hurricane harvey, intelligence, iq, neuroscience, race
It’s Part 2 of the Patreon listener selected episode! David and Tamler continue their discussion on intelligence from our last episode by tackling the radioactive topic of group differences and IQ. Are there reliable differences in IQ across races? Given that IQ is strongly heritable, and that racial categories are based (in part) on biological differences, does it follow that group differences in IQ are due to biological differences across racial groups? (Could only a politically motivated science-denier conclude otherwise?) David argues that biological explanations for racial differences in IQ are based on a fundamental misunderstanding of genetics and race. It’s a complex argument, so if you start listening, please finish! (Oh and @VBW_No_Context on Twitter, take a vacation, you’ve earned it!). Plus, more on neuroscientific explanations, and Tamler relates his experience of Hurricane Harvey.

cognitive neuroscience, dogs, fmri, intelligence, iq
David and Tamler do their best to talk frankly about intelligence and IQ research. (It's our Patreon listener-selected topic! We probably would never have chosen this one on our own...). Is intelligence a meaningful, definable concept? Can we reliably test for it? How much of the variability in IQ across individuals is due to heritable factors? Are people with higher IQ happier, wealthier, or healthier than people with lower IQ? And why is this topic so controversial anyhow? Plus in the intro segment Tamler and David discuss why you probably don't need fMRI to know what your dog wants, and why cognitive neuroscience seems to confuse otherwise intelligent folks. (Note: This is Part 1 of our discussion on intelligence. In Part 2 will delve into the slightly more controversial topics of IQ, race, and gender).
