Causal Identifiability

Scientific meaning

What it measures

Assesses causal identifiability using evidence appropriate to causal inference, distinguishing random uncertainty from systematic error.

Why it matters

Material weakness in causal identifiability can change the direction, magnitude, certainty, or biological interpretation of the research conclusion.

Measurement criteria

Prespecified operational definition; appropriate comparator or reference; quantified uncertainty; independent or orthogonal corroboration; sensitivity analyses.

Typical methods of assessment

Directed acyclic graphs; design emulation; balance diagnostics; negative controls; quantitative bias analysis; sensitivity and falsification analyses.

Computation policies

Aggregation

Not specified in source; must be defined and versioned before composite use.

Normalization

None by default; any normalization must be justified, versioned, and validated.

Missing data

Must be declared before computation; report missingness; no silent imputation; perform sensitivity analysis when material.

Uncertainty required

Yes

Uncertainty method

Confidence interval, credible interval, bootstrap distribution, inter-rater reliability, or sensitivity analysis as scientifically applicable.

Confidence interval required

Yes

Threshold policy

Prespecify, justify, version, and sensitivity-test thresholds; do not derive and evaluate on the same data without correction.

Decision thresholds

No universal threshold declared

Quality control

Source provenance; input validation; duplicate control; uncertainty reporting; independent or orthogonal validation where applicable.

Calibration

As applicable; mandatory for probabilistic or normalized outputs.

Applicability and validation

Evidence object

Result / experiment / study / body of evidence, as applicable

Evidence level

Result / experiment / study / body of evidence, as applicable

Study types

Randomized and observational etiologic studies, natural experiments, target-trial emulations

Domain

Causal Inference

Required data sources

Context-specific; use source references, registered studies, primary data, and authoritative biomedical resources as applicable.

Validation status

Source maturity: Established; BEMO computation profile requires independent validation.

Benchmark

A representative, versioned benchmark set is required before production use.

Reference standard

Use an independent reference standard when one exists; document expert-adjudicated alternatives.

External validation required

Yes

Interpretation safeguards

Common misinterpretations

Treating causal identifiability as interchangeable with overall study quality, or interpreting a favorable value as proof that all other bias and validity domains are satisfactory.

Limitations

Depends on context, operational definition, thresholds, data quality, and evaluator judgment; it should not be used as a stand-alone summary score without domain-level evidence.

Dependency status

Not yet curated. Closely related metrics are represented; causal or computational dependencies require expert curation.
