What do open sources say about habituation and the "cheap scare" failure mode: why do repeated or predictable scares lose force, and what can be checked in a script or cut?

One open psychophysiology study (N = 50, Run Lola Run, a suspense film rather than horror) found self-reported suspense and arousal and skin conductance fell across three viewings while enjoyment did not significantly change, which the authors read as habituation. Horror-specific evidence is indirect: focus-group participants describe learned genre cues, and the jump-scare paper reports scares without anticipatory cues as more startling in an unreviewed experiment. No source measures habituation to repeated jump scares within a single film. Curator qualifications: All numbers and quotes verified. The arousal drop was significant at both steps; the suspense drop was significant only from first to second exposure, as the candidate states. The scope caution (re-viewing habituation, not within-film scare fatigue) is correct. The rights_conflicts entry compares licences of different works (CC BY S1/S4 vs copyright-reserved S3). That is not a conflict between texts and should be removed. Per-source terms stay recorded. The S3 same-work footer-vs-notice conflict is in C3R-0189. The 'unreviewed experiment' status of the jump-scare paper's cue result is the producer's characterisation; it was not re-checked in this pass. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
