We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
There aren't that many comprehensive scientific studies simply because of the cost, complexity, and time involved. Most so-called "studies" are in fact data dredges from the massive database of legitimate studies. And most of these are aimed at some conclusion that the original study never considered or was designed to identify. Simply put a data dredge is a search of all the data looking for the conclusions you desire and ignoring or throwing out any results that disagree with your goal. It isn't suprising then that it is rare that these "studies" results can be replicated and later turn out to be false and useless.
