It’s hard to stay hopeful these days. Stanford professor Jamil Zaki has been studying the incredible depth of human kindness for decades, but even he gives in to cynicism when he doubts our ability to be civil and cooperative. 

That’s a shame - because shedding cynicism and grasping hope will make you happier and healthier. Jamil and Dr Laurie Santos look at the scientific evidence showing that we should be more trusting of other people and optimistic about our facility to work together. 

Jamil's book Hope for Cynics: The Surprising Science of Human Goodness is out now.
