> Among those who had ever heard the term, 36% said affirmative action is a good thing, 29% said it is a bad thing and a third weren’t sure.
It was a preceding Gallup poll that found the result you're thinking of:
> By comparison, Gallup has asked U.S. adults whether they “generally favor or oppose affirmative action programs for racial minorities.” In 2021, the last time Gallup asked this question, a 62% majority of Americans favored such programs.
The disconnect between this sort of response with the one you cited at the end of your comment just serves to underline my point about the public's lack of clear understanding of what "affirmative action" means (and they cannot be entirely blamed for this, since in the culture, it has come to mean different things).
Institutions like Harvard will (for the foreseeable future) always have vastly more fully qualified applications than they can accept. The concept of affirmative action was originally intended by its proponents to be used only when tie-breaking between equally qualified candidates. Harvard and the other Ivies have this situation in extremis. The idea was that when faced with the question "well, we have 26 people all fully qualified, how are to pick between them?" that using race was a legitimate choice as long as the racial demographics of the institution did not match those of the overall population. They have (for a while) used gender in a similar way, and arguably could use favorite ice cream flavor if they chose, because the candidates are all qualified to be selected.
There was never a suggestion that "affirmative action" meant selecting less qualified candidates because of their racial status. However, the conservative right has claimed that this is what affirmative action really means in the world, and this idea has been broadly picked up by the media and public at large. Whether there is actually any evidence that this has happened on a significant scale is not something I've seen adequately addressed. From what I have read, including the Harvard case, I'd say it was much more an unfounded grievance on the part of people who felt they had a right to be admitted or hired than what actually happens. I could be wrong.
