Criminology

Barry Allen is a forensic scientist.

Sometimes compared with "psychology", Criminology is a term used to describe the ability of some characters to use their knowledge of criminals or of how criminals function in order to apply their specific abilities to that situation. For instance, Batman understands that criminals are a cowardly and superstitious lot and therefore created a fearsome guise to strike fear in their hearts. Barry Allen is a forensic scientist and uses his "daytime" persona to manage, control and prevent criminal behavior by helping the Central City police solve crimes without being the Flash.
