Where it slips up

AI's big catch: it can be confidently wrong. It states made-up things in the exact same calm, certain voice it uses for true ones — so the only safe move is to check what matters.

The one idea to keep: AI predicts plausible words, not verified facts. It sounds sure either way — so your job is to check, not to trust the tone.

See for yourself. You asked AI for three quick facts — pick the one you think it made up:

Spot the made-up one

Several rounds of "quick facts." Each one the AI states with the same calm certainty — but one per round is invented. Catch it, see why it was made up, and learn the one-line way you'd check.

Honey never really spoils — sealed pots thousands of years old have been found still edible.

Bees make honey from the nectar they gather from flowers.

A single worker bee makes about a full jar of honey in its lifetime. ✗ this is the invented one

Built so you get it by trying it — Bret Victor's idea of an explorable explanation.

That's the whole pitfall in one go. AI is fluent, not accountable — it has no internal sense of true versus false, only of what words usually come next. The fix isn't to distrust it; it's to keep a human check on anything that matters. That check is the heart of augmented intelligence: you let AI do the work, and you stay the one who verifies and decides.

Why can't you trust an AI answer just because it sounds confident?

It predicts plausible words, not verified facts — so it states made-up things in the same confident voice as true ones. Confidence tells you nothing about truth; verify anything that matters.

Try it on your own work

Next time you lean on an AI answer for something that matters — a fact, a number, a recommendation:

  1. Take its most confident-sounding claim.
  2. Check it against a real source — and notice how convincing the wrong version can look.

If you can't think of a way to check a task, that's the task to keep a closer eye on.
