This More or Less podcast episode investigates the rising autism diagnosis rates in the US. The host interviews a physician-scientist and a professor of cognitive neuroscience to explore the reasons behind this increase. The discussion highlights that the increase is not solely due to a rise in the actual prevalence of autism but also to broader diagnostic criteria, increased awareness, and improved diagnostic procedures. The episode also touches upon genetic and environmental factors contributing to autism, refuting claims by Robert F. Kennedy Jr. that paint an overly negative and inaccurate picture of autistic individuals and their potential.
