I honestly think that Trump is the application of postmodern concepts to politics on an unrelated precedented level and many people on the left who supported these ideas find them horrifying when they are used to bolster positions that are not theirs.
You want science better represented in society and politics? Get more scientists involved in society and politics. http://www.314action.org/home
As far as how I 'want' it to be influenced, I think civil society should be entitled to discuss the implications and validity of research that is done (in this case, racial or ethnic factors in 'standardised', culturally based tests of 'intelligence'), as well as set large scale priorities as to where effort should best be focused, like in your examples.
I strongly disagree with the rationalist fallacy that science must progress unfettered by social or political 'ideology'. The very notion that science is ideologically blanched, that it exists in some asocial vacuum, is naive at best, disingenuous at worst, and misguided always.
To paraphrase John Wheeler on spacetime: Society tells science how to move; science tells society how to curve.
