Why it belongs here
Understand the loop without reducing the person to it.
Capacity–Uncertainty Regulation Loop (CURL) asks whether some checking, reassurance seeking, rumination, ordering or other repetitive behaviour may sometimes function as an attempt to regain safety, orientation or continuity when capacity is reduced or difficult to trust.
The paper keeps multiple routes open: established OCD processes, pain, sleep disruption, stress, medication effects, sensory load and—in selected cases—neurological, inflammatory, metabolic or other medical contributors. No route is assumed to apply to every person.
This follows naturally from the first two Psy-chology publications. Loss Is Not Nothing examines adaptation when a learned relationship changes. Learning Is a Matter of Perspective examines how different bodies, histories and feedback shape a working model. CURL asks what happens when present capacity or confidence in that model becomes constrained.
How to read the evidence
Supported links.
Unproven model.
The review brings established and emerging findings into one proposed sequence. Research supports relationships among pain and cognition, anxiety and working memory, sleep and emotion, some medication effects, uncertainty in OCD, and repeated checking with reduced memory confidence. Published secondary obsessive-compulsive syndromes show that medical routes can exist.
Those findings do not establish CURL as a validated clinical model, estimate how often a proposed route applies, or prove the cause of one person’s symptoms. Environmental evidence is associative and heterogeneous; individual exposure requires independently verifiable timing, dose, route and comparison data.
Editorial assessment: the paper’s strongest contribution is not a new diagnosis but a falsifiable sequencing question: what capacity is unavailable or mistrusted, what uncertainty follows, what protection does the loop attempt, and what evidence would distinguish the possible causes?
