The primary obstacle to objective political truth lies in the field’s reliance on normative claims. Political discourse is driven by questions of should and ought—what should justice look like, how ought resources to be distributed, and which freedoms ought to be protected. These are questions of moral philosophy, where competing core values such as liberty, equality, security, and efficiency are weighed against one another. Since these values often exist in tension (e.g., increasing social equality may require curtailing economic liberty), the "truth" of a policy is entirely dependent on the weight a specific ideological framework assigns to each value, making a truly objective assessment impossible without first agreeing on a universally accepted moral hierarchy, which humanity has demonstrably failed to achieve.
