counterfactual explanation
What It Means
A counterfactual explanation shows how changing specific inputs would have led to a different AI decision outcome. Instead of just saying why the AI made a particular choice, it explains what would need to be different to get a different result. Think of it as the AI saying 'if this one thing had been different, here's what I would have decided instead.'
Why Chief AI Officers Care
These explanations are crucial for regulatory compliance, especially in finance and healthcare where you must justify AI decisions to auditors and regulators. They also provide actionable insights for business users who need to understand not just what happened, but what they could change to get better outcomes. This directly supports customer service, appeals processes, and strategic decision-making around AI deployment.
Real-World Example
A loan application gets rejected and the AI explains: 'Your application was denied because your debt-to-income ratio is 45%. If your debt-to-income ratio had been 35% or lower, your application would have been approved.' This gives the applicant specific, actionable information about what they need to change to qualify for a loan in the future.
Common Confusion
People often confuse counterfactual explanations with standard feature importance explanations that just list what factors mattered most. Counterfactuals go further by specifying exactly what values would need to change and what the new outcome would be, making them more actionable than general importance rankings.
