The IQ test is supposed to be a measure of human intelligence. But is it? Today, we're joined by UC Berkeley professor Dr. Steven Piantadosi to understand why the diversity of human intellect can't be captured by a single number. We'll explore the history of IQ, from its innocent beginnings in French schools to its dark role in the eugenics movement. We'll understand why IQ testing is fallible, thanks to rising scores, the effects of motivation, and cultural bias, and learn about a test in the 1970s that was designed to flip that bias upside down. Go full galaxy brain and tune in to hear why IQ isn't all it's cracked up to be.
