Over the past three decades, Paul’s research in health economics and behavioural science has focussed on an array of issues, including valuing health states, equity in health, valuing safety, the impacts of COVID-19, social mobility, the theory and practice of nudging, and the use of financial incentives. The glue that has held this all together is developing tools to better capture the richness of the human condition for the purposes of individual, corporate and policy decisions.

Paul’s research has had significant impact. He is author of ‘Mindspace: Influencing behaviour through public policy’ published by The Institute for Government in March 2010 and he wrote the questions that are used by the ONS in the UK to monitor national wellbeing. His 120-odd academic papers have been cited more than 36,000 times.

He is author of the Sunday Times best-selling book “Happiness by Design”, and “Happy Ever After” and his latest book is "Beliefism: how to stop hating the people we disagree with". He is creator and presenter of the podcasts “Breaking Beliefism”, "Duck - Rabbit" and "Get Happier". He is also the Founder of the Lifetime Wellbeing Cooperative™.
