Created by Arika Mittman, The Irrational is based on a book written by Dan Ariely called Predictably Irrational: The Hidden Forces That Shape Our Decisions

The show focuses on a behavioral psychology professor named Alec Mercer as he gets recruited by the government and law enforcement due to his unique ability to profile and analyze people.

In 2022, Mercer was the victim of a church bombing, and the man who did it was Wes Banning (played by Ben Cotton). 

Despite being taken into prison, Banning got a lesser sentence since Mercer couldn't remember details about the scene of the crime. 

However, at the end of Episode 1 during Banning's parole hearing, he mentions that he'd do it all over again if given the chance, leading to the court denying his release. Mercer and Marisa realized that he said that because he saw someone across the room that terrified him. 

Banning is known for his roles in The Chronicles of Riddick, Stargate: Atlantis, and Stan Helsing.
