In this talk, based on her new book of the same name, psychologist Melanie Joy explains the psychology that causes us to believe that certain individuals and groups are more worthy of being treated with integrity than others. She explains the mentality that underlies oppression and abuse and which can cause advocates for compassion and justice to engage in the very behaviors they`re trying to transform. Dr. Joy also talks about how to use this understanding to help create a more empowered movement for animals.
