CARB research chief Bart Croes said Enstrom's fine-particulates health study was not "inconsistent with ones we've used in our work," but he saw "deficiencies" in Enstrom's methodology. Some critics suggest that while his study aligned with other research, and has been cited by the U.S. EPA, his test group was too old; besides, Enstrom is too stingy with caveats and too activist in his interpretations.
Maybe the critics are right. Or maybe that's how they always go after conservatives. It's not simply that they disagree, it's that the scientist in question doesn't meet this hallowed academic standard that is rarely if ever applied to left-leaning scientists/activists. They believe in academic freedom, but that doesn't mean they should have to tolerate dissent.
