A word for a worldly wise person who pretends to be naïve?

What is a word for someone who is experienced and wise, but who deliberately acts naïve?

I don’t intend it for sarcastic use; I’m trying to describe someone succeeding in making people think that that person truly is naïve.

Is there a word for this?


Solution 1:

I’d probably go for disingenuous: “Assuming a pose of naïveté to make a point or for deception.”

Solution 2:

Feigned ignorance is an expression used when someone pretends to be uninformed or unknowledgeable about something.

Solution 3:

You could call them faux naïf.

Solution 4:

I would go with "Lt. Columbo".
