How U.S. Public Health Has Strayed From Its Liberal Roots

In this interview, based on her landmark book, Why Trust Science?, historian of science Naomi Oreskes offers a bold and compelling defense of science, revealing why the social character of scientific knowledge is its greatest strength — and the greatest reason we can trust it. Drawing vital lessons from cases where scientists got it wrong, Oreskes shows how consensus is a crucial indicator of when a scientific matter has been settled, and when the knowledge produced is likely to be trustworthy.

Political Correctness has formed the basis for a new intolerant mindset, actively policing speech that is deemed offensive or controversial. Rather than confront bad ideas through discussion, it has now become common to intimidate one’s detractors into silence.

In this conversation based on his new book, The Stupidity of War, political scientist John Mueller argues that American foreign policy since 1945 has been one long miscue; most international threats — including during the Cold War — have been substantially exaggerated. The result has been agony and bloviation, unnecessary and costly military interventions that have mostly failed. With international war in decline, complacency and appeasement become viable diplomatic devices and a large military is scarcely required.

Synthesizing relativity and quantum theory would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science. In this episode, Michael Shermer speaks with professor of theoretical physics Michio Kaku about: the Big Bang, black holes, worm holes, the multiverse, time travel, dark energy and dark matter, gravity, string theory, ETIs, meaning, and God.

Michael Shermer speaks with Jeff Hawkins, cofounder of Numenta: a neuroscience research company, about his new book A Thousand Brains: A New Theory of Intelligence in which Hawkins explains how simple cells in the brain create intelligence by using maplike structures to build hundreds of thousands of models of everything we know. Listen to this in-depth dialogue about the discoveries that allow Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought.

The concept of free will is profoundly important to our self-understanding, our interpersonal relationships, and our moral and legal practices. If it turns out that no one is ever free and morally responsible, what would that mean for society, morality, meaning, and the law? Just Deserts introduces the concepts central to the debate about free will and moral responsibility by way of an entertaining, rigorous, and sometimes heated philosophical dialogue between two leading thinkers.

For years, health organizations have preached the same rules for losing weight: restrict your calories, eat less, exercise more. So why doesn’t it work for everyone? The Case for Keto puts the ketogenic diet movement in the necessary historical and scientific perspective. It makes clear the vital misconceptions in how we’ve come to think about obesity and diet. Shermer and Taubes discuss: scientific consensus, nutrition, replication, why Newtonian mechanics doesn’t work with human bodies, the physics model of calories, complicating variables, intermittent fasting, which fruits and vegetables you should consume and avoid, cholesterol, heart disease, statins, and why it is okay to have bacon-and-eggs for breakfast.

Mine! explains these puzzles and many more.
