The problem is that genomics (and anything to do with heredity before it) has been and still is abused in the opposite way: people pretending it to be an inevitable predictor like the law of gravity is, while claiming to not have any social agenda until they have had a glass of wine or two and you start hearing absolutely disturbing things.
I've worked for molecular neurobiologists working on brains - the vast majority of them are fine. They research schizophrenia and such that do have genes associated with them, but also get that a lot of the genetics are about incrasing risk factors, not determinism. But once you hit the sub-group that researches the heritability of IQ... well, let's just say that there is a very suspicious aspect to the self-selection bias in the people who decide to research that topic.
