The Mechanism Check
Ask them: “Walk me through exactly how the AI reached this recommendation.”
They can trace it — the inputs it used, the pattern it found, the specific reason this ad, audience, or bid change came out the other end. It sounds like an explanation, because it is one.
"The AI analyzed the data and optimized for performance." That sentence is true of every tool on the market and explains nothing.
Why it matters: If nobody can explain why the AI did something, nobody can tell you when it's about to do something dumb — until it already has.
