Rationally Speaking #29 - Q&A Live!

In a continuation of episode 28, Massimo and Julia sit down for a Q&A session in front of a live audience at the Jefferson Market Library in New York City. The audience's questions include whether economics and evolutionary psychology are really science, what's the deal with the placebo effect, the influence of corporate money on scientific research, and how can some scientists publish legitimate research and still believe in pseudo-science. Also, vegetarianism: is it about science, ethics, or both?
