I remember working for a manufacturing company where I drove a forklift (during the summer).
One of my most vivid memories is walking into the breakroom and seeing on the television a scrolling banner that declared homosexual couples were less likely to have children than heterosexual couples.
And I remember everyone in that room laughing their asses off. And it's not as if no one in that room realized the reason for the study was so they could take into account things like adoption, etc. It's that the result was so obvious, even taking that into account, that it was amazing that someone was PAID to come to a conclusion that everyone knew without the money.
And this is the crux of the problem with "science". It wants to be "interesting", so it will literally try to drum up something against what "everyone knows".
So the idea that what everyone over generations "knows" is generally more applicable than "science" is not surprising at all.
