High-IQ society (5)

I believe the answer is:

mensa

'high-iq society' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for mensa that I've seen before include "IQ-based organisation" , "Stars" , "Organisation for the clever" , "High IQ society" , "High-IQ organisation" .)

I've seen this clue in The Wall Street Journal.
