He discusses some of the biggest questions in the nature versus nurture debate, including “Are we hard-wired to care about others?” Bloom points out why stereotyping can be both detrimental and beneficial, and he even explains what the porn preference of monkeys tells us about our own sexual choosiness, or lack thereof. After the hour is up you’ll understand why Bloom calls psychology, because of its cross-disciplinary nature, “the perfect liberal arts major.”

Paul Bloom is the Brooks and Suzanne Ragen Professor of Psychology at Yale University.
