Most colleges have done the opposite in recent years. They provide echo-chambers for emotionally-fueled pseudoscience.
I've seen this while spending time at Boston University, Harvard, Brown, and Columbia. It's frightening how little people are able to think or question anything once they've gone through the college system. They become frightened by and angry at truths that don't align with the narrative they've been taught.
I've spoken to dozens of people who've gone through the wringer and come out the other side realizing how detrimental college was to themselves and their peers intellectually.
