Actually it looks like they wrote the title twice then dropped both copies in the blender to come up with something unique. "Beautiful men, women are more likely to have higher IQs" or "Beautiful men, women are smarter too" either of those I might have misinterpreted but understood, but the resulting title smoothie is just not coherent. Now on about the actual topic. Could this be an instance of correlation and not causation? Exercise is good for the brain. Exercise makes you look better. Therefore people who exercise both look better and are smarter on average.
