I'd like to read the whole study as media reports and the authors' abstract leave a lot of important information out. The abstract mentions that "Early adolescent pseudomature behavior predicted long-term difficulties in close relationships, as well as significant problems with alcohol and substance use, and elevated levels of criminal behavior."
How does being "cool" at a young age relate to adulthood income levels, adult home ownership likelihood, adult education level, income level of parents, etc.? Do any of the problems with alcohol, narcotics, or "criminal behavior" actually affect the kids 10 years out of college? Or is it simply that these kids have more freedom during high-school and college years, which allows them to find "trouble," but they are able to eventually settle back into "normal" upper-middle-class lives afterwards?
Numerous studies show that engagement in deviance does not affect or stigmatize the wealthy the same way it does for the poor. I'm skeptical of the media's announcement that "the cool kids become losers," as I doubt this is true. For example, look at guys who join frats, are they more likely to have alcohol, and substance abuse problems compared to their college peers? Who is more likely to a salary above the median wage post-college frat guys or the average college kid with that holds the same degree as their frat peer?
Alcoholism, substance abuse, and even engagement in some "criminal" activities certainly does not make one an economic "loser."
