Fake news can travel faster and lodge itself deeper in the mind than the truth. Fact-checking comes too late and lies have already spread like a virus. Claudia Hammond investigates a new approach to pre-bunking misinformation via social media by inoculating the mind through exposing people to a mild dose of the methods used to disseminate fake news.

How underrated is humour? According to Stanford Business School researchers Jennifer Aaker and Naomi Bagdonas, authors of Humour Seriously, the frequency at which we laugh or smile drops rapidly from the age of 23 and the workplace is to blame.

People with anxiety or depression are increasingly being prescribed spending a certain amount of time in nature. But are so called Green Prescriptions right for everyone? Mathew White of Exeter University discusses his new research that reviews 166 studies which suggest that for some, a walk in nature may be more of a chore than a joy. Could the strong psychological beneficial effects be achieved with a dose of virtual reality instead?

Claudia Hammond’s guest is Daryl O’Connor, Professor of Psychology at the University of Leeds.
