A new book by conservative spinmeisters purports to correct the mainstream media's liberal spin on science news. It Ain't Necessarily So: How Media Make and Unmake the Scientific Picture of Reality [2], by authors David Murray, Joel Schwartz and S. Robert Lichter, argues that the mainstream media's science coverage is slanted by a liberal agenda. But the authors--scholars at the Hudson Institute and other conservative institutions--have an agenda of their own: debunking global warming, extinction reports, and other issues that paint an unflattering picture of their corporate sponsors.
