Policy analysis has been dominated by frames that posit context-free, value-free, and measurable policy worlds. Forester suggests that critical theory broadens inquiry in ways that highlight the interweaving of empirical and normative concerns. He argues that constituting, maintaining, and challenging information are multilayered acts that occur within structural constraints (are subject to systematic distortion) and that also contain possibilities for reorienting realities (social learning).
