> Isn't that the precise question that science is trying to answer, but which is being disputed by people who do not like the answers?

Science does investigate all sorts of questions and there isn’t exactly a movement to shutdown neuroscience and psychology research. What there is a reaction to are people claiming to know the answer to these big field-defining questions, which conveniently says that their politics are the only right position, and otherwise claiming the mantle of science while acting contrary to how actual science is supposed to work. Sometimes that includes criticism of scientific figures but that’s when they aren’t doing good science: nobody would question that James Watson is a real scientist but the criticism he gets today isn’t for asking unpopular questions but for falling so short of the standard. Had he wanted to do real research into intelligence and genetics he’d have had no shortage of resources and collaborators but he wouldn’t have the big dramatic claims, just more slow progress chipping away at one of the hardest problems in the world.
