"Freakonomics" co-author Stephen Dubner appeared on Thursday's "Good Morning America" to talk about crime and also to repeat his unsubstantiated argument that legalized abortions have resulted in less crime. The journalist and author asserted, "What happened when Roe V. Wade was handed down was that unwanted children are basically at a much greater risk for being born into the circumstances where they're more likely to lead a criminal life. Not every unwanted child by a long stretch, but typically."

In other words, 35 years after the Roe V. Wade Supreme Court decision, "the generation of people around then included fewer unwanted children and therefore fewer criminals." At no point did Roberts question this assertion or mention that it has been repeatedly challenged since Dubner and his economist co-author Steven Levitt made it in their book. In fact, a study by another economist, John Lott, found that legalized abortion actually increased the murder rate by seven percent. However, unimpeded by contradictory arguments, Dubner simply told Roberts, "It's good to know what forces work in society, if for no other reason than to keep doing the right thing." The right thing, one presumes he means, is to keep aborting children.
