The WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous

I came across this Tsimane reference in this book. I got curious about Tsimane and found that they have been studied in Alcohol and Humans: A long social affair about how they share chicha, a local drink but not water as easily. Because of their lack exposure to The oxford handbook of critical concepts in music theory, they have been studied to understand the concepts of consonance and dissonance when not exposed to western environment. Healthy hearts have been another of their ahcievements.
