Sigh, what isn't biased these days? No need to poison the well, the article is clear and sound (to me at least) regardless of who wrote it and why. Do you have any arguments against it? Or your own better analysis of the two studies?
It really annoys me how people disregard what "the other side" is saying just because it's them saying it. Just adds to the polarization. And it annoys me because I used to do the same.
