Why Not Viewpoint Diversity?

Social psychologist Clay Routledge guest blogging in Scientific American. The tendency that Routledge points to is tone deaf to perfectly legitimate epistemic possibilities (meaningful viewpoint diversity) but we have long since pathologized ideology in a sad grab for power and influence (I have a chapter on this topic coming shortly). Surely the Overton window must be wide open affording the best opportunity to approach truth — but then again, many academics are typically in the business of activism, not inquiry.
