On this episode of Unsupervised Learning, friend of the podcast, Charles Murray returns to chat with Razib again. Murray has been a public intellectual and scholar since the 1970's. He is the author of Losing Ground, The Bell Curve, Human Accomplishment, Real Education, Coming Apart and What it means to be a libertarian and Human Diversity, among others. Born in 1943 in Newton, Iowa, Murray has a BA from Harvard, an MA and PhD from MIT, and did a 1960's stint in the Peace Corps in Thailand. He has held positions at the American Institutions for Research, the Manhattan Institute and the American Enterprise Institute.

More than four years after their last conversation, and seven years after his official retirement, Murray reflects with Razib on where he sees America going in the next decade, and what has surprised him about the last 25 years. Razib asks what it is like to be a long-standing "Never Trump conservative" and a libertarian in Trump's populist America. They also discuss the end of the "awokening" that began in the mid-2010s, and whether Murray's long exile from notice and acknowledgement from mainstream opinion-leaders and tastemakers is at an end. Murray also addresses the ideological fractures he sees on the right, and how America will deal with the last generation of mass immigration that has altered the US' demographic balance. They also discuss how taboo it still is to talk about group differences in cognitive performance, and whether America will be able to face the reality of demographics and the social consequences thereof in the 21st century.
