Nonsense. NSF awards are all public. If you could actually give enough examples of these "extremely large" awards to constitute 55% of the NSF budget you would have.
But more importantly, I'm familiar with the linked document, and it's garbage. It was thrown together practically overnight to justify a political decision that had already been made, and in its incompetent haste, flagged proposals that had phrases like "diversity of sources" that had nothing to do with DEI and included them in the totals. Not a credible source.
That's not siphoning anything away from science -- it is science.
Completely aside from the incompetent misidentification of which proposals have anything to do with race, gender, or sexuality (hint: it's a lot less than 25%), the staggeringly stupid premise that all of them are inherently politically-motivated is part of the problem here.
