Well, if that is the case, then it would probably be hard to actually accuse the person of behaving unethically.
I'm extremely pasty white, blond hair, blue eyes, Norwegian last name. But 23 and me said that I have 0.1% North African ancestry, or 1 ancestor from ~1600 AD..so African American it is!
> Would they really? Was Elizabeth Warren punished by Harvard or UPenn for unethical behavior?
Good question.
Just because they can doesn't mean they will.
As I said elsewhere, I think that the most likely filter for race bamboozlers is in the application process when the stated race and the combination of application, references, and alumni interview does not tell a coherent story.
Regarding Warren specifically, I will honestly say that I don't think race mattered very much for her. I know it's a meme in certain circles, but she applied in a very different era, one in which admissions standards were much lower. Being capable and ambitious was probably enough regardless of her race. I could be very wrong about her specific case, but I am certain that the Harvard and Penn of that era was nothing like the Harvard and Penn of today in terms of competitiveness of admissions.
