Definition

An analytics concept defining statistical methods used to estimate relationships, evaluate interventions, and generate forecasts. It specifies data requirements, estimation procedures, and uncertainty measures used to support decision-making. It does not prove causation without an appropriate identification strategy, data quality checks, and sensitivity analysis. It supports performance management by translating data into estimates, predictions, and quantified uncertainty. The concept is generally stable, though tooling and best practices for measurement evolve over time.

Principle

Principle
Causal inference rests on articulating counterfactual contrasts, specifying identification assumptions (randomization, ignorability, exclusion restrictions, continuity), and using design or statistical adjustments to estimate causal effects while making explicit untestable assumptions.

Demonstration

Demonstration
An RCT that randomizes job training participation provides an unbiased estimate of the program's effect on wages; when randomization is infeasible, an instrumental-variable strategy uses proximity to training centers as an instrument, or a difference-in-differences compares pre/post outcomes across treated and control groups around a policy change.

Misapplication

Misapplication
Reading a regression coefficient from observational data as a causal effect without assessing confounding, using a weak or invalid instrument, or conditioning on post-treatment variables and thereby inducing bias.

Consequence

Consequence
When identification assumptions are credible and satisfied, causal inference yields estimates that support counterfactual questions and policy decisions, such as expected impacts of scaling an intervention or allocating resources.

Reversal

Reversal
Prediction-focused modeling that optimizes out-of-sample accuracy without interpreting coefficients as causal effects; inverting causal inference into predictive claims ignores the counterfactual aim and can mislead policy choices.

Boundary

Boundary
Applies to statements about interventions or exposures; does not automatically follow from association; many causal methods require assumptions that are inherently untestable with observed data and may be sensitive to model specification and sample selection.

Semantic Tension

Semantic Tension
Frequently conflated with predictive modeling or simple associational analysis; the tension lies between association (what is observed) and causation (what would happen under an intervention) and between design-based versus model-based identification strategies.

Synthesis

Synthesis
Causal inference is the toolbox and reasoning framework that combines study design, assumptions and estimation strategies to answer counterfactual questions about interventions, always conditioned on explicit identification assumptions and sensitivity to their plausibility.
