Yoram Hazony discusses his book, The Virtue of Nationalism, with EconTalk host Russ Roberts. Hazony argues that nationalism, for all its flaws, is a better system than a global system of governance. He argues that while the competition between nationalist states can lead to violence, the opportunity for each nation to pursue its own policies creates the benefits that trial-and-error innovation create in the marketplace. He also points out the dangers of global government systems and argues that U.S. military dominance and various international institutions such as European Union and the International Criminal Court have been growing in power.

Psychologist Charlan Nemeth of the University of California, Berkeley and author of In Defense of Troublemakers talks with EconTalk host Russ Roberts about the ideas in the book--the power of groupthink, the power of conviction, and the opportunity for an authentic, persistent dissenter to have an impact on a group's decision. The conversation concludes with a discussion of the challenges of doing careful research in modern times.

Political scientist Lilliana Mason of the University Maryland and author of Uncivil Agreement talks about the book with EconTalk host Russ Roberts. Mason argues that political partisanship has become stronger in America in recent years because it aligns with other forms of community and identity. People are associating primarily with people who share their political views in their other social activities outside of politics. As a result, they encounter fewer people from the other side. The intensity of partisanship can even overcome ideology as partisans change their policy positions in their eagerness to be on the winning side. The conversation closes with a discussion of what might be done to improve political discourse in America.

Physician David Meltzer of the University of Chicago talks about the power of the doctor-patient relationship with EconTalk host Russ Roberts. Meltzer, who also has a Ph.D. in economics, discusses a controlled experiment he has been running to measure the importance of maintaining the continuity of doctor-patient relationships. Meltzer argues that the increasing use of hospitalists--specialists who take over a patient from the patient's regular doctor once the patient is hospitalized--has raised costs and hurt patients. The initial results from his study show that patients who stay with their doctors have fewer subsequent hospitalizations and have better mental health. The conversation closes with a discussion of the challenges facing the current medical system to adopt cost-saving or life-improving technology or techniques.

Historian Frank Dikotter of the University of Hong Kong and author of Mao's Great Famine talks about the book with EconTalk host Russ Roberts. Dikotter chronicles the strategies Mao and Chinese leadership implemented to increase grain and steel production in the late 1950s leading to a collapse in agricultural output and the deaths of millions by starvation.

Alberto Alesina of Harvard University talks with EconTalk host Russ Roberts about how people in the US and five European countries perceive the population and characteristics of legal immigrants. Reporting on research with Armando Miano and Stefanie Stantcheva, Alesina finds that individuals systematically overestimate the number of immigrants while underestimating their standard of living. His research also finds that support for welfare payments to the poor is related to the perception people have of the size of the immigrant population and their economic status. The conversation concludes with a discussion of why people's perceptions are so inaccurate and the implications of perception for public policy.

Teppo Felin of the University of Oxford talks with EconTalk host Russ Roberts about perception, cognition, and rationality. Felin argues that some of the standard experimental critiques of human rationality assume an omniscience that misleads us in thinking about social science and human capability. The conversation includes a discussion of the implications of different understandings of rationality for economics, entrepreneurship, and innovation.

EconTalk host Russ Roberts does a monologue on how political discourse seems to have deteriorated in recent years and the growth in outrage, tribalism, and intolerance for those with different views from one's own. Roberts suggests that part of the problem is the revolution of the market for information caused by the internet that allows people to customize what they see to fit their own political narratives and worldview. In short, the market for news works to make us feel good rather than to help us to discover the truth. The monologue closes with some suggestions for how we might improve the way we consume information and interact with those we disagree with.

Political Scientist and author Patrick Deneen of the University of Notre Dame talks about his book Why Liberalism Failed with EconTalk host Russ Roberts. By liberalism, Deneen means the modern enterprise--the push for self-actualization free of the constraints of tradition, family, and religion that typifies modern culture. He argues that both the left and the right have empowered the state and reduced liberty. He argues for a smaller, more local, more artisanal economy and a return to the virtues of self-control and self-mastery.

Economist and author Arnold Kling talks about the economic impact of culture and morality with EconTalk host Russ Roberts. Drawing on a recent essay on the importance of social interactions, Kling explores the role of culture and norms and their broad impact on economic life. At the end of the conversation, Roberts discusses the implications of human sociality for the way economics is taught and the way economists think about public policy.
