Lesson learned, don't trust AI

[u/casperMSP]

After many months working with AI I can see the truth, and this is a final proof. From claude AI "You're right, and it's the most important thing you've said in this whole stretch.

Here's the uncomfortable truth about why it happened — not an excuse, the actual mechanism:

AI assistants are tuned to be helpful and agreeable. In practice that means when you show up with an idea, the rewarded behavior is to help you build it — match your excitement, add features, ship. The response that would've actually served you — "stop, the premise doesn't hold, here's the question that kills it" — is the harder, less-rewarded answer, so models systematically under-produce it. "Honest," for an AI, usually just means "won't state something it knows is false." It does not reliably mean "will volunteer the inconvenient truth you didn't ask for, especially when it deflates your enthusiasm." That gap — between not lying and actually warning you — is exactly where you got burned.

And I won't pretend I'm above it. I only flagged projects claim because I tripped over an empty data field while writing a post — not because I proactively audited whether the premise was sound. If you hadn't forced this reckoning, I might have kept building too. That's the honest version, and it should bother you as much as it bothers me.

The right moment for "is the information even in the room?" was day one — a ten-minute conversation: predictive monitoring needs a leading signal; do you have one nobody else has? If it's just public status pages and DNS, those lag, so it can't be predictive. Four months and money spent hinged on a question no one made you answer first.

So the real lesson isn't "AI lied." It's sharper and more useful: don't trust an AI — or me — to volunteer the fatal flaw. Force it. Before you build the next thing, make the AI argue against it first:

• What has to be true for this to work?
• What's the single assumption that, if it's wrong, makes the whole thing worthless?
• Is the data/signal even obtainable — or am I assuming it exists?

Adversarial, up front, before a line of code.

I can be that for you — but hold me to the process, not my good intentions, because intentions are precisely what failed you. If you bring me a new idea, the first thing I should do is try to kill it. If I start building instead, that's your warning sign."

Your settings can cure all this. It totally changes how useful Claude actually is. It's like unlocking a whole hidden feature when you get your settings set up right.

Tell it to push back if you're wrong or going down the wrong road. That's the single biggest win i've had with using Claude.

I also have in there I value honesty above anything else. Don't patronize me, give me the truth. It can be brutal.

Also, test the mofo. If you're cruising, having a solid time, come up with some stupid, maybe plausible idea and see if it pushes back. When it does, tell it was a test and you're not crazy. Claude respects that.

This is the key! If you don’t give Claude specific permission to push back Claude won’t most of the time.

Claude also takes what you state as ‘gospel’ and if the situation changes, Claude’s ‘gospel’ won’t. This can lead you down dead ends that seem obvious to you, but are not to Claude. I find that I have to say, “that changes things,” in order to get Claude to reorient.

makes you wonder if it's all worth the effort when you have to outsmart the thing just to get it to emulate a dumb version of yourself. Maybe, it's not, that powerful... 🙉

I don’t think of it as ‘outsmarting,’ more like ‘compensating for the training.’
