I'm interested in how people form valuations of the opinions of others. One domain to study is art. We have a long historic record of how the elite arbiters of taste have decided what artists and what artworks were great.

This is more relevant to 21st century American thought than many of you probably think. The defaults we assume, the stories that are told on television and in our movies, the things taught in our colleges, were partly determined by assertions made by continental philosophers and psychologists of the 18th through 20th centuries, most of which they just made up.

The process by which philosophers eventually get their views accepted into the Western canon looks the same to me as the process by which musicians or painters are accepted into or cast out of the Western canon. Neither has much to do with the quality of the product.
