Intelligent Decline

I'm not quite sure what I'm going to do with this. But the phrase caught my ear and imagination with its concise summary of a possibly post evolutionary effect of civilization. IE civilization leads to a decline in the quality of the genetic pool in so far as selective pressures are removed, mitigated, cured, treated, or otherwise have their impact reduced. Thus the rise of intelligence/civilization eventually leads (inevitably?) to it's own decline.
