A speculative novella by Ridley Park
“Behavioural autonomy is a fragile illusion.”
Overview

“Consciousness is the parent of all horrors.“
— Thomas Ligotti
Propensity is a speculative novel about the weaponisation of peace.
Set in a not-quite-now Earth, it traces the creation, deployment, and eventual collapse of a device that alters human behaviour—not actions, but tendencies. No mind control. Just a little nudge to make you less angry. More obedient. Less curious.
It begins clinically. Ends apocalyptically. And in between, it asks: what happens when obedience outlives orders? When peace persists without will? When modulation replaces meaning?
If it sounds like dystopia, it is. But not loudly. Propensity whispers. Flat affect. Surgical precision. Institutional dread.
Themes
- Free will as illusion
- Peace as compliance
- Drift, echo, and the limits of modulation
- Obedience without belief
- Institutional horror and soft dystopia
- Consent, control, and behavioural architecture
- Narrative as residue
- Collapse by calibration
