One-sentence summary
Change management framework rooted in social neuroscience.
Mechanisms
Psychological
Status, Certainty, Autonomy, Relatedness, Fairness — drivers of social brain response.
Behavioral econ.
Change management framework rooted in social neuroscience.
Neurological
Reward, threat, and salience circuits bias attention toward the cue.
Evolutionary
Heuristics that paid off in ancestral environments now misfire in modern systems.
Sociological
Group norms and status incentives reinforce the pattern across a team.
Computational
Models trained on biased human signals will replicate and amplify the pattern.
Systems thinking
Feedback loops between metrics, incentives, and behavior lock the pattern in place.
Signals & signature
Inputs (activators)
Reorgs that violate certainty AND autonomy AND fairness at once.
Outputs (observable)
Change management framework rooted in social neuroscience.
Behavioral signature
You see SCARF Model (Rock) when the explanation for a decision sounds reasonable but the outcome keeps repeating.
Behavioral molecules
Often combines with related Atlas entries — see the rail below.
Pathways · before
A goal, metric, or contract clause makes the behavior rational locally.
Pathways · after
Locally rational choices accumulate into a systemic distortion.

The Perverse Incentive Lens™
How it's exploited
Organizations weaponize scarf model (rock) — sometimes deliberately, often by accident — when metrics reward the symptom rather than the outcome.
Common perverse incentives
Volume metrics, short review windows, bonus cliffs, and contracts that pay on activity rather than impact.
Failure modes
When SCARF Model (Rock) dominates, teams optimize for the dashboard while the real outcome quietly degrades.
Incentive redesign
Audit major moves against SCARF. Mitigate the worst breaches.
Ethical considerations
Don't engineer scarf model (rock) into customers, employees, or citizens as a manipulation tactic — design for informed choice instead.
Diagnostic questions
  • Where in our org would SCARF Model (Rock) most often show up unnoticed?
  • Which metric, ritual, or contract clause quietly rewards SCARF Model (Rock)?
  • If we removed every payoff for SCARF Model (Rock), what behavior would replace it?
  • Who benefits when SCARF Model (Rock) persists — and who pays the cost?
Organizational warning signs
Metrics
A KPI is hit while the underlying outcome stalls or worsens.
Behaviors
People route around the rule rather than challenge it.
Language
'That's just how we do it here.' / 'The system requires it.'
Culture
Naming the pattern is treated as disloyalty.
Red flags
  • People defend the status quo using the language of scarf model (rock).
  • Decisions cluster around the easiest narrative rather than the strongest evidence.
  • New data changes the slide deck but not the decision.
  • Anyone naming the pattern is treated as the problem.
Intervention playbook
Immediate
Make the perverse payoff visible to the people creating it.
30-day
Run a small pilot that pays for the outcome, not the proxy.
Long-term
Rewrite the comp plan, contract, or ritual so the right behavior becomes the easy behavior.
AI considerations
Detect
Audit training data and reward signals for the same pattern this element describes.
Avoid amplifying
Don't optimize models on metrics that already encode the perverse incentive.
Counteract
Use the model to surface where the pattern is most active, then redesign the incentive — not the model.
Measurement
Metrics
Outcome-to-proxy ratio over time.
Assessment
The Incentives Lab III Diagnostic.
Survey
Calibrated pulse questions on rules vs. outcomes.
Behavioral signals
Where people work around the system.
Observational
Where the dashboard and the lived experience disagree.
Scientific evidence
Evidence grade
Synthesized from the behavioral science literature; see Atlas references.
Replication
Tracked in the Atlas as primary, replicated, or contested.
Intervention confidence
Moderate — patterns generalize, mechanisms vary by context.
Research consensus
Broad agreement on the pattern; ongoing debate on boundary conditions.
Known limitations
Local context, culture, and incentive structure all change the strength of the effect.
Open questions
How does SCARF Model (Rock) interact with AI-mediated decisions at scale?

How this lands in you

Your nervous system has a region for this.

Primary region
Default Mode Network

When you encounter SCARF Model (Rock), your default mode network folds the experience into your ongoing story-of-self — which is why the same fact lands differently depending on who you think you are.

Self-referential thought, mind-wandering, narrative-of-self, mental time travel. Most of your waking thought is this network running scenarios about you, your status, your past, and your future.
