It is curious that physical courage should be so common in the world and moral courage so rare.
My book contains an obscene amount of references. What can I say? I love learning. Because of the replication crisis in psychology, I didn't want to write about a study or line of research, only to later discover that it wasn't actually valid. Here are some books that I repeatedly turned to (to view, the password is "research"):
