Systems Thinking

Feedback loops, stocks, flows, delays, and leverage points. Where structural change actually lives.

What feedback loop is reinforcing this behavior?

How this layer reinforces, counteracts, or depends on the rest of the system.

  • Reinforces·Layer
    Game Theory reinforces this layer

    Strategic equilibria become feedback loops once you let the game iterate; both predict structural lock-in.

  • Generalizes·Layer
    This layer generalizes Complexity Science

    Complexity is what systems thinking becomes once agents adapt to each other in real time.

  • Explains·Layer
    Information Theory explains this layer

    Feedback loops are signal channels; noise and delay determine whether the loop stabilizes or oscillates.

  • Depends on·Layer
    Universal Diagnostic Questions depends on this layer

    The 20 questions only produce insight if you can trace second- and third-order effects through the system.

  • Explains·HBE
    This layer explains Goodhart's Law

    Goodhart is what happens when a feedback loop optimizes a proxy rather than the underlying stock.

Elements in this layer

55 HBEs
BIOAmygdala Hijack

Emotional override of rational processing.

SYSAntifragility

Systems that gain from disorder.

COGBalancing Loop

Negative feedback returns a system toward a target.

SYSBehavioral Activation System (BAS)

Approach motivation — pursuit of rewards and goals.

SYSBehavioral Inhibition System (BIS)

Avoidance motivation — sensitivity to punishment, uncertainty, and threat.

INCBLM Wild Horse Holding Loop

Expensive off-range storage cannibalizes funds needed for on-range management.

INCBureau of Indian Affairs Trust Delays

Federal oversight intended to protect tribal assets creates friction that devalues the land.

SYSCausal Loop Diagram

Map reinforcing (R) and balancing (B) feedback loops between variables to see system behavior.

SYSComplex Adaptive System

A system with many interacting parts that learn and adapt.

SYSComplex Adaptive Systems

Many interacting parts producing emergent behavior nobody designed.

INCConcept Drift

The relationship between inputs and outputs changes.

INCData Drift

Underlying data distribution changes over time.

SYSDouble-Loop Learning

Single-loop fixes the action. Double-loop questions the goal or model that produced it.

SYSDual-System Theory

System 1 is fast, automatic, intuitive; System 2 is slow, effortful, deliberate.

COGEconomic Bubble

Prices driven far above intrinsic value by feedback loops of belief and behavior.

SYSEcosystem

Interdependent network of actors evolving together.

SYSEmergence

The whole has properties that the individual parts do not.

IDNEmpathy Gap

Cold-state decisions don't survive hot-state moments.

SYSEquilibrium / Homeostasis

Systems maintain stability by self-regulating around a setpoint.

SYSEquilibrium Behavior (Experimental)

Subjects often converge to neoclassical predictions only after many rounds of feedback — not on the first try.

COGEscalation of Commitment

Continuing a failing course of action because of prior investment.

INCEval Drift

Evaluation suites that no longer reflect real-world conditions.

SYSExternalities

Costs or benefits that affect third parties not involved in a transaction.

COGFeedback Loop

Output of a process re-enters as input.

SYSFeedback Loops

Outputs of a system are routed back as inputs, amplifying or dampening change.

COGFlywheel Effect

Self-reinforcing loops of momentum.

SYSGlymphatic System

The brain's overnight cleaning system; clears metabolic waste during sleep.

INCHyper-Specialization Drift

Deep specialization improves local output but breaks cross-domain understanding.

COGIncentive Drift

Reward systems slowly diverge from the outcomes they were meant to drive.

SYSInformation Cascade

People copy the choices of others, assuming they have private information.

INCInsurance Claim Friction

Insurers profit when claims are denied, delayed, or abandoned.

INCLatency Budget

How much delay the user experience tolerates.

SYSLearn-Do-Teach Loop

Three-stage cycle: learn by seeing, learn by doing, learn by teaching — looped continuously.

COGLearning Network

A deliberately curated set of people, sources, and feedback loops you draw on to learn faster than alone.

COGMarshmallow Effect

Children who delay gratification at age 4 show better outcomes across nearly every metric decades later.

INCModel Drift

Performance degradation as real-world data shifts.

SYSNash Equilibrium

A state where no player benefits from changing strategy unilaterally.

SYSNetwork Effects

Value grows with the number of users.

INCNo-Feedback Loops

Systems with weak corrective feedback drift unchecked into failure modes.

SYSOODA Loop

Observe, Orient, Decide, Act — faster than your competitor.

INCPrior-Authorization Rules

Insurer approval workflows delay or deny care to lower medical-loss ratios.

SYSQuantal Response Equilibrium

A behavioral relaxation of Nash: players choose better strategies more often, but not always — errors are smooth, not binary.

COGReinforcing Loop

Output amplifies input — virtuous or vicious cycle.

INCReporting Incentive Drift

When budgets follow self-reported numbers, the numbers drift toward what funders want to see.

SYSSingle Loop vs. Double Loop Learning

Single-loop fixes errors; double-loop questions the assumptions producing them.

SYSSingle-Loop vs Double-Loop Learning (Argyris)

Single-loop: fix the action. Double-loop: question the governing assumption behind it. Chris Argyris.

INCStack-Rank Calibration Drift

Manager calibration produces predictable distortions over years.

SYSStock and Flow

Stocks are accumulations; flows are rates of change that affect them.

SYSSystems Thinking

Behavior emerges from structure, not from individuals.

COGTragedy of the Commons

Shared resources get over-consumed by individual rational actors.

SYSTwo Loops Model

Old systems decline as new ones emerge in parallel; leaders steward both, not just kill the old or chase the new.

SYSEnvironment

The context that shapes behavior

SYSDyadic Dynamics

Patterns between two people

SYSMarket Structure

Rules shape competition

SYSInstitutions

Laws, systems, and governance
