Delayed Development: 20-Somethings Blame the Brain

The Wall Street Journal:

Many parents of 20-somethings worry that their offspring haven’t yet found a career path, gotten married or become financially independent.

These parents should chill out, experts say.

Recent research into how the brain develops suggests that people are better equipped to make major life decisions in their late 20s than earlier in the decade. The brain, once thought to be fully grown after puberty, is still evolving into its adult shape well into a person’s third decade, pruning away unused connections and strengthening those that remain, scientists say.

“Until very recently, we had to make some pretty important life decisions about education and career paths, who to marry and whether to go into the military at a time when parts of our brains weren’t optimal yet,” says neuroscientist Jay Giedd at the National Institute of Mental Health, whose brain-imaging studies of thousands of young people have yielded many of the new insights. Postponing those decisions makes sense biologically, he says. “It’s a good thing that the 20s are becoming a time for self-discovery.”
