Lately I've been wondering how groups of people on different sides of issues can come to such dramatically different conclusions about the direction of public policy. In many cases, those differences appear to be grounded in honest disagreements. That's how I see the abortion issue, for example, where personal beliefs dominate the political landscape like so many hair-trigger land mines.
In other areas, the differences seem more rooted in deep philosophical divisions where honesty gets caught in the cross fire. That's what's happening in the continuing debate about global climate change, where free-market fundamentalists looking for free-market solutions are cooking the scientific books in pursuit of an ideological agenda. We need look no farther than the Journal of the John Locke Puppetshow to see the phenomenon in action. Today's edition features an ad for another seedy little free-market tank called the Heartland Institute.
