It's hardly an original idea.  I've wondered about it myself, and I doubt I'm alone in that.  Is it possible or likely that modern science and technology have made it possible for members of our species who are less robust from a survivability standpoint -- however you choose to define or measure that -- to survive and propagate, and in doing so move the overall numbers downward?

Purely anecdotal and so conclusive of nothing, I am a walking example of the question.  I carry not one but two genetic defects that, probably before the industrial revolution and almost certainly before the agricultural revolution, would have severely curtailed my expected life span.  And in so doing, substantially lessened the likelihood that I would have produced offspring, and if I had that I would have lived long enough to ensure that they got a good start in life and so lived to reproduce themselves.

For me the question is not academic.  I have wrestled with the ethics of possibly passing on those defects to my two sons. In my case the question is not lessening of intelligence -- we all seem to score a smidge above average on the typical mental aptitude tests -- but on the issue of physical robustness.  I wouldn't have made it through adolescence as a paleo bison hunter.  Probably not much past it as a neolithic agriculturist.  So, am I contributing, not to the dumbing down but maybe to the wimping down, of the human gene pool?

Now where are we going and what's with the handbasket?

Google Scholar is nice in that it allows people to search academic papers quickly, but it seems sort of clumsy.

How nice would it be to have a website that cataloged articles by independent and dependent variables, methodology, and the like?

I was thinking about the relationship between population density and political leanings, which I think would be hard to locate an article on using Google scholar as it stands now.
