AIM Framework glossary
True Belief
Canonical definition
A True Belief is a Belief that is sincerely held and that corresponds to the state of affairs it concerns. It is the exact complement of Confabulation on the Truth axis: a Confabulation is sincere and wrong, a True Belief is sincere and right, and between them they exhaust an Individual's sincere Beliefs about any matter physical reality has resolved. Where the Decoherence Time of a domain has not yet expired, a Belief about that domain occupies neither classification but the superposed state between them (the Predictive Superposition Principle). A True Belief is not identified by the confidence with which it is held, since certainty and Truth are orthogonal (Certainty-Truth Independence), nor does holding one confer any advantage inside coupled dynamics (Truth-Value Orthogonality). A True Belief is arrived at through Bayesian Belief updating, which is content-agnostic, so what decides whether an Individual arrives at a True Belief or a Confabulation is the Evidence that reaches them.
Explanation
A True Belief is one you hold that is right. Its opposite is a Confabulation, which is one you hold that is wrong. Nothing else separates them. The Bayesian operation that produced the Belief is the same in both cases, the confidence can be identical in both cases, and you have no introspective access to which one you are holding. That is why the AIM Framework never treats the feeling of certainty as evidence of correctness, and why finding out which of the two you hold means going outside yourself: to what physical reality does, or to what other people can see that you cannot.
