This reminds me of a blurb that I happened to see in WebMD magazine a month or so ago. It said that working moms needn't worry about their children, because a study found that children of working moms actually fare better than children of moms who stay at home.
The study was clearly garbage, yet WebMD took its results for granted. So I reserve the right to ignore studies that clearly contradict what common sense tells me. On the other hand, if a study tells me that harm will come to people if I do something, and then I still do it a la Obama, then there may be a problem with my belief system.
