The problem people have with Epstein's "support for science" is that he spent his life collecting influential people, and, in at least once notorious instance but likely many others, deploying the influence of those people to his ends, which included the trafficking of minors for rape. One reasonably asks, "was Epstein actually trying to fund science at Harvard? Or was brokering donations for programs he could brag about having a hand in getting off the ground just an easy way to create social bonds with the world's most influential people?" One then looks at what Pinker did for Epstein in 2007 and, probably, quickly finds the answer to that question.
This was also the problem with the MIT Media Lab's policy of denying named donations for Epstein while allowing him to broker donations behind the scenes. They were getting money from powerful people, because of Epstein's work. But MIT and the Media Lab's management missed what Epstein was getting out of the deal.
