Less is more: on how reasoning increases epistemic status

Abstract This paper challenges the widely accepted view in contemporary epistemology that deductive reasoning is merely epistemically preservative – that it only transmits epistemic status from premises to conclusion without enhancing it. While this strong preservationist view has been central to both internalist and externalist theories, we argue that deduction can play a more dynamic and productive epistemic role. We defend the thesis that valid deductive inference is a rational tool for managing epistemic risk. Specifically, when an agent reasons from a more informative premise to a less informative conclusion, the resulting belief can achieve an enhanced epistemic status in key dimensions such as modal safety and resilience to defeat. Our novel contribution is to identify the mechanism for this enhancement: a deliberate trade-off between a proposition’s semantic informativeness and its epistemic security. Unlike other anti-preservationist accounts that focus on the generation of justification ex nihilo , our account explains the amplification of a pre-existing epistemic status. We argue that while this inferential move entails a loss of information, the value of the resulting epistemic gain is context-dependent, proving crucial in high-stakes reasoning where error avoidance is paramount. By recognizing that deductive reasoning can enhance – not just preserve – epistemic status, we aim to revise traditional assumptions and contribute to a more accurate and dynamic understanding of reasoning in our epistemic lives.
