Women Cooperative, Men More Cooperative

Most of us want to be nice. But is it all it's cracked up to be? It's a question that's been nagging at listener Tony in Illinois, USA, for over 25 years. While studying at university, the lecturer asked him whether competing or co-operating was the best strategy for success – essentially, does it pay to work together or should we sharpen our elbows and look after number one?

Nastaran Tavakoli-Far goes in search of answers. She talks to a local hero about why he puts his life on the line for others, and visits a neuroscientist to find out what happens in the brain when we help others. Her quest also leads her to question whether women really are the more co-operative sex and how an animal called a kudu might reveal how human co-operation evolved in the first place.
