Contributor(s): Professor Paul Dolan, Professor Lord Richard Layard, Liz Zeidler | Welcome to LSE IQ, a new monthly podcast from the London School of Economics and Political Science. This is the podcast where we ask some of the leading social scientists - and other experts - to answer intelligent questions about economics, politics or society. In this episode, Joanna Bale investigates human happiness: why it eludes so many of us and what we can do about it. She talks to LSE’s Paul Dolan and Richard Layard, and Liz Zeidler of the Happy City Initiative.
