Greg Smith Extended Interview
Video duration: 14:33
Greg Smith, senior researcher at the Pew Forum on Religion & Public Life, explains the findings of a survey on the religiously unaffiliated in America. "The religiously unaffiliated population is not wholly secular. It is wrong to think of them as consisting entirely of non-believers, for example. We know that many, if not most of them say they do believe in God," he says.
