That is an interesting article thanks! I think it's right, but also there's an aspect of humility that the author doesn't really touch on, and that's people who are quite disenfranchised. It's not so much "whatever, man" as "I am probably wrong because I am dumb/people like me don't know things like that/can't do that".

I used to see it a fair bit in nontraditional students. So, I'd suggest another fundamental component that has to be nurtured sometimes is sapere aude ("dare to know"). Having the courage to not only accept humility, but to try for more knowledge anyway.
