Twenty-two people enter a castle with the intention of lying, trusting, murdering and banishing each other. The format of the Traitors is now well established, but the celebrity version of the show highlights some interesting psychological biases.
In the standard version of the show (secret relationships aside) the contestants are all strangers. With no previous interaction, first impressions are even more important than usual, and will shape the game over the series. However, in the celebrity version, players will probably know others professionally, personally, or perhaps be fans of each other’s work before the game begins. All of this will affect their perception of others, influencing who they will trust and why.
