The New York Times website regularly publishes a blog entitled Freakonomics, edited by Stephen J. Dubner. This week, Dubner asked six individuals how much progress they thought psychology and psychiatry had made in the past century. The participants were developmental molecular biologist John Medina, psychiatry professor Peter D. Kramer, a woman who recently lost her depressed son to suicide named Laurie Schwartz, behavioral economist Dan Ariely, historian of psychology David B. Baker, and evolutionary psychologist Satoshi Kanazawa. The assessments are universally upbeat, but for somewhat different reasons.
