Evidence map: Chemistry of Possibility

A claim-level map separating molecules, circuits, prediction error, wanting and the addiction-cycle framework.

TWO DIMENSIONS, NOT ONE LADDER

Evidence strength and claim origin stay separate.

A strength badge describes the evidence base. An origin tag appears only when a claim is a cross-domain application, an original synthesis or lived-experience knowledge. Visible text—not colour—carries the meaning.

Established

Strong, consistent evidence, high-quality guidance or broad scientific consensus supports this claim.

Supported

Good evidence supports the claim, but important qualifications or limits remain.

Emerging

Promising evidence exists, but replication, larger samples or broader validation is still needed.

ONE COMPLETE TRACE

From the sentence on the site to its inference boundary.

01 · CLAIM

The categories overlap, and neither word gives a molecule one fixed psychological meaning.

02 · SOURCE

Marder, E. · 2012Neuromodulation of neuronal circuits: Back to the future

03 · WHAT IT SUPPORTS

Neuromodulators can reconfigure circuit output in receptor-, circuit- and state-dependent ways.

04 · BOUNDARY

The claim rejects one-molecule slogans; it does not deny biological effects or replace medicine-specific evidence.

CLAIM MAP

Claim → source → use → boundary.

This is why learning, wanting, liking and movement cannot be collapsed into a single global dopamine level.

WHAT THIS SOURCE SUPPORTS

Some dopamine responses encode components of reward-prediction error under defined tasks and conditions.

WHAT IT DOES NOT ESTABLISH

A global dopamine score, pleasure meter, diagnosis or personal treatment selector.

WHAT THIS SOURCE SUPPORTS

Incentive wanting and hedonic liking can separate in addiction-related processes.

WHAT IT DOES NOT ESTABLISH

That dopamine alone explains addiction or that wanting is identical across people and substances.

Lecture 46 · Section 2 · Part II · Dopamine and the force of the future

Wanting can become powerful without pleasure, endorsement or freedom.

WHAT THIS SOURCE SUPPORTS

Sensitized incentive salience can make cues strongly wanted even when liking or explicit endorsement is weak.

WHAT IT DOES NOT ESTABLISH

Loss of all agency, inevitability of use or a universal account of addiction.

WHAT THIS SOURCE SUPPORTS

Addiction involves interacting reward, stress and executive-control circuits across binge, withdrawal and preoccupation stages.

WHAT IT DOES NOT ESTABLISH

One identical circuit profile for every person or that neurocircuitry is the whole person and social field.

REFERENCE INTELLIGENCE MAP

What each researcher contributed—and where Flow Hijacked goes beyond it.

Attribution does not imply endorsement of the project. It shows intellectual dependence and its limits.

#claim-molecule-context

Eve Marder

WHAT THIS SOURCE OR PERSON ACTUALLY ARGUES HERE: Showed that neuromodulatory effects depend on circuit configuration and state.
DIRECTNESS: Direct mechanistic framing from circuit neuroscience.
DISAGREEMENT OR LIMIT: The review is not a clinical theory of addiction or depression.
FLOW HIJACKED EXTENSION: Flow Hijacked translates state-dependent modulation into a wider account of reachable action.

#claim-dopamine-components

Wolfram Schultz

WHAT THIS SOURCE OR PERSON ACTUALLY ARGUES HERE: Specified component reward-prediction-error signalling rather than a global pleasure signal.
DIRECTNESS: Direct for defined learning signals; indirect for a whole life or diagnosis.
DISAGREEMENT OR LIMIT: The work does not endorse popular dopamine-detox or dopamine-level narratives.
FLOW HIJACKED EXTENSION: The lecture places prediction error beside effort, action, wanting, context and other modulators.

#claim-dopamine-components · #claim-wanting-without-liking

Terry E. Robinson & Kent C. Berridge

WHAT THIS SOURCE OR PERSON ACTUALLY ARGUES HERE: Distinguished incentive wanting from hedonic liking.
DIRECTNESS: Mechanistic and theoretical support across addiction research.
DISAGREEMENT OR LIMIT: Their theory is influential but not a complete or uncontested account of every addiction.
FLOW HIJACKED EXTENSION: Flow Hijacked connects the distinction to agency, effort and the reachability of ordinary reward.

#claim-coupled-state

George F. Koob & Nora D. Volkow

WHAT THIS SOURCE OR PERSON ACTUALLY ARGUES HERE: Organized addiction across reward, stress and control stages and circuits.
DIRECTNESS: Review-level neurocircuitry support.
DISAGREEMENT OR LIMIT: The framework does not reduce recovery to circuitry or specify one route for every person.
FLOW HIJACKED EXTENSION: The lecture adds body, relationship, meaning and time to the neurocircuitry arc.
