I'm watching season 1 (no spoilers please).
I don't think that being emotional is necessarily a bad thing.
And perhaps the contestants on one season of a gameshow are not a statistically significant sample size...
But observing the men and women on the show, the men are far more emotional. They cry, they get angry, they are excitable, they sulk, they form close bonds, they trust, they are gutted when betrayed. The women are far more dispassionate and able to respond rather than react.
If I were an alien observing the human race via season 1 of Traitors my field notes would show that men were by far more emotional than women.
