In the following video presentation, Harvard psychologist Dan Gilbert presents research and data from his exploration of happiness — sharing some surprising tests and experiments that you can also try on yourself.

The premise of his current research — that our assumptions about what will make us happy are often wrong — is supported with clinical research drawn from psychology and neuroscience. But his delivery is what sets him apart. His engaging — and often hilarious — style pokes fun at typical human behavior and invokes pop-culture references everyone can relate to.
