What’s the best way to investigate jealousy? In the lab, or on TV? Also, gossip: what is it good for, and how is idle chit chat linked to beauty? And why sharing Sunday lunch with mum and dad can make you broody.
Using footage from a TV show about cheaters caught out on camera, Barry Kuhle investigated sex differences in the causes of jealousy.
