As a (substitute) school teacher, this topic is of special interest to me. What is intelligence? How is IQ calculated?
The National Public Radio program Radiolab recently aired a series of six programs entitled “G” that addresses general intelligence. The first program, broadcast on June 7, 2019, is “G: The Miseducation of Larry P” and explains why it has been illegal in California for the education system to give intelligence tests to black students.
If you’re interested in what happened to Albert Einstein’s brain, that’s “Relative Genius,” the third program.
All programs are available as podcasts at https://www.wnycstudios.org/podcasts/radiolab. It’s a fascinating series.
