Counterfactual Fairness Tool
Would the decision change if only the protected attribute were different?
Asks whether a model decision would change if one protected attribute, and nothing else, were different.
What it does
You import the causal model, set the production decision threshold and enter factual and counterfactual predictions case by case. You get the decision flip rate and a sensitivity verdict tied to the causal paths, which the Intervention Planner reads.
Why it matters
This step evaluates whether individual outcomes would change under counterfactual variations of protected attributes, given the causal model. It provides evidence of individual-level unfairness and helps localize discrimination to specific causal paths.

How to use it
In the Fairness Navigator Beta
Work through the steps in order. Several modules open from the Navigator's steps and hand their results back.
On its own Live
Open 3.2.1 from the platform's Modules page and run it when your project needs it. Work is saved with the assessment.
After a Pulse reading Live
Start with a fast first read, then go deeper with the modules where it points.
