REAL-WORLD INTERPRETIVE

SIMULATION LITERACY

Scenarios Are Not Forecasts

A practical distinction among exploratory scenarios, probabilistic forecasts, observations, and policy decisions.

LEVEL 1

ORIENTATION

Why this matters

REAL-WORLD INTERPRETIVE

One-sentence brief

Confusing these categories can turn a useful thought experiment into false certainty or make a vivid counterfactual look like an official warning.

REAL-WORLD INTERPRETIVE

Three key points

  1. Scenarios are conditional: “if these assumptions hold.”
  2. Forecasts require calibration, probability, horizon, and later evaluation.
  3. Observed facts and policy choices must remain traceable outside the model narrative.
LEVEL 2

WORKING BRIEF

Evidence, context, and limits

REAL-WORLD INTERPRETIVE

Scenario

A scenario is a structured counterfactual. It explores what may follow if stated conditions, relationships, and interventions are assumed. It can expose dependencies and failure modes without claiming that the branch will occur.

  • State the assumptions in the same view as the result.
  • Label branch identity and divergence point.
  • Do not assign probability unless a forecasting method supports it.
REAL-WORLD INTERPRETIVE

Forecast

A forecast estimates what is expected within a defined horizon. It should specify a target, base rate, probability or interval, model version, issue time, and evaluation rule.

  • Evaluate forecasts against later outcomes.
  • Publish calibration and error, not only successful examples.
  • Separate probability from confidence in the evidence.
REAL-WORLD INTERPRETIVE

Observation

An observation is a measurement or source report. It can be incomplete, delayed, biased, or erroneous, but it should not be rewritten merely because a model expected something else.

  • Retain raw-source lineage.
  • Mark revisions and late reports.
  • Do not backfill observations from simulated states.
REAL-WORLD INTERPRETIVE

Decision

A decision is an accountable choice made under evidence, law, values, resources, and risk. A model may inform the decision but should not conceal who chose, which alternatives were considered, or which harms were accepted.

  • Name decision authority and date.
  • Record dissent and rejected alternatives.
  • Allow review and correction.
REAL-WORLD INTERPRETIVE

A simple communication test

Before publication, ask whether a reader could identify what was measured, what was assumed, what was simulated, what was forecast, and what was decided. If those states blur, the presentation needs revision.

  • Use explicit labels.
  • Avoid future-tense certainty for scenarios.
  • Keep explanatory narrative subordinate to state labels.
REAL-WORLD INTERPRETIVE

Correction and supersession

A scenario may remain historically useful after its assumptions change, while a forecast should be scored and a factual record should be corrected. Supersession should preserve the earlier state without presenting it as current.

  • Do not erase failed forecasts.
  • Link corrected data to derivative outputs.
  • Keep archived branches visibly non-current.

Limitations, game links, and review context

DISPUTED / MULTIPLE ACCOUNTS

Known limitations and gaps

  • This is a non-operational educational transformation: it does not build or implement a game, executable simulator, forecasting service, emergency tool, or decision system.
  • This page is an educational transformation of supplied research leads; it does not authenticate every citation, equation, product claim, or institutional attribution in those files.
  • A scenario, model run, or map is not an observation, forecast, legal finding, public-health instruction, emergency warning, or proof of future behavior.
  • No source code, nuclear-effects formula, casualty calculation, target-selection method, cyber-intrusion procedure, exploit chain, or instruction for bypassing safeguards is published.
  • Geography, nationality, ethnicity, religion, language, migration, disability, health, poverty, or political identity are not inherent danger, compliance, intelligence, competence, or worth variables.
  • Specialist scientific, public-health, accessibility, legal, regional, ethics, security, and lived-experience review remains pending; the page stays open to correction.
