy for his wife’s accusations. In the case of both scholars, their work should be investigated by a committee of peers. And there are gradations of academic dishonesty from incorrect citations to research fakery. Every scholar knows that, but this isn’t Bill Ackman’s field, and he decided with Chris Rufo to lead the battle against plagiarism. Perhaps he should have spoken with someone with some expertise in the area before doing so - like his wife?
I mentioned earlier that I sat on a Committee of Rights and Responsibilities at Harvard as a grad student. We rarely expelled or revoked degrees, as Nicest_of_the_Damned noted. The point of a judicial process is educate the person found responsible, and do what we can to lessen the possibility of it happening again. People are obsessing with a narrow definition of plagiarism being “stealing ideas and passing them off as your own.” In both Gay and Oxman’s cases, from what I’ve seen, that is not what is occurring.
People make mistakes. My first book has typos in it - the book was typeset incorrectly. One of my earliest articles was published with odd characters in it (the journal did reprint it). Even accomplished senior scholars make mistakes. Miscalculations, misattributions, and so forth. It’s idiocy to act as if this doesn’t happen. In fact, if I was in a disciplinary hearing, it would helpful to say that citation errors are common - it even happens with senior scholars. (A significant part of our work was helping students work through shame - these were high achieving people who would never categorize themselves as “cheaters.”)
It’s emotionally devastating to have your work dismissed because of an error, or a number of errors. And I would make a clear delineation between someone who fakes data or steals ideas for others, and someone who did not accurately cite sources (or did so awkwardly).
I have run my papers through iThenticate and the things that are detected do not always legitimately rise to plagiarism. Indeed, there are papers published after mine that have similar language, and the one I did investigate I would not consider plagiarism (we were both describing the tenets of Critical Race Theory in educational settings). The ability of AI and large language models means that we can produce reports completely free of nuance.
Being president of a university does have an ethical dimension - I don’t think presidents should be people who have been convicted of impersonating a police officer, for instance. But a president who is a human being and/or admits to mistakes can be a powerful role model. Santa Ono, the president of the University of Michigan, has spoken openly about his bipolar disorder and suicide ideation. (Please note I do not consider bipolar a “mistake” - it’s part of who he is.)
There’s nothing problematic about an institution sanctioning and dismissing a student who steals answers from a test key, and having a more educational sanction for a student who has problematic citations - you can point to the fact that even the president of the institution has been sanctioned for these errors.
The other thing I see a lot of with the Oxman accusations is that it’s different because Oxman is a faculty member and Gay is a president. I am both a senior administrator and a professor, and academia is famously a space where peer relationships are valued. It is not similar to a corporate setting where a president can fire a subordinate; in fact, I think most faculty members would laugh at the idea that the president is their “boss.” (Technically, they are supervised by department chairs, deans, and a provost.) Academic dishonesty is a problem for both of them, and the need for sober and careful investigation of their work is equally needed.
