David Pizarro is an associate professor in the department of psychology at Cornell University. His research focuses on how and why humans make moral judgments (such as what makes us think certain actions are wrong, or that some people deserve blame or praise for their actions). He’s also interested in how emotions—especially disgust—influence a wide variety of social, political, and moral judgments.

Tamler Sommers is an Associate Professor of Philosophy at the University of Houston. He teaches primarily in ethics, political philosophy, and the philosophy of law, specializing in issues relating to free will, moral responsibility, punishment, and revenge.
