The Human Intelligence Podcast

How intelligence shapes the prosperity of nations and why immigration policy can have long-term economic consequences? The conversation with Dr. Garret Jones explores the research behind national intelligence, cooperation, and economic growth. Garret explains how the average cognitive ability of a population influences productivity, institutional quality, and long-term development. We also discuss how immigration patterns interact with these dynamics and why the composition of immigration may matter more than the raw number of migrants. We also examine historical and modern examples that illustrate these patterns, including how immigration influences economic performance, how shared environments affect productivity, and why debates around diversity and immigration are often oversimplified in public discourse. Topics covered in this episode: – How intelligence affects national prosperity – Why some countries become richer than others – The relationship between immigration and economic growth – Selective immigration and high-skill migration – How shared environments influence productivity – The historical case of Argentina’s economic decline – Why the effects of diversity can vary across social groups This is part of the RIOT IQ Podcast, where we explore intelligence, cognition, and human potential through science, data, and serious conversation.

n this episode of the RIOT IQ Podcast, we talk with Dr. James J. Lee about why IQ is still widely misunderstood and how intelligence researchers actually think about it. The conversation breaks down what IQ measures, what it does not, and why many public discussions around IQ miss the mark. James explains how researchers interpret IQ data, how prediction works in intelligence research, and where simplified narratives break down when applied to real-world outcomes. We also discuss how modern research approaches are improving the way intelligence is studied, how scientists think about general intelligence, and why understanding the limits of IQ is just as important as understanding its strengths. Topics covered in this episode: – What IQ actually measures – Common misconceptions about IQ – What IQ can and cannot explain – How intelligence researchers think about prediction – The limits of oversimplified IQ narratives – How modern research is refining our understanding of intelligence This is part of the RIOT IQ Podcast, where we explore intelligence, cognition, and human potential through science, data, and serious conversation.

In this episode, we sit down with neuroscientist Dr. Richard Haier to unpack what intelligence and IQ actually look like inside the brain. We talk about what decades of brain imaging research reveal about IQ, why higher intelligence is linked to more efficient brain activity, and what PET scans, genetics, and network models tell us about how intelligence works at a biological level.
We also explore common misconceptions about IQ, the limits of what training and environment can change, and what current science does and does not support when it comes to increasing intelligence.
This conversation focuses on evidence, not ideology, and draws from over 50 years of research in neuroscience and intelligence science.
Topics covered in this episode: – How IQ relates to brain efficiency – What PET scans reveal about intelligence – The Parieto-Frontal Integration Theory (PFIT) – Genetics, environment, and cognitive ability – Can IQ change over time? – What intelligence research actually shows

In this episode, Russell talks with Damien Morris about free will, genetics, and responsibility. They explore why genetic explanations for behavior are often misunderstood, what people get wrong about determinism, and how philosophical assumptions shape research in behavioral genetics, psychology, and social science.
Damien explains the idea of “free will by subtraction,” why ignorance cannot be the basis of freedom, and how different views of free will lead to very different conclusions about responsibility, inequality, and criminal justice. They also discuss why genetics does not erase agency and why philosophy still matters for understanding human behavior.
