Criticism

Criticism is the process of actively attempting to expose errors in a conjecture.

A conjecture is open to criticism if some process could, in principle, reveal an error in it. Criticism is the execution of that process.

Properties

Criticism:

• is directed at explanations, not persons
• consists of attempts to determine whether an explanation survives contact with reality
• requires that the conjecture be open to refutation

Criticism does NOT:

• require disagreement or hostility
• require a replacement explanation
• guarantee that errors will be found

The mechanism of criticism is deductive: consequences are derived from the conjecture and compared against observation.

A conjecture that avoids criticism does not become safer. It becomes epistemically inert.

Distinctions

Disagreement is a difference of position. It may be stated without identifying an error.

Skepticism is doubt about a claim. It may persist without offering any test.

Rejection is refusal to accept a claim. It may occur without examination.

Criticism is distinct from all three. A person may agree with a conjecture and still subject it to criticism. A person may doubt a conjecture without ever testing it.

Error Correction

Criticism exposes errors. Error correction removes them.

When criticism identifies a failure, the explanation is revised, restricted, or abandoned. What survives is retained by critical preference, not by confirmation.

Criticism without error correction is sterile: it identifies problems without improving knowledge. Error correction without criticism is impossible: there is no independent access to truth that would allow direct correction.

Example

Building on the knowledge example:

Conjecture: They are not calling because they have decided not to pursue the relationship further.

Criticism: You learn the person was hospitalized during the period of silence.

This tests the explanation against a new fact. The explanation predicted that silence reflected a decision. The hospitalization offers an alternative cause.

If the hospitalization fully accounts for the silence, the original explanation fails and is revised or abandoned. If the hospitalization was brief and silence continued, the original explanation survives this criticism.

In either case, the conjecture has been subjected to a process that could expose an error. That is what makes it criticism.
