‘Criminal Minds’: How Matthew Gray Gubler’s Superstition Affected Dr. Spencer Reid

Over 15 seasons of Criminal Minds, viewers fell in love with the endearing, intellectual Dr. Spencer Reid. Reid, played by Matthew Gray Gubler, aimed to understand the psyches of criminals (or, soon-to-be criminals) as part of the FBI’s Behavioral Analysis Unit on the fan-favorite CBS drama. 

As with many actors, Gubler came in with a backstory in mind for Reid. It shaped the character over the years and gave Reid some quirks and personality the writers might not have thought of on their own. In some ways, the idiosyncrasies helped Reid to become an extension of Gubler. Among them was an odd habit about his socks.
