How do you know if you can trust AI's output?

You do not trust it on sight, you check it. AI states a wrong detail as confidently as a right one, so fluent, confident writing is easy to mistake for correct writing. You can rely on the parts you have checked and the parts that do not matter much if they are wrong, and nothing else gets a free pass.

How do you judge whether AI output is good?

Judging output well means looking at three things, because AI can be strong on one and quietly failing another. Is it right: check the facts, figures, names and logic, because the model will state a wrong detail as confidently as a right one, so anything that matters gets checked. Is it fit for purpose: the right tone, length and audience, since output is often technically fine but not what you actually needed. Is the reasoning sound: for anything analytical, follow how it got there, not just the conclusion, because a good answer reached for a bad reason will not hold up.

How do you spot when AI is subtly wrong?

The subtle errors hide behind confident, well structured writing, so you cannot rely on how it reads. Follow the reasoning rather than the conclusion: trace how it reached the answer, because a good answer reached for a bad reason will not hold up. Watch the process over several rounds too, since you can notice an idea you had already rejected quietly creeping back into the work.

What should you do when AI gives you the wrong thing?

Treat it as a loop rather than a verdict. Description and discernment work together: you brief, you judge what comes back, then you adjust the brief and go again, and most of the skill is going round that loop quickly instead of accepting the first thing you get. When you flag the problem, say what is wrong and why, not just that you dislike it, so the next version actually moves. If better briefing keeps failing, the problem may be further back, in what you handed to AI in the first place.
