pick someone's brain

Extract someone's knowledge

To pick someone's brain is to question them thoroughly to extract useful information or expertise: Can I pick your brain about the housing market?

The phrase treats another person's knowledge as a resource to be mined.

It's informal and usually implies the questioner wants practical insights rather than casual conversation.
