Alison Gopnik's Wall Street Journal article "What's Wrong With the Teenage Mind?" was published a month ago, but you should still read it.
The piece touches on numerous recent research in developmental psychology, neuroscience, and other cognitive studies that indicate an increase in the length of human adolescence. That is, puberty starts earlier and adulthood arrives slower than your bus.
Gopnik's piece isn't a unified theory of why 30-year-olds still live with their parents, but she makes an interesting case for a gradual shift in our culture that has triggered a shift in our brains.
