A visual history of human knowledge

I am a HUGE fan of data visualization and network theory and analytics. I think these techniques, when applied to intelligence test data, could provide us much more important insights than the continued use (misuse?) of linear SEM/CFA models. Network visual models are elegant...and more reflective of "reality".

This is a very good TED talk.
