Structure
When used together with an adjective, 不怎么 becomes similar to 不太, which means that the degree of the adjective is not very high.
Subj. + 不怎么 + Adj. / Psychological Verb
Using this grammar structure is a way to indirectly or mildly state something. Instead of saying "他不聪明" (tā bù cōngming) you can say "他不怎么聪明" (tā bù zěnme cōngming), turning a very direct statement to a milder, more wayward statement.
