That was much harder to do, in the past, and people back then weren't as foolish and trusting as today. They literally went to great lengths to make sure it did

  > That was much harder to do, in the past Is there any evidence for that? In one of David Attenborough's documentaries, he talks about that. Research showed that people are quick to point out that a baby looks like the father, even when the father isn't the biological father. The inference is that cuckolding is a common occurrence. You're right that people would go to great lengths to ensure fidelity of the women, even executing them for infidelity. They wouldn't have bothered if cuckolding wasn't common. The recent movie "The Last Duel" was historically accurate in that it was a duel to the death over whether a knight's friend had sex with his wife or not.
