This is adapted from a old economics article. Been searching for the exact reference to no avail. I'll try to find it and post it after the problem has been here a while.
Problem: The Island of Unfaithful Husbands
An island is inhabited by 365 couples. Now a special property of this island is that if a husband cheats on his wife, then an 'A' appears on the husband's forehead. This 'A' is plainly visible to everyone on the island except for the cheater's wife, which is lucky for him because if his wife finds out she will slit his throat while he sleeps.
Now everything is going hunky-dorey. All the husbands are cheating and each wife is clueless to her husbands infidelity, until one day . . .
A prophet from the mainland arrives on the island and pronouces,
Adultery has been committed upon this island!
The question is what happens next and why? There is a detailed answer.
