Idiot Savant: An individual who exclusively focuses on the mastery of one aspect of performance (e.g. doing math, playing the piano), to the exclusion of all other skills, both technical and interpersonal. Known in less severe cases as nerd savants. Idiot Savants are to be distinguished from those folks who focus on all aspects of performance and are masters of none, but think they are savants one way or another. They are known as 'that bunch of idiots' or more formally as religious fundamentalists or Republicans.
