Causation vs. correlation: Debunking a study targeting children of gay parents

Zach Wahls, author of “My Two Moms” and gay rights hero, and Will Saletan, a national correspondent for Slate, join “Viewpoint” host Eliot Spitzer to take a closer look at a study funded by two conservative organizations that found children of gay parents are less apt to succeed than those raised by heterosexuals. In a Slate article, Saletan argues that the study’s emphasis on the benefits of a stable home environment actually makes a case for same-sex marriage.

“This is a classic case of confusing causation and correlation,” Wahls points out. “You have the author of this paper trying to make the case that there is somehow this, you know, result that happens when you have a gay parent. But if you look carefully … if you actually look at the fine print, he says, ‘I don’t have a causal link.’ So essentially, this is the same logic where you could say ‘the eradication of pirates has caused global warming.’ He’s observing two kind of independent results without explaining why one might cause the other.”
