As a society today, intelligence is something highly valued. The society is so competitive. Life, Education, Jobs are all places where IQ seems to be the most important factor, the make it or break it thing. Everybody wants to be as smart as possible, and if there are short cuts to increasing intelligence people want to know. But is the constant quest for easy ways to increase people's IQ just increasing the amounts of extraordinary claims?
The Mozart Effect is the claim that IQ increases after listening to classical music. Is there extraordinary evidence for this extraordinary claim? There are no definite results that this is true. The areas in the brain that are activated when listening to this type of music is the prefrontal and temporal regions. These regions are involved in music processing. Therefore, they suggest that this would prime areas involved in spatial reasoning. The enhancement at the most in studies lasts about 12 minutes. Many other studies there is no difference. Some studies have found that there's a temporarily increase of cognitive skills, but other studies have found no evidence of this effect. Since the replicable studies don't always have statistical evidence, there is no extraordinary evidence to back up the claim of the Mozart Effect.
Like many extraordinary claims, the media got involved and made up a pseudoscience. They made an industry out of it. They promote the unverified claims; yet continue to make a lot of money out of. It's not surprising that people are so quick to buy this though. Who doesn't want instant an increase of intelligence?
