Infidelity is seen as the ultimate betrayal, and many relationships are brought down by it. Around the world most of us agree that it’s wrong for a married person to have an affair, but that doesn’t seem to stop us: why? The answer could lie in our DNA. In this week’s Why Factor, Phoebe Keane hears how research into the mating habits of prairie voles could shed light on the extra marital affairs of humans and explores how we make decisions in the heat of the moment.
