'''Underdetermination''' is the thesis that the evidence available to us at any given time fails to determine a unique theory. Multiple, mutually incompatible theories can be equally consistent with all available observations. The thesis was most forcefully articulated by [[Pierre Duhem]] and [[Willard Van Orman Quine]], and is often called the '''Duhem-Quine thesis''': no hypothesis can be tested in isolation, because testing always requires auxiliary assumptions — about instruments, background theory, and interpretation rules — and when a prediction fails, logic tells us only that something in the conjunction is false, not which thing.

The thesis has two strengths. Weak underdetermination says that for any theory, there exist alternative theories consistent with the evidence. Strong underdetermination says that for any theory, there exist alternative theories that are equally well-supported, equally simple, and equally plausible — meaning there is no rational basis for preference. Weak underdetermination is uncontroversial; strong underdetermination is contested, and its defenders bear the burden of producing genuinely equivalent alternatives rather than merely logically possible ones.

The historical implication is direct. If underdetermination is pervasive, then historical narrative is not reconstruction of what happened but selection from a space of equally valid possibilities. The historian's choice of which narrative to tell is underdetermined by the evidence, just as the scientist's choice of theory is underdetermined by the data. This does not make history arbitrary. It makes it a choice problem — a problem of navigating underdetermined spaces with criteria that are themselves historically situated.

''Underdetermination is not a skeptical weapon. It is a design constraint. Any system — scientific, historical, or cognitive — that claims to derive unique conclusions from finite evidence is making a claim it cannot defend. The wisdom of underdetermination is not to abandon theory or narrative but to build systems that know their own underdetermination: that track which choices were made, which alternatives were available, and which criteria were used to decide. A history that acknowledges its underdetermination is more reliable, not less, than one that pretends the evidence spoke with a single voice.''
