The Mozart Effect is the term for the idea that listening to classical music will improve your intelligence. The idea is baloney, and yet it enjoys wide belief. Check out MozartEffect.com, where Don Campbell sells a variety of products that will supposedly help people use music to improve their minds and bodies. The Skeptic's Dictionary has a good article debunking the phenomenon. Now Stanford researcher Chip Heath and his colleague Adrian Bangerter have published research tracking the evolution of the idea of the Mozart Effect. They trace The concept back to a 1993 experiment that found college students experienced a slight rise in IQ when listening to classical music (other researchers were never able to duplicate these results). From there the concept took off. But even though the original experiment involved college students, it didn't take long before people were applying the idea to infants and teenagers. So Heath and Bangerter came up with the hypothesis that "the legend of the Mozart Effect grew in response to anxiety about children's education." And "Sure enough, they found that in states with the most problematic educational systems (such as Georgia and Florida), newspapers gave the most coverage to the Mozart Effect." It seems like an interesting case study of what fuels the spread of misinformation.
