I applaud your special on the science of happiness. However, the issue would have been more complete had it mentioned the idea of viewing economic development policies in the context of "gross national happiness" or GNH. This concept is based on the recognition that gross national product does not accurately reflect the well-being of a nation. GNH is a bold idea with far-reaching effects. Since happiness has a scientific base, it can be developed and promoted on a larger social scale.
