Interactive model

Explore before calculating

A layered claim graph connecting a reference study to sources, assumptions, forecasts, measurements, and confidence levels.
A research document becomes teachable when every claim can be followed backward to evidence and forward to a decisive test.

Live research workspace

DIRD claim graph

Select a claim to inspect what anchors it, what challenges it, and which observation would materially change its status.

The quantum vacuum has measurable structure

established

Ground-state quantum fields contribute observable response and fluctuation phenomena even when no ordinary particles are present.

What is established

Lamb shifts, spontaneous emission, vacuum polarization, and boundary-dependent forces are quantitatively described by quantum field theory.

What remains

Those observations do not select one philosophical vacuum picture or prove that the ground state is an extractable work reservoir.

Deciding evidence: No single new test is needed for quantum-vacuum structure; proposed engineering consequences each require their own complete-cycle measurement.

Lesson 1 of 3

Provenance, purpose, and document anatomy

What was the document commissioned to do, and what was it not designed to establish?

A reference study may survey possibilities, assess strategic relevance, or identify research gaps. Its existence, sponsor, classification history, or expert authorship does not convert every discussed proposition into a confirmed result.

Critical reading begins with date, version, authorship, commissioning question, intended audience, methods, cited time horizon, and the distinction between reported evidence and scenario analysis.

provenancescopecommissionforecastscenario analysis

Worked example

A study says a technology could be transformative if three breakthroughs occur. How should that sentence be encoded?

  1. 1. Mark it as conditional.
  2. 2. Extract the three dependencies.
  3. 3. Separate impact forecast from probability.
  4. 4. Record the study date and forecast horizon.

It is a conditional scenario, not evidence that the technology or prerequisites existed.

Document anatomy ledger

Materials: One DIRD and metadata sheet

  1. 1. Record provenance and purpose.
  2. 2. Map section types.
  3. 3. Tag claims as report, synthesis, inference, or forecast.
  4. 4. List explicit exclusions and unknowns.

Notice: Documents often change epistemic mode across sections; one global label loses that structure.

Check your understanding: Does government commissioning establish that a discussed mechanism is true?

Answer: No.

It establishes institutional interest in assessment, not experimental confirmation of every claim.

Lesson 2 of 3

Claim graphs, citation chains, and equation reconstruction

Where does each quantitative statement originate, and does the cited source support the same proposition?

Citation laundering occurs when reviews cite one another until a conditional or disputed statement appears settled. A claim graph records the exact proposition, source location, evidence type, and transformations between documents.

Equations require unit, assumption, boundary, and limiting-case checks. Reproducing one central result often reveals whether a claim is a derivation, parameter choice, analogy, or unsupported extrapolation.

claim graphprimary sourcecitation launderingassumptionreproduction

Worked example

Three reviews cite one another for the same efficiency value but none reports data. What is the evidence status?

  1. 1. Trace the oldest citation.
  2. 2. Search for primary apparatus or calculation.
  3. 3. Record that the value is repeated but unsupported.
  4. 4. Do not count repeated reviews as independent evidence.

The citation network has recurrence, not independent empirical confirmation.

Try it

Five-claim graph

Materials: DIRD, references, and graph template

  1. 1. Extract five central claims verbatim.
  2. 2. Trace each to the earliest accessible source.
  3. 3. Label edge type and confidence.
  4. 4. Reproduce one numerical result.

Notice: The strongest-looking claim may rest on the weakest or most transformed citation chain.

Check your understanding: When do two papers count as independent support?

Answer: When their evidence or derivations are genuinely independent rather than reusing the same source, apparatus, or dataset.

Bibliographic plurality alone is insufficient.

Lesson 3 of 3

Forecast scoring, red teams, and dossier publication

Which expectations survived time, and what would a fair critic and advocate each say now?

Forecasts must be frozen in their original wording and scored against dated outcomes using predeclared categories. Vague relevance claims should not be upgraded into successful quantitative predictions.

A red team identifies hidden assumptions, conventional explanations, and missing controls. A steelman reconstructs the strongest version of the program. The final dossier preserves both and names the evidence that would move confidence.

forecast calibrationhindsight biasred teamsteelmandecision threshold

Worked example

How should a 2010 forecast of a laboratory demonstrator within ten years be scored in 2026 if only simulations exist?

