Is Brendan Nyhan a trustworthy source? (University of Michigan, health policy)

Brendan Nyhan is, per him, the "RWJ Scholar in Health Policy Research at the University of Michigan" and a "political scientist and media critic." Can you trust what he writes? Perhaps in an academic context, but on his blog he's willing to disable "peer review" by deleting comments. When a site delete comments you can't trust anything they write: they've disabled fact checking by their readers. That means that you can't trust anything that Brendan Nyhan writes at his blog: you'll never know when he's deleted a comment showing how he got something wrong.

And, in this case, I wasn't even disagreeing with him that greatly, simply providing additional information. I left the comment below on the post "Goldberg on birther/truther coverage" (brendan-nyhan.com/blog/2010/05/

Scroll past the summary and take a look at some of my dozens of posts about this issue:

1. Once you actually look at (and take the time to think through) the HI law, is that really a good law? If you think so, explain how something that will keep costs the same or increase them while restricting transparency is a good thing.

2. Did the BBC lie? If you disagree, what universe are you in?

3. Did Lingle lie? If you disagree, ditto. Can anyone locate any MSM sources who told you that HI's governor lied about basic, indisputable facts?

4. Can anyone find even one *specific* thing I've gotten wrong or one *specific* misleading or illogical statement in any of my coverage? If, *specify* exactly what you think is wrong. I've repeatedly challenged people to do that, and all I get is ad homs; I don't expect that to change.
