Happiness by Design As a Professor of Behavioural Science at the London School of Economics, Dolan conducts original research into the measurement of happiness and its causes and consequences, including the effects of our behaviour. Here he creates a new outlook on the pursuit of happiness - it's not just how you feel, it's how you act. Happiness by Design shows that being happier requires us to actively re-design our immediate environment. Enough has been written on how to think happy. Happiness by Design is about how to behave happy and how to incorporate the most recent research findings into our everyday lives.
