Teaching reasoned decision-making to teens backfires

From 10 Ways We Get the Odds Wrong by Maia Szalavitz
Teens may not be irrational about risk but too rational, argues Valerie Reyna, a psychologist at Cornell University. Adults asked to consider absurd propositions like "Is it a good idea to drink Drano?" immediately and intuitively say no. Adolescents, however, take more than twice as long to think about it. Brain-scan research shows that when teens contemplate things like playing Russian roulette or drinking and driving, they primarily use rational regions of the brain—certain regions of cortex—while adults use emotional regions like the insula.

When risky decisions are weighed in a rational calculus, benefits like fitting in and feeling good now can outweigh real risks. As a result, teaching reasoned decision-making to teens backfires, argues Reyna. Instead, she says, we should teach kids to rule out risks based on emotional responses—for example, by considering the worst-case scenario, as adults do. But research suggests there may be no way to speed up the development of mature decision-making. Repetition and practice are critical to emotional judgment—which means that it takes time to learn this skill.
