51. What Separates Humans From Other Animals?

In this episode of "No Stupid Questions," Angela Duckworth and Stephen Dubner delve into the topic of animal intelligence, sparked by a study on pigs playing video games. They discuss what, if anything, truly distinguishes humans from other animals, referencing insights from theologians, sociologists, and the concept of speciesism. They also explore the ethics of eating animals, vegetarianism trends, and personal moral conflicts related to meat consumption. Later, they address a listener's question about pacing during phone calls, reframing it as a potential stress reliever and cognitive aid, while also discussing the benefits of walking and the nature of stress itself.
