The term "idiot" is used as hyperbole, to reassure readers that the guides will be basic and comprehensible, even if the topics seem intimidating.

Alpha Books, publisher of the Complete Idiot's Guides, is a member of Penguin Group.
The editorial offices for the two competing series are both located partially in Indianapolis.
