Another excuse for teenage laziness. Arnett does not back up his argument strongly enough. Could be a stage that adults go in and out of multiple times over the life course rather than restricted to after adolescence.
The biggest surprise about Emerging Adulthood is that it wasn't published by a trade press -- it should have been. Although also chock full of great research, this is a very accessible and engaging read. The interviews with young people are suburb, as are the illustrations and the surveys on important issues. The "Twixter" phenomenon of young people taking longer to find their way has been around for awhile, and this is the first book to really capture it in all its facets. The chapter on religion alone is worth the price of the book -- it cuts through media hype about growing fundamentalism to show that actually, most young people aren't all that religious. Parents or teachers, buy this book if you want to understand your twentysomething kids. Twentysomethings, buy this book to see that you are not alone.
