wisdom
Wisdom is primarily used as an uncountable noun when referring to the quality of being wise. For example, you would say "she has great wisdom" rather than "she has many wisdoms." When used to describe a specific piece of advice or a common belief (as in "conventional wisdom"), it can sometimes act as a countable concept, though it usually remains singular in general conversation.

Just leaning into the conventional wisdom here and skipping the prep call.
Jessica
You're totally winging it. We are going to crash and burn.

David uses 'conventional wisdom' (the second definition of the word) to justify his laziness, while Jessica responds with the idiom 'winging it' (doing something without preparation) and 'crash and burn' (to fail spectacularly), highlighting their contrasting professional styles.
