Theory 83/Déjà vu/Threshold lens
It Needs a Novelty Threshold
The claim
Déjà vu requires a threshold in scene novelty, appearing where the environment is familiar enough to match but novel enough to require checking.
01Mechanism
The checking process is engaged by novelty; the threshold determines whether the mismatch becomes conscious.
02Prediction
Occurrence should peak at intermediate novelty.
03Refutation
Occurrence tracking familiarity would remove novelty.
