The first part of the article contrasts running against sports that stress hand-eye coordination and decision making. The author claims that the connection between those sports and overall cognitive performance is more obvious. But the scientific study only compare runners against sedentary people. We don't know how running compares to basketball, etc. on these metrics. The running/cognition correlation is presented as surprising, but it would be a lot less surprising if a stronger version of the same link existed for decision-based sports. The speculation about running->cognition causality should be kept to a minimum until there is data on other sports for comparison.
