CRITICAL THEORY AND PUBLIC POLICY

In the confines of the study of politics, public policy analysis involves a shift from pure to applied research, a shift which intensifies the problem of the fact-value split inherited from positivist behavioralism. While early public policy literature concentrated on empirical policy-making processes bypassing moral criteria, some recent writings have elaborated on policymaking and policy evaluation as a type of normative inquiry; significant steps in this direction have been undertaken by Duncan MacRae and especially by Jurgen Habermas in the context of “critical theory.” According to Habermas, policy evaluation requires a critically reflective “practical discourse” open not only to experts or policy analysts but to the public at large. The paper argues that such discourse is a valuable remedy against the technical-instrumental bent of applied science, but that recovery of a fully non-instrumental “practical” judgement presupposes an evaluation not only of concrete policies but of the status of “policy” itself.     

Assessing Collector Bias: A Geometric Morphometric Analysis of a Collection of Isolated Clovis Points from the Midcontinent

Clovis points are found across the contiguous United States as isolated surface finds and as elements of assemblages in surface and subsurface deposits. Despite being scattered over the continent, Clovis points exhibit a remarkable degree of standardization, yet there is still a demonstrable level of variation in their shapes across regions. Including isolated points in regional comparative analyses would significantly increase sample sizes and spatial coverage of these analyses; however, the effects of collector bias—the tendency to collect the most typical and aesthetically pleasing points—are unknown. Here, we examine the shape of a sample of isolated Clovis points from the midcontinent using geometric morphometric techniques. We show that resharpening had little effect on the shape of points and that our sample of isolated points are similar in shape to points from assemblages in the midcontinent. Our findings suggest that isolated points have research potential when collector bias is limited.
