• How Much Can Embryo Selection Increase IQ? | Dr. Jonathan Anomaly

  If you want to explore your own ability profile, you can take a free sample of the RIOT IQ test at https://www.riotiq.com.In this episode, Dr. Russell T. Warne speaks with Dr. Jonathan Anomaly about embryo selection, polygenic scores, and what modern genetics can predict about traits like IQ, health risks, and longevity. They talk through how polygenic scores are built, what kind of IQ gains are realistic when selecting embryos, why parents rarely choose the highest IQ embryo, and how people balance disease risks against cognitive traits.They also discuss validation studies, ethical concerns, CRISPR and gene editing, long term social effects, and what embryo selection might mean over several generations.If you want to watch the full video version, visit our YouTube channel at @RiotIQTest.

• The Ability That Predicts STEM Success Better Than IQ | Dr. Thomas Coyle

  If you want to test your own ability profile, you can take a free sample of the RIOT IQ test at https://riotiq.com.In this episode, Russell talks with Dr. Thomas Coyle about a surprising finding in modern intelligence research. 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

• The Truth About Polygenic Scores: What Your Genes Really Say About Intelligence | Yujing Lin

  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

• Hidden Talents Behind Bars: How Harsh Environments Reshape Intelligence | Dr. Michael Woodley

  What happens to intelligence when people face extreme environments like prisons? In this episode we talk with Dr. Michael Woodley of Menie about his recent paper, “The Reversal of Spearman’s Hypothesis in Incarcerated Populations and the Role of Non-Shared Environmentality.”We explore how one of the most established ideas in intelligence research completely reverses inside prison populations. Michael explains why harsh and unpredictable environments can trigger hidden talents and what that means for understanding IQ, cognition, and human adaptability.In this conversation we cover:What Spearman’s hypothesis really meansHow non-shared environments shape cognitive differencesWhy harsh environments can flip expected IQ patternsThe evolutionary explanation behind hidden talentsWhat this research means for testing and interpretationWatch the full video version on YouTube.

• The Hidden Problem in Every Classroom: Why Teaching by Age Doesn’t Work with Dr. Karen Rambo-Hernandez

  What does "grade level" really mean, and does it still make sense in today's classrooms?Dr. Russell T. Warne sits down with Dr. Karen Rambo-Hernandez from Texas A&M University to discuss new research showing that millions of students perform above or below their assigned grade. They explore how COVID-19 changed achievement in math and reading, why classrooms can span five to seven grade levels of ability, and what teachers can do when the system itself is not designed for such diversity.Should schools keep grouping students by age, or shift toward readiness and ability instead?Read Dr. Rambo-Hernandez’s paper: Millions of Students Are Still Above Grade Level : https://doi.org/10.1177/01623532241277840Watch the full video version on YouTube and subscribe: https://youtu.be/SenIUvVpLTQLearn more and take a free sample of the RIOT IQ Test → www.riotiq.comFind all our links here: https://linktr.ee/riottest
