Cognitive Confidence

Today, we’ll hear from Dr. Dan Willingham, a Professor of Psychology at the University of Virginia. He’s taught there since 1992, and until about 2000, studied the neural basis of learning and memory. But today, all of his research concerns the application of cognitive psychology to K-16 education.

He’s the author of several books, including the best-selling Why Don't Students Like School?, and most recently, Outsmart Your Brain. His writing on education has appeared in twenty-three languages. In 2017 he was appointed by President Obama to serve as a Member of the National Board for Education Sciences. 

The transcript for this episode will be available the day after the airdate.

    The “For You” Algorithm

    In this episode, we're talking about how we consume, process, and share information—and how all of this is changing as our relationships with technology evolve. 

    Jason Lodge is the Director of the Learning, Instruction, and Technology Lab and Professor of Educational Psychology in the School of Education at The University of Queensland, in Australia. He explores the cognitive, metacognitive, and emotional aspects of learning, particularly in higher education and digital environments. He’s also an award-winning educator and advisor to the Australian Government on technology in education.

    Philipp Lorenz-Spreen leads the junior research group “Computational Social Science” within the Center Synergy of Systems at TU Dresden, in Germany. He and his team study the societal impact of digitalization, and how complex online discourse affects democracies worldwide.

    The Science of Yet | Wired for This

    Welcome to Wired for This—a deep dive into how we think, believe, change, and connect. In this limited series, we’ll explore the psychology of human behavior and neuroscience—what drives us forward, what holds us back, and how we navigate a world bursting with noise, contradiction, and complexity.


    Dr. Paul A. O’Keefe is a social psychologist and professor of organisational behaviour at the University of Exeter Business School. His research examines how psychological barriers—particularly beliefs about abilities, interest, and opportunity—shape the goals people pursue and their potential to achieve them. He and his team design growth-mindset interventions, tested through randomized controlled field experiments, to foster thriving in work, education, and health contexts. Dr. O’Keefe also directs the Mindsets & Motivation Lab and serves as an Associate Editor at Journal of Experimental Psychology: General.


    The transcript for this episode is available here.

    First Principles and Beyond

    Chris Pickard is a materials scientist who employs what are called first principles methods—modeling techniques that work out material properties using fundamental rules such as quantum mechanics and Newton’s laws. Trained as a condensed matter physicist, he refocused on materials science just as interest in the field was exploding amid advancements in computation. Switching between empirical and theoretical sciences was good preparation for a field that works closely with experimentalists and testers, and that is itself becoming more empirical under the influence of machine learning. Pickard spoke with American Scientist associate editor Nicholas Gerbis about his early successes in studying hydrogen under high pressure, and his hopes for the future of his field. This interview has been edited for length and clarity.
