Evidence reasoning

Deterministic verification where possible. Probabilistic judgment where reality requires it.

Aperture separates what can be tested directly from what can only be assessed through the strength, independence and completeness of the available evidence.

Reasoning pathways

Fixed Results and Uncertain Judgement

Possible route or outcome
01Known InputsVerified inputs and a fixed rule can produce a reproducible result.
02Fixed ResultThe output should be independently recalculable.
03Uncertain InputsIncomplete evidence requires probability, range or scenario analysis.
04Sensitivity and AlternativesTest how assumptions and competing explanations affect the result.
05Qualified ConclusionState confidence and reliance without presenting probability as certainty.

This visual flow is presented as an ordered set of labelled steps. Each step remains readable without animation or colour.

Two different tasks

Verification is not the same as judgment

Deterministic verification gates

Used where a matter can be tested against a defined record, condition, calculation or rule.

  • Identity, dates and chronology
  • Document and source existence
  • Citation accuracy and quotation context
  • Calculations and structural requirements
  • Directorships and necessary conditions
  • Whether apparent sources are genuinely independent

Structured probabilistic judgment

Used where several facts must be weighed and the record does not permit a binary answer.

  • Credibility of a representation
  • Strength of a market or transaction assumption
  • Significance of inconsistencies
  • Competing explanations
  • Materiality of evidence gaps
  • What further evidence could change the assessment

Three separate questions

Factual status, evidential confidence and reliance status

1. Factual status

What can be directly verified, contradicted, located, calculated or left unresolved?

2. Evidential confidence

How strong, independent, complete and current is the support for the broader conclusion?

3. Reliance status

Is the material sufficiently strong for the intended decision, its consequences and the cost of being wrong?

The same evidence may justify different levels of reliance depending on the decision, the potential consequences and the cost of being wrong.

Confidence language

Qualified, explained and never invented

Aperture does not assign precise percentages unless a defensible statistical model exists. Broader assessments may use qualified confidence levels:

High confidenceStrong, independent and materially complete support, with no unresolved issue likely to change the central finding.
Moderate confidenceMeaningful support exists, but one or more material uncertainties or plausible alternatives remain.
Limited confidenceThe finding is tentative because support is incomplete, dependent, conflicting or materially constrained.
Insufficient basis for confidenceThe available record does not responsibly support a broader conclusion.

What Aperture does not imply

Deterministic verification does not mean that a person, company, transaction or future event can be proved safe, unsafe or certain in every respect. Probabilistic judgment does not mean speculation, intuition or an unsupported AI confidence score.

Probability is not presented as certainty, and uncertainty is not concealed by polished language or numerical confidence scores.

Reality before reliance

Know what can be verified, what remains uncertain and what the decision can responsibly bear.
