I would not put all HNers in one basket, but I have noticed on topics about studies, and on several societal topics that there is a tendency in our community to put hard sciences to the pinnacle, and to overlook the benefits of humanities. The extreme manifestation of this phenomenon is, to me, the SV creed of engineers disrupting the society for the best.
I was lucky enough to have someone show me this, and now I try to spend a fair amount of my time educating myself not only in my field but also in philosophy, sociology, etc. I am happy to discover these now, rather than after a life of making things I would regret.
There are many good principles that come from social sciences and such. The problems are:
1. It's difficult to make a career in it unless you apply it in a non-traditional way. Many kids are often misled by that.
2. There is a lack of rigor, politics-under-the-color-of-science and experimental reproducibility problems in the humanities and social sciences, and it's the negative downside you have to look out for.
3. Postmodernism tends to be toxic and makes you ineffective. People repulsed by it go into more concrete things like STEM by instinct when they are young.
