Salem witch trials help explain why Faithfuls fail to spot real Traitors, says David Olusoga

Historical events like Spanish Inquisition show the velocity' at which rumours move to conviction, says Celebrity Traitors contestant

History might explain why Faithfuls find it so difficult to root out Traitors in the hit BBC show, suggests one member of the Celebrity Traitors cohort, who were record-breakingly bad at the game.

The roundtable - where contestants discuss who should be cast out - was somewhat frightening" because of the velocity in which something goes from a suspicion to belief, to faith, to condemnation", said the broadcaster and historian David Olusoga.
