Ecklund vs Larson & Witham on Religion Among Elite Scientists

I'm interviewing Elaine Ecklund for Point of Inquiry today (the show airs Friday), and here's one thing I'm definitely going to ask her. Prior to Ecklund's study, the most prominently cited study of religious beliefs among elite scientists that I know of was by Edward Larson and Larry Withham in Nature in 1998.
