what do I know

I'm not sure

What do I know is a rhetorical expression acknowledging the limits of one's own knowledge or judgment.

It often follows an opinion the speaker suspects may be wrong or unwelcome: Maybe she's telling the truth—but what do I know?

The phrase can be genuinely humble or pointedly sarcastic, suggesting the speaker's view has been dismissed unfairly.
