Usage Note: The usual meaning of simplistic is "characterized by oversimplification." It is occasionally used to mean "simple," with no negative overtones, but this usage, as in The song is short and sweet, with admirably simplistic lyrics that carry such depth in so few words, was rejected by 84 percent of the Usage Panel in 2011.
