I ran across this little doozy of an article about teen brain development:
Neurological researchers around the country, spearheaded by Jay Giedd of the National Institute of Mental Health, have in recent years found that the brain is not fully developed until after 18. The brain system that regulates logic and reasoning develops before the area that regulates impulse and emotions, the researchers say.
"Adolescents are at an age where they do not have full capacity to control themselves," he [Temple University psychologist Laurence Steinberg] says. "As adults, we need to do some of the controlling."
While I am certainly pro-science, something about this attitude makes me very queasy.
As a thought experiment, simply substitude "African-Americans" or "hourly workers" for "adolescents." Not quite so innocuous anymore, is it?
