Please. This is so forty years ago. Sitting in your Mother’s basement playing video games will do it, too. In fact, pick a parameter and look for something. Sloppy statistics and poor methodology and “presto”! Science, abused again. But then it is MSNBC. Consider the source.
The study was released yesterday: http://www.pnas.org/content/early/2014/11/05/1415297111.abstract
I am interested in your critique of the study methods and conclusions.
