AI never gets it 100% right. Everything else follows from that
When AI creates something — text, code, anything — it is not a machine that produces the same correct result for the same brief every time. Every task is a bit of a dice roll: some things land, some don't.
A weaker model rolls badly. Imagine the correct result only comes up on a four, five or six — out of ten tasks, it gets half wrong. A top model rolls much better: out of a hundred tasks it lands, say, 95. But a hundred out of a hundred never happens. With any model. Today or tomorrow.
That sounds like bad news, but it isn't. It just means one thing: there's no point hoping the mistake won't come. There is a point in setting up the work so the mistake finds itself — immediately, not after it has done damage.
The golden rule: let AI check its own work
When AI can verify its own work, it also fixes most of its own mistakes — quickly, without you having to sit over it. So with every task, think about one thing: give it that ability.
A programming example: when AI builds a website, let it run the site and look at it with its own eyes — exactly like a human developer would. It will see what's off and fix it before you ever see it. The same applies everywhere: it can re-read a document, verify a calculation, click through a spreadsheet.
The second trick: request a self-review as a separate task
While creating, AI doesn't review itself — it focuses on making, not checking. But when you assign the review as a separate follow-up task (“check your own work”), it very often finds mistakes and things it can still improve. It's the same dice — but you're rolling it a second time, and two bad rolls in a row are far less likely than one.
For anything important, always ask for this second loop. It costs seconds and catches exactly the mistakes your customer would otherwise find.
Remember
- Every task is a dice roll — even the best model doesn't roll right every time.
- Set up the work so AI can check itself automatically — then it fixes most mistakes on its own.
- For important work, request a self-review as a separate step.
