I'm genuinely surprised someone could read that whole blog post (I'm assuming here) and come away with that conclusion. Gelman addresses this so directly in the article:
"Recall the Javert paradox. It’s completely reasonable to write about scientific misconduct, and yes sometimes we have to scream a bit to get heard over all the chatter of the scientist-as-hero press."
...
"But we need real expertise, not fake expertise. I’ve said it before and I’ll say it again: Gresham, baby, Gresham. If we don’t contest the fake expertise, I’m seriously worried it will be crowding out the real stuff."
There is good research and there is bad research. The latter should not be given a pass just because all research has some amount of bias.
