The dissing of PhDs is unwarranted. Gross over-generalization. People being skeptical of ideas in a peer-review sort of way can be both good and bad. For example, the assumptions and claims of this article can do with a substantial amount of skepticism. Perhaps someone should express skepticism and view this article with the peer-review critical eye that he mentions.
I am reminded of climate-change skeptic articles that say “hey these scientists know nothing. See today it’s 10 below zero. Common sense! No global warming.”
