Why Do They Vote That Way? by Jonathan Haidt

Combining moral‑psychology research, interviews and experiments, the book argues that liberals and conservatives rely on different moral foundations—such as care and fairness versus loyalty, authority, and sanctity—which shape political judgments; it shows how emotions, intuitions and group identities often drive voting behavior more than deliberate reasoning, examines how messaging and social networks reinforce partisan loyalties, and suggests ways to reduce polarization by understanding opponents’ moral concerns and reframing appeals accordingly.
