We start with the recognized positive correlation between citizen health and citizen I.Q.
This subject has been broached, cautiously, in a number of domestic general-readership publications, but knowing that they would be dismissed by a majority of Addison Eagle readers as identifiably infected with a conservative bias, your humble scribe hose to cite a pair of academic publications instead.
One is a collaborative effort between the Universities of Delaware and Edinburgh, in which authors Gottfedson and Deary document the epidemiological fact that "Intelligence Predicts Health and Longevity."
The second is similarly European in origin: the February issue of the European Journal of Cardiovascular Prevention and Rehabilitation. It's on the web at www.physorg.com, where you can read that "I.Q. is among the strongest [negative] predictors of cardio-vascular disease..." and "...lower I.Q. scores could elevate cardiovascular disease risk, notably the application of intelligence to healthy behavior [choices..." and (viewer discretion advised) "...I.Q. may well be one important factor behind the place of social class as a fundamental determinant of inequalities in health...more so than access to[health-care] resources ...a low I.Q....as suggested in this study, may be a further independent explanation."
In layman's language, smarter people are statistically predictable to make smarter personal life-style and wellness choices than not-so-smart people. So, inquiring minds want to know, what's the correlation between smartness and wellness, not just at the individual statistical level, but at the state level? After all, it's now the sStates which, as "laboratories of democracy" in the famous words of the progressively-politically-oriented Justice Louis Brandeis, are designing and adopting a variety of health-care plans. Such state smartness rankings are readily available.
You'll see one such ranking on the wesite of "The Audacious Epigone" (test your college classics major on definition) where you'll see Massachusetts, New Jersey, and Vermont in the top three, with I.Q.s in the 101-102 range, and New Mexico, Michigan, and District of Columbia in the bottom three, with I.Q.s in the 91-94 range.
