type I error
What It Means
A Type I error occurs when your AI system incorrectly flags something as positive when it's actually negative - essentially a false alarm. It's like a security system that goes off when there's no actual threat, or a fraud detection system that blocks legitimate transactions.
Why Chief AI Officers Care
Type I errors directly impact customer experience and operational costs because they create unnecessary friction and false positives that require human intervention to resolve. High Type I error rates can damage customer trust, increase support costs, and reduce system adoption across the organization.
Real-World Example
A credit card fraud detection system that blocks a customer's legitimate purchase at a gas station because the AI incorrectly identified normal spending patterns as suspicious activity, forcing the customer to call the bank and creating frustration while generating unnecessary operational costs.
Common Confusion
People often confuse Type I and Type II errors, mixing up which is the 'false positive' versus 'false negative.' Remember Type I as 'false positive' - the system incorrectly says 'yes' when it should say 'no.'
