Default Interesting Example of the Placebo Effect

In a study that could make marketing managers and salespeople rub their hands with glee, scientists have used brain-scanning technology to shed new light on the old adage, "You get what you pay for."

Researchers from the California Institute of Technology and Stanford's business school have directly seen that the sensation of pleasantness that people experience when tasting wine is linked directly to its price. And that's true even when, unbeknownst to the test subjects, it's exactly the same Cabernet Sauvignon with a dramatically different price tag.

Specifically, the researchers found that with the higher priced wines, more blood and oxygen is sent to a part of the brain called the medial orbitofrontal cortex, whose activity reflects pleasure.

Brain scanning using a method called functional magnetic resonance imaging (FMRI) showed evidence for the researchers' hypothesis that "changes in the price of a product can influence neural computations associated with experienced pleasantness," they said.

The study, by Hilke Plassmann, John O'Doherty, Baba Shiv, and Antonio Rangel, was published this week in the Proceedings of the National Academy of Sciences.
