AI answers sound confident whether they are right or not, so a quick check is worth the habit. Start by asking what would have to be true for the answer to be correct. Then pick the one claim the rest depends on and verify only that. A name, a number, a date or a rule is usually enough. Next, ask the same question a different way and see if the answer holds. If it changes, treat it as a guess. Finally, look for anything that sounds oddly specific with no source. Those are the details most worth confirming. Two minutes of checking beats an hour of fixing a mistake that went out under your name. What do you always double check?
