I like the sentiment behind this, but (and this is a big but) but it looks like this initiative will fall prey to the vices of STEM, namely a tendency to pursue scientism while being ignorant of non-STEM subjects (I'm looking at you Neil DeGrasse Tyson).
Good scientists are often well learned about the humanities. As a rule (because first-class science is multi-national) they are likely to have the ability to deal with ethnic and cultural diversity. What they might be poor at is relating to the mass low culture, not that relating to mass low culture makes one better.
Is this based on some mass survey of scientists, distinguishing them both by level of urbane sophistication and by how "good" they are to produce a strong correlation? A guy who works his ass off in a labor sixty hours a week to bust out of a a doctoral program in record time has little room to feel pressure to learn French or read Dostoevsky. Moreover, a number of "good scientists" may themselves come from the lower echelons of (even white) society.
