Addiction

Finding
Addiction is compulsive use despite adverse consequences. The mesolimbic dopamine pathway is central: addictive substances produce dopamine release exceeding the natural range. With repeated exposure, the system adapts — receptor downregulation and baseline dopamine decline. Tolerance (same dose, less effect) and dependence (absence produces deficit) result. Koob’s opponent-process model describes a shift from positive reinforcement (seeking pleasure) to negative reinforcement (avoiding withdrawal). The system oscillates between excess and deprivation.
Properties Violated
Proportion violated in both directions — the substance produces disproportionate reward (exceeding natural stimuli), and tolerance then produces disproportionate deficit. The system oscillates, never returning to proportional response.
Alignment inverted at the organism level — the addicted person’s stated purpose (stop, control) and actual action (continue, escalate) diverge. But the addiction has its own alignment: molecule to receptor is perfectly consistent. Addiction is alignment at the wrong level — the molecular mechanism aligned with the receptor, the organism misaligned with its own survival.
Humility violated — the substance claims authority over the entire reward system, overriding other sources of meaning.
Connections
- Addiction Revisited — the structural paradox explored further: alignment at the wrong level
- Feedback Control — addiction is a hijacked feedback loop (→ Meta-Pattern 09)
- Chemical Signaling — addiction overwhelms proportional chemical signaling
- Cancer — both are instruments (cells, reward system) claiming authority of the whole organism
- Far-From-Equilibrium — addiction pushes the reward system out of its proportional range
Status
Established neuroscience. Volkow et al. (2017). Koob’s model widely cited. NIDA definition standard (contested by Hart, 2021). Structural analysis is this project’s interpretation.
The mapping to the five properties is this project’s structural interpretation.
