how do you all handle the moment it confidently tells you something wrong?

the habit i've had to build isn't prompting, it's catching the confident wrong answer. it's great most of the time, which is exactly what makes the occasional confident mistake dangerous, it doesn't sound any different from the correct ones. my defense is asking for reasoning and sources on anything that matters, and staying most alert where i can't personally verify. but i know i've been fooled a few times. for daily users: what's your actual method for catching a confidently wrong answer before it costs you?
