Psychologist Explains Why Comedians Like James Acaster May Have an Edge on 'Celebrity Traitors'

Comedians may possess an inherent advantage in reality television competitions like 'Celebrity Traitors' due to a psychological phenomenon known as the 'halo effect,' according to a psychologist.

Paddy Ross, an associate professor of psychology at Durham University, suggests that viewers and fellow contestants alike are predisposed to trust individuals perceived as humorous, a bias that can influence judgments of trustworthiness and deceit.

In celebrity versions of shows like 'The Traitors,' where participants often have pre-existing public personas or professional connections, these cognitive shortcuts become particularly influential. Unlike standard formats where contestants begin as strangers, the celebrity cast may already harbor opinions about one another, creating fertile ground for biases to take hold.

Dr. Ross explained on The Conversation that the halo effect leads people to assume that positive traits, such as humor, correlate with other unrelated positive qualities. "The comedians in the group have an advantage here," he noted.

This theory was illustrated in a previous celebrity series, where comedian Alan Carr, despite being a traitor, was difficult for fellow contestants to suspect. His ability to make others laugh led to assumptions of trustworthiness, a phenomenon Dr. Ross described as "false assumptions about his trustworthiness through the halo effect."

James Acaster, a comedian known for his stand-up shows, podcast 'Off Menu,' and television appearances, has joined the ranks of traitors in the current series. While TV presenter Maya Jama and actor Richard E. Grant were original traitors, Acaster's comedic background, according to Dr. Ross, could provide him with an edge.

Dr. Ross also highlighted confirmation bias, where individuals tend to favor information that confirms their existing beliefs, making it challenging to identify a liar once a decision about their innocence or guilt has been made. Conversely, celebrities perceived as abrasive might suffer from the 'horn effect,' leading to increased suspicion regardless of their actions.

Celebrity status itself can also create a hierarchy, potentially making lesser-known contestants hesitant to challenge more famous participants at the round table, even if their instincts suggest suspicion.

The psychologist added that even figures known for factual communication, like mathematician Hannah Fry, might benefit from a similar bias. "If you’re a big fan of Hannah Fry and her factual science communication, it’s going to be difficult to let yourself believe she could be lying to you," he wrote.
