Densa

Densa has been used as the name of a number of fictional organizations parodying Mensa International, an organization for highly intelligent people. Densa is ostensibly an organization for people insufficiently intelligent to be members of Mensa. The name Densa has been said to be an acronym for "Diversely Educated Not Seriously Affected." The name Densa is a portmanteau of and Mensa.

History

The concept of an organization for the mentally dense originated in Boston & Outskirts Mensa Bulletin , August 1974, in "A-Bomb-inable Puzzle II" by John D. Coons. The puzzle involved "The Boston chapter of Densa, the low IQ society". Subsequent issues had additional puzzles with gags about the group and were widely reprinted by the bulletins of other Mensa groups before the concept of a low IQ group gained wider circulation in the 1970s, with other people creating quizzes, etc.
A humor book called The Densa Quiz: The Official & Complete Dq Test of the International Densa Society was written in 1983 by Stephen Price and J. Webster Shields.
