As Joanne pointed out, only one country, tiny between China and little Bhutan, wedged Gross National India, has adopted central index of happiness as the government policy and actually has a good deal of success in education and in health and economic growth and environmental preservation. They have a rather sophisticated way of measuring the effects of different policies on people's happiness. They are the only country to go that far. But you are now beginning to get other countries interested enough to do kind of white paper policy analyses of happiness research—what effects would it have if we used it more for public policy? You are beginning to get countries like Australia, France, Great Britain, that are considering publishing regular statistics on happiness. So it is beginning to become a subject of greater interest for policymakers and legislators in different advanced countries.
