The village Problem
Once upon a time there was a small village, the population only consisting of married couples who were very gossipy. Everybody told everybody about the affairs that men might have with other women. There was only one exception however, nobody would tell a man about the infidelity of his wife, because if a man KNOWS about the infidelity of his wife, he is going to divorce her the following morning.
One day a traveller came to the village and spent some time in it, listening to all the gossip. After some days, he called for a village meeting and told the whole population the following.
"There is infidelity in this village"
Then he left.
Assuming the population of the village is really clever, what is going to happen and why?
