Effective Ad? Ask Your Brain

Science:

Companies and health organizations spend millions of dollars on surveys, polls, and focus groups trying to suss out what people will like, buy, or do. But research shows that these techniques aren’t all that accurate. Can brain scans do any better? It’s possible, according to a new study that finds that a neural activity predicts people’s responses to a public service ad about cigarette smoking better than simply asking a focus group.

Researchers led by neuroscientist Emily Falk at the University of Michigan, Ann Arbor, and Matthew Lieberman, a social neuroscientist at the University of California, Los Angeles, focused on the medial prefrontal cortex (MPFC), located at the front of the brain. Of the many roles its neurons play, scientists were most interested in the ones related to self-reflection, thinking of what you value, and identity. Activity in this region increases when people identify with what they see or try to determine the value of something as it relates to them. A previous study by Falk found that MPFC activity that was recorded while people viewed slides with messages urging regular sunscreen use predicted which individuals were most likely to comply. But Lieberman and Falk wanted to go a step further and see if activity in the MPFC in one group of people could predict the behavior of a much bigger population.
