I'm a little stuck... Click here to teach me more about this clue!

'strongly inclined to be brainy?' is the definition.
I know nothing about this answer so I can't judge whether this works.

'be' is the wordplay.

'be' could be 'go' (going is a kind of being) and 'go' is located in the answer.
This explanation may well be incorrect...
