Called it a bug based on a mental picture of "how it's normally done"

Making documents

Situation: Having an AI check whether an informational web page looks and behaves correctly.
What the AI did: It judged by a remembered model ("a normal product wouldn't do this") and reported a bug. Opening the product it had in mind and comparing showed the same behavior.
How to ask next time (the operator's example): "When you say 'normally it works like this,' open the product you're comparing against and try it in the same situation. Write down what you found."
One question to ask: Before saying "normally": was the product being compared actually opened?
Check it yourself: Ask which product the AI compared against, then open it and try the same step yourself. A claim about "standard behavior" that names no product can't be checked.