  1. 1. Freeze the original milestone definition.
  2. 2. Search for a physical demonstrator by the deadline.
  3. 3. Do not substitute simulations unless allowed originally.
  4. 4. Score unmet and document partial progress separately.

The demonstrator forecast is unmet; simulation progress is a separate outcome.

Adversarial dossier review

Materials: Draft dossier and two reviewer roles

  1. 1. Assign advocate and critic.
  2. 2. Require source-located objections.
  3. 3. Resolve factual disagreements.
  4. 4. Publish remaining judgment differences explicitly.

Notice: Adversarial review improves a dossier when disagreements are made inspectable rather than averaged away.

Check your understanding: What makes a forecast score reproducible?

Answer: Frozen wording, dated evidence, explicit categories, and a documented scoring rule.

Otherwise hindsight can redefine success.

Formula-to-meaning deck

Read the equation in ordinary language.

P(claim|evidence)∝P(evidence|claim)P(claim)

Evidence updates a claim in proportion to how differently competing explanations predict it.

Brier=(1/N)Σ(p_i−o_i)²

The Brier score measures probabilistic forecast calibration against binary outcomes.

w_source=w_primary·w_independence·w_method

A transparent heuristic weight can record provenance, independence, and methodological strength without pretending to be a universal truth score.

Independent practice

Problem set

Work each problem before opening its hint and solution.

  1. 1. Two papers reuse one experiment. How many independent empirical datasets support the claim?

    Reveal hint

    Count evidence sources, not publications.

    Reveal solution

    One.

  2. 2. A forecast assigned p=0.8 fails. What is its single-item Brier score?

    Reveal hint

    Use (p−o)² with o=0.

    Reveal solution

    0.64.

  3. 3. Why must an equation reproduction retain the source's boundary conditions?

    Reveal hint

    Consider whether the solution is unique or applicable without them.

    Reveal solution

    Boundary conditions select the physical solution and can control the result's magnitude or even sign.

Derivation studio

Build the result, line by line.

Keep the assumptions visible so the mathematics remains auditable.

Starting point

Bayes-factor evidence update

Posterior odds = prior odds × likelihood ratio

  1. 1. Write odds for claim versus alternative.
  2. 2. Compute likelihood of the observation under each.
  3. 3. Form their ratio.
  4. 4. Multiply without changing the frozen prior after seeing the data.

O_post=O_prior·P(E|H₁)/P(E|H₀)

Evidence matters through discrimination, not drama or institutional prestige.

Starting point

Forecast calibration decomposition

Mean squared probability error over binned forecasts

  1. 1. Group forecasts by stated probability.
  2. 2. Compute observed frequency per bin.
  3. 3. Separate calibration from resolution and base-rate uncertainty.
  4. 4. Inspect sample-size limits.

Brier performance reflects calibration, resolution, and outcome uncertainty

A forecast program should be judged across many frozen predictions, not one celebrated hit.

Reference-study critical dossier

What would remain credible if the sponsor, author reputation, and later retellings were removed?

  1. 1. Reconstruct purpose and provenance.
  2. 2. Trace claims to primary evidence.
  3. 3. Reproduce the central quantitative step.
  4. 4. Score forecasts and unresolved assumptions.

Calculation to reproduce: Reproduce the study's most decision-relevant estimate with a sensitivity analysis.

Evidence boundary: A DIRD can be valuable strategic scholarship while containing established, contested, speculative, and outdated claims that must be graded individually.

Graduate oral defense

Defend a bounded claim under pressure.

Argue the strongest support, state the strongest objection fairly, and identify evidence that could actually decide the issue.

Proposition

DIRDs should be taught as auditable research maps, not dismissed as fantasy or treated as revealed truth.

  1. 1. They assemble uncommon technical literature and strategic questions.
  2. 2. Their conditional forecasts and source networks can generate testable programs.
  3. 3. Claim-level grading preserves value without laundering uncertainty.

Strongest objection: Commissioning context and selective topic framing may amplify low-quality or strategically motivated speculation.

Deciding evidence: Independent reproduction of central calculations and prospective success of preregistered discriminating predictions derived from the documents.
