RS 210 - Stuart Ritchie on "Conceptual objections to IQ testing"

Release date: June 10th, 2018

Stuart Ritchie

This episode features Stuart Ritchie, intelligence researcher and author of the book "Intelligence: All That Matters." Stuart responds to some of the most common conceptual objections to the science of IQ testing. Can we even define intelligence? Aren't there lots of different kinds of intelligence? How do we know the tests are measuring intelligence at all instead of something like motivation or familiarity with the style of testing? Does it undermine the meaningfulness of IQ as a metric that people can improve over time, with practice, or over generations?

Release date: May 27th, 2018

Christopher Chabris

This episode features cognitive psychologist Christopher Chabris discussing his research on "collective intelligence" -- why do some teams perform better than others at a wide variety of tasks? Julia discusses potential objections to the findings and how gender-related publication bias should affect our interpretation of them. In the second half of the episode, Julia and Chris discuss why people get so upset at companies like Facebook and OKCupid for doing experiments on their users, and whether that's fair.

RS 208 - Annie Duke on "Thinking in bets"

Release date: May 13th, 2018

Annie Duke

This episode features Annie Duke, former pro poker player and author of the book Thinking in Bets: Making Smarter Decisions When You Don’t Have All the Facts. Julia and Annie debate why people tend to ignore the role of luck in their decisions, whether expressing uncertainty makes you seem weak, and how people end up engaging in "defensive decision-making," where they're not trying to make the best call so much as simply avoid being blamed for bad outcomes.
