It was one of my favorite actualized vids because it was spot on profile of some "political cultures" I'm familiar with and couldn't explain their origins. That took me on a path of exploring the idea of whole cultures in general as memes and memeplexes (e.g. politics married with religion etc.), which seems to me a continuation of genes and evolution, and religion as a big group coordinator (Haidt).
Which sources I should learn to pursue this further? It can't be a coincidence the idea of an ego in a person is such a perfect parallel of ego in an organization, I'm sure it was studied before.
