The Human Intelligence Podcast

In this episode of the RIOT IQ Podcast, we sit down with Charles Murray to explore some of the most debated and misunderstood topics in modern social science. We cover his recent books Taking Religion Seriously, Facing Reality, and Human Diversity, along with his most well-known work, The Bell Curve. The conversation moves from spirituality and meaning to intelligence, genetics, social class, and the role of science in understanding human differences. Murray shares his personal journey from agnosticism to a more nuanced view of religion, and explains why intellectual curiosity led him to explore questions far beyond policy and data. We also discuss the backlash surrounding The Bell Curve, what the research actually says, and why many of these conversations are still avoided today. This episode breaks down complex ideas around IQ, genetics, environment, and society in a way that challenges assumptions while emphasizing individual dignity and responsibility. If you’re interested in intelligence research, human behavior, or the intersection of science and society, this is a conversation worth engaging with.

In this episode of the RIOT IQ Podcast, we talk with Dr. Jennifer Jolly about how schools identify gifted students and whether the systems used to measure giftedness may be capturing personality traits rather than intelligence. The conversation explores new research examining teacher rating scales used in gifted education and asks an important question: are some of the tools used to identify gifted students actually measuring personality characteristics like conscientiousness or openness instead of cognitive ability? Jennifer explains how gifted identification works in many school systems, how teacher evaluations influence the process, and why distinguishing between personality and intelligence may be more complicated than it appears. We also discuss how intelligence develops in childhood, how early identification can shape educational opportunities, and why measurement methods matter when schools decide which students receive advanced academic support. Topics covered in this episode: – How schools identify gifted students – The role of teacher rating scales in gifted education – Whether personality traits influence gifted identification – The difference between intelligence and personality – How intelligence develops during childhood – The challenges of measuring cognitive ability in schools – Why measurement methods matter for educational decisions This is part of the RIOT IQ Podcast, where we explore intelligence, cognition, and human potential through science, data, and serious conversation.

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 This is part of the RIOT IQ Podcast, where we explore human intelligence through science, data, and serious conversation.

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.Read the article discussed in this episode: https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/behavioral-genetics-and-human-agency-how-selectively-deterministic-theories-of-free-will-drive-unwarranted-opposition-to-behavioral-genetic-research-and-undermine-our-moral-and-legal-conventions-part-i/EF9614F273F0F07150C5DBB29F1DF1D8If you want to watch the full video version of this episode, visit our YouTube channel: https://www.youtube.com/@RiotIQTestLearn more about the RIOT IQ test at https://www.riotiq.com.

There is an ability that predicts STEM success better than IQ, and most people never hear about it.Dr. Coyle explains what this ability is, how it develops during adolescence, and why schools rarely teach or measure it. They also cover spatial and mechanical skills, processing speed, sex differences, and why these patterns matter for future engineers and technical careers.This is a simple and clear conversation that shows how different abilities shape real outcomes beyond a single IQ score.Watch the full video version on our YouTube channel: https://www.youtube.com/@RiotIQTestLearn more about the RIOT IQ test: https://riotiq.com

In this episode, Dr. Russell Warne talks with Yujing Lin from King’s College London about her new open-access study on polygenic scores and cognitive abilities. The conversation explains how polygenic scores work, why they predict IQ and education so well, and what changes when you compare unrelated individuals to siblings raised in the same family.We explore how genetics and environment interact, why socioeconomic status matters at the family level, and why between-family effects are real signals rather than bias. The discussion also covers missing heritability, additive genetic effects, and why the same genetic variants influence intelligence across the full normal range.If you’re curious about what modern behavioral genetics really shows about intelligence, this episode gives you a clear and data-driven explanation.Read the full study here: https://icajournal.scholasticahq.com/article/140654-polygenic-score-prediction-within-and-between-sibling-pairs-for-intelligence-cognitive-abilities-and-educational-traits-from-childhood-to-early-adulthoodTry a free sample of the RIOT IQ Test → https://www.riotiq.com Follow us on X → https://x.com/RiotIQ Find all our links → https://linktr.ee/riottestWatch the video version on YouTube: https://www.youtube.com/@RiotIQTest
