Mandatory Optimism and Cheerfulness

I recently stumbled across some great videos by RSA that animate lectures given by professors or talks given at conferences that discuss modern social phenomena.  Describing social phenomena has been one of the most challenging aspects of discplines that attempt to engage in understanding such phenomena (sociology, anthropology). The result is often large undigestable pieces of academic literature, or weak attempts to try to quantify this social phenomena force-fitting its significance into figures and statistics. 

The concept of institutionalized optimism is discussed in this video, but have a look at other videos that RSA puts out.
