Kelly McGonigal: How to make stress your friend
I fully agree with Karen Raymer's criticism that Dr. McGonigal is using correlative data to infer causality. Even the authors of the paper she cites (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3374921/) write that: "In addition, reverse causality may partially explain the findings in this study. Adults who reported poor health may have been more likely to report that stress impacts their health simply due to their poor health status; moreover poor health status could also have influenced the amount of stress reported. The cross-sectional nature of these data precludes us from examining the direction of causality among the amount of stress, the perception that stress affects health, and health outcomes."
