false negative

What It Means

A false negative occurs when your AI system incorrectly says 'no' or misses something it should have caught. The system fails to identify or flag something that actually exists or should be detected. Think of it as your AI being overly cautious and missing real opportunities or threats.

Why Chief AI Officers Care

False negatives directly cost your business money through missed opportunities, undetected risks, or regulatory failures. In critical applications like fraud detection or medical diagnosis, missing real problems can lead to significant financial losses, legal liability, and damaged customer trust. Unlike false positives that create extra work, false negatives create invisible gaps in your operations.

Real-World Example

Your credit card fraud detection system fails to flag a $5,000 purchase made with a stolen card in another country, allowing the fraudulent transaction to go through. The system incorrectly classified this suspicious activity as legitimate, resulting in a direct financial loss and potential customer dispute.

Common Confusion

People often confuse false negatives with false positives - remember that false negatives are about missing the bad stuff, while false positives are about incorrectly flagging good stuff. False negatives are often harder to spot because you don't know what you're not seeing.
