Happy Birthday to Jo Ann Pflug, 73.
To the good stuff:
1. Aaron Carroll and Austin Frakt go in depth on yesterday's Oregon Medicaid study. I screwed this up in the Roundup at Greg's place last night, and I shouldn't have. The initial spin was that the study showed no health benefits (while also showing substantial financial benefits) from Medicaid, but that's an incorrect reading. It does show some benefits, but mainly the evidence is inconclusive -- and it's not clear, Carroll and Frakt explain, that the study was able to actually reach conclusions on health outcomes. And at any rate, what evidence there is points in the right direction (that is, in the direction of Medicaid helping people stay healthy), but is not statistically significant -- which is hardly the same thing as a claim of "no effect." Anyway, if you want to know more, click through; Carroll and Frakt walk everyone through it.
(I don't, and can't, read every study for which I link to a blog post or news article which summarizes it. But I need to do better than I did on this one).
2. Dan Drezner, still a pessimist about political science and Congress.
3. And speaking of that first one: advice from Betsey Stevenson and Justin Wolfers, for non-experts, on how to know what to make of quantitative research.
