Definition

The conjecture–refutation cycle is Popper’s iterative account of scientific inquiry: a problem prompts a tentative theory, criticism and testing eliminate errors, and surviving work produces new problems. RB1 presents it as selective growth of knowledge rather than a route to final certainty. Its cumulative force depends on repeatable methods and institutional transmission, not a theory confronting facts in social isolation.

Explanation

The explicit sequence keeps invention and criticism in different roles. A conjecture offers a possible solution; empirical testing and argument expose failures. A theory that survives is still provisional rather than proven absolutely true. The native Popper references preserve this epistemological attribution instead of treating the cycle as a newly discovered physical mechanism.

Hull’s adjoining account adds publications, teaching, methods and communities that make solutions repeatable. RB1 expressly says replication and selection complete rather than refute the logical skeleton of criticism. This prevents the proposed entry from reducing scientific development either to pure deduction or to popularity alone.

Stengers’s later qualification permits the world to challenge the question itself, not just choose among already fixed answers. AB’s native objectivity note makes the same resistance central. The cycle consequently includes revising problem-frames and methods when inquiry requires it; no guaranteed improvement or final exhaustive account follows from repeated testing.
