Law of Triviality + Goodhart Combined

When trivial metrics become the target, the trivial becomes the strategy.

"We measured what was easy. So we did what was easy."

Quick answer

What is Law of Triviality + Goodhart Combined? When trivial metrics become the target, the trivial becomes the strategy. Operating system slowly optimized for ease of measurement, not value.

In the wild

Engagement metrics tracked because they were measurable; outcomes ignored because they weren't.

Why it matters in the room

Operating system slowly optimized for ease of measurement, not value.

AI implication

AI evaluation built on the metrics that were already in the dashboard.

Counter-move

Build the metric for the outcome, not the outcome for the metric.

Law of Triviality + Goodhart Combined
Definition
Scientific
When trivial metrics become the target, the trivial becomes the strategy.
Plain-English
When trivial metrics become the target, the trivial becomes the strategy.
Feynman
We measured what was easy. So we did what was easy.
Core principle
When trivial metrics become the target, the trivial becomes the strategy.
One-sentence summary
Operating system slowly optimized for ease of measurement, not value.
Mechanisms
Psychological
When trivial metrics become the target, the trivial becomes the strategy.
Behavioral econ.
Operating system slowly optimized for ease of measurement, not value.
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
AI evaluation built on the metrics that were already in the dashboard.
Systems thinking
Feedback loops between metrics, incentives, and behavior lock the pattern in place.
Signals & signature
Inputs (activators)
Engagement metrics tracked because they were measurable; outcomes ignored because they weren't.
Outputs (observable)
Operating system slowly optimized for ease of measurement, not value.
Behavioral signature
You see Law of Triviality + Goodhart Combined 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.

Operating system slowly optimized for ease of measurement, not value.
How to reduce
Build the metric for the outcome, not the outcome for the metric.
How to redesign
Build the metric for the outcome, not the outcome for the metric.
The Perverse Incentive Lens™
How it's exploited
Organizations weaponize law of triviality + goodhart combined — 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 Law of Triviality + Goodhart Combined dominates, teams optimize for the dashboard while the real outcome quietly degrades.
Incentive redesign
Build the metric for the outcome, not the outcome for the metric.
Ethical considerations
Don't engineer law of triviality + goodhart combined into customers, employees, or citizens as a manipulation tactic — design for informed choice instead.
Diagnostic questions
  • Where in our org would Law of Triviality + Goodhart Combined most often show up unnoticed?
  • Which metric, ritual, or contract clause quietly rewards Law of Triviality + Goodhart Combined?
  • If we removed every payoff for Law of Triviality + Goodhart Combined, what behavior would replace it?
  • Who benefits when Law of Triviality + Goodhart Combined 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 law of triviality + goodhart combined.
  • 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
AI evaluation built on the metrics that were already in the dashboard.
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.

How this lands in you

Your nervous system has a region for this.

Primary region
Prefrontal Cortex

When you encounter Law of Triviality + Goodhart Combined, your prefrontal cortex has to do extra work to override the automatic response — and that override budget is finite.

Executive control, planning, impulse override, working memory, System 2. First thing to go offline under stress, fatigue, or low blood sugar. Why your 4pm decisions are worse than your 9am ones.
