Chapters 5 and 6 Logical Blueprints for Social Policy
June 15, 2026
This episode digs into two chapters from Peter Linquiti’s Rebooting Policy Analysis, exploring the logic and evidence standards that transform a policy argument from passionate opinion into rigorous professional analysis. Drawing on Stephen Jay Gould’s concept of “provisional assent,” the conversation reframes provisional truth not as weakness but as intellectual honesty — and shows why anchoring every claim in a clear counterfactual is what separates credible analysis from advocacy.
The logic toolbox covered includes causal reasoning, reasoning by analogy, abductive reasoning (systematically eliminating competing hypotheses through a matrix of evidence), and reasoning by classification — illustrated through a landmark study showing how categorizing homeless shelter users by usage pattern completely rewrote housing policy design. The episode also names the is-ought trap: the gap between describing a problem and prescribing a solution that moral urgency alone can never bridge.
Finally, listeners learn to weigh evidence by triangulating across stakeholders, gray literature, and peer-reviewed research; to apply four validity tests to any study; and to present findings through a “traceable account” that builds trust with decision-makers without overstating certainty.
