Guests: Judith Wallerstein Co-Author, The Unexpected Legacy of Divorce (Hyperion, 2000) Should a couple stay together for the sake of their children? For 25 years, Judith Wallerstein has studied a group of Californians who all lived through their parents' divorce. She found that the lingering effects of their parents' breakup still effects them in profound ways. Other researchers dispute her findings. Join Juan Williams and Judith Wallerstein for a look at the long term effects of divorce on kids, on the next Talk of the Nation, from NPR News.
