EconTalk Russ Roberts

When physician Walter Freeman died in 1972, he still believed that lobotomies were the best treatment for mental illness. A pioneer in the method, he was a deeply confident and charismatic man who eagerly spread the technique in America, long after the rise of alternative treatments that were less destructive. Listen as journalist Megan McArdle and EconTalk's Russ Roberts discuss what McArdle calls the "Oedipus Trap": mistakes that no one can live with, even if they were innocently made, and how admitting such mistakes to ourselves is nearly impossible.

Tolkien read it as a tale about mortality. The poet David Whyte said it was a metaphor for the psychological demons deep in our minds. And that, insists the cartoonist and writer Zach Weinersmith, is precisely Beowulf's appeal: Its richness opens the door to endless interpretation. Listen as the author of Bea Wolf, a graphic novel for children based on the Old English poem, speaks with EconTalk's Russ Roberts about poetry in general, Beowulf in particular, whether we should require students to memorize poems, and the value of stories for children even without a moral lesson.

Since at least Adam Smith, the common wisdom has been that the transition from hunter-gathering to farming allowed the creation of the State. Farming, so went the theory, led to agricultural surplus, and that surplus is the prerequisite for taxation and a State. But economist Omer Moav of the University of Warwick and Reichman University argues that it wasn't farming but the farming of a particular kind of crop (but not others) that led to hierarchy and the State. Moav explains to EconTalk host Russ Roberts storability is the key dimension that allows for taxation and a State. The conversation includes a discussion of why it's important to understand the past and the challenges of confirming or refuting theories about history.

Do psychologists know anything? Psychologist Paul Bloom says yes--but not the things that you might think. Bloom discusses his book Psych with EconTalk's Russ Roberts and what the field of psychology can teach us about human intelligence, consciousness, and unhelpful instincts. They also discuss just how far psychology is from a true understanding of the human mind, and why, according to Bloom, that might not be such a bad thing.

When psychiatrist Marco Ramos of Yale University prescribes antidepressants to patients in distress and they ask him how they work, Ramos admits: We don't really know. And too often, they don't work at all. Despite decades of brain research and billions of dollars spent, psychiatry has made little progress in understanding mental illness. Listen as Ramos explains to EconTalk's Russ Roberts how the myth of the biological basis for mental illness began, why it stubbornly persists, and why honesty about what we know and don't know is the best policy.

Psychologist Adam Mastroianni says peer review has failed. Papers with major errors make it through the process. The ones without errors often fail to replicate. One approach to improve the process is better incentives. But Mastroianni argues that peer review isn't fixable. It's a failed experiment. Listen as he makes the case to EconTalk host Russ Roberts for a new approach to science and academic research.
