Mathematician Hannah Fry is bringing serious number-crunching to the Celebrity Traitors castle
She has studied previous series to identify recurring behaviour among the secret Traitors, including contestants casting deliberately isolated votes early in the game
Fry says her approach draws on the logical methods associated with Alan Turing, although she admits the Faithfuls’ chaotic decisions may make useful clues difficult to spot
Her competitive streak could be another challenge
Fry would prefer to play honestly as a Faithful, while fans suspect her forthcoming UK tour may signal a strong run on the BBC series.
