Mad scientist Mad scientist (also mad doctor or mad professor) is a caricature of a scientist who is described as "mad" or "insane" owing to a combination of unusual or unsettling personality traits and the unabashedly ambitious, taboo and/or hubristic nature of their experiments. As a motif in fiction, the mad scientist may be villainous (evil genius) or antagonistic, benign or neutral; may be insane, eccentric, or clumsy; and often works with fictional technology or fails to recognize or value common human objections to attempting to play God. Some may have benevolent or good-spirited intentions, even if their actions are dangerous or questionable, which can make them accidental villains.
