re: #15 calochortus

I don’t disagree with you but at the same time I don’t think there is a nice pigeonholed explanation. People are shaped by their character which is shaped by their upbringing and probably to some extent their genes. Their upbringing includes their religious instruction. Some can be told they will go to hell if they don’t share their toys, and some will be told they go to heaven if they do.

This study investigates the end result, not the causes.
