Hey man did you see that improv show last night?

Yeah, the second group was off the chain, but the opening group was straight up improverished!

imparverished 

Of severely-limited means due to excessive adherence to Hebrew practices.

Tevye and his fellow "Yiddishmen" were so "imparverished" largely due to their obsessively following da foolish and woefully-outdated "Old Testament" ways ("Tradition!") of their equally-closed-minded-and-clueless forebears.

Intellectually Impoverished 

Inability to make effective life (enriching and/or saving) decisions, absent of preexisting mental health illnesses or substance abuse/addictions, based on a lack of knowledge or exposure to positive, grow producing, cultures and intellectual developmental externalities beyond an individual's parochial socio-economic, academic and cultural experiments.

Her intellectually impoverished mindset limits her ability to interact with people who are not from the same neighborhood.
