It's probably that people who exercise eat healthier as well, and are less likely to spend their spare time drinking and doing drugs, which probably negatively affect grades.David Karphttps://www.blogger.com/profile/13710657164031182109noreply@blogger.comtag:blogger.com,1999:blog-38545607.post-56038269820954975242010-06-04T14:36:22.459+00:002010-06-04T14:36:22.459+00:00Yes, probably lots of important variables in this ...Yes, probably lots of important variables in this study missing but it's still an interesting one; especially since they control for study time. My main problem with this is their small sample size. <br /><br />What i'm thinking is that we have a much larger sample in our college data and some good personality measures, and other proxies, that might allow for more control..<br /><br />An RCT would be ideal.

So lazy people less likely to exercise and also less likely to study. <br />But it is an important issue. I propose an RCT - the Gold Standard in evaluation remember- where I randomly tell Geary PhD students to take a hike. Then, over a cool beer, Liam and I will calmly assess their academic performance.Kevin Dennyhttps://www.blogger.com/profile/17891633553910348880noreply@blogger.com
