- Empirical constraint(what the statement says should guide science, not politics)
- A limit or boundary set by what we can actually observe and measure in the world—the facts that force us to accept certain conclusions.
- Epistemic values(describing what makes knowledge and theories valuable)
- The qualities we think are important when evaluating whether a belief or theory is good—like preferring ideas that are simple, consistent, or help us discover new things.
- Non-epistemic values(Douglas (2000), p. 565)
- Ethical value judgements that enter into decisions at stages internal to scientific reasoning, such as data collection and interpretation, as distinct from purely cognitive or theory-evaluative criteria.
- Political contingency(what the statement warns science might become hostage to)
- Things that depend on temporary political circumstances or who's in power, rather than on objective facts that would be true no matter what.
- Underdetermination-by-values(the main problem described in the statement)
- When there isn't enough scientific evidence to choose between competing explanations, so our personal values or politics end up deciding which one we believe instead.
- interpretation(Formal semantics for modal nonmonotonic logic)
- A complete, consistent set of literals
- underdetermination(Philosophy of science; here applied (erroneously by some) to Gold's language learnability results)
- The epistemic situation in which a finite body of evidence is insufficient to uniquely determine the correct theory among competing alternatives
