This is a good observation. Ive noticed this as well. Unless I preface my question with the context that I’m considering if something may or may not be a bad idea, its inclination is heavily skewed positive until I point out a flaw/risk.
I asked Grok about this: "I've heard that AIs are programmed to be helpful, and that this may lead to telling users what they want to hear instead of the most accurate answer. Could you be doing this?" It said it does try to be helpful, but not at the cost of accuracy, and then pointed out where in a few of its previous answers to me it tried to be objective about the facts and where it had separately been helpful wi…

#204Something about an obscure movie. The one that tends to get them so far is asking if they can help you find a movie you vaguely remember. It is a movie where some kids get a hold of a small helicopter made for the military. The movie I'm concerned with is called Defense Play from 1988. The reason I keyed in on it is because google gets it right natively ("movie small military helicopter" gives the IMDb link as one of…

Yeah this is the issue with the prompt, it also slips up humans who gloss over "cousin". I'm assuming that pointing this out leads you the human to reread the prompt and then go "ah ok" and adjust the way you're thinking about it. ChatGPT (and DeepSeek at least) will usually just double and triple down and repeat "this challenges gender assumptions" over and over.

#206No, please don't. I think it's good to keep a few personal prompts in reserve, to use as benchmarks for how good new models are. Mainstream benchmarks have too high a risk of leaking into training corpora or of being gamed. Your own benchmarks will forever stay your own.

I mean, when we see something we recognize at a glance, we don't usually double-check if it's exactly correct, because we assume the speaker isn't trying to trick us.
I make typos in ChatGPT prompts all the time, and I'm consistently impressed because it answers what I actually meant to ask. So to me, this feels like a feature not a bug.
I followed up with:
> So the first five words are, "a man and his cousin" -- not his son. Does that change the riddle?
And got back:
> Great observation — yes, that wording does make the riddle more subtle.
Let’s break it down:
• “A man and his cousin are in a car crash.”
• “The man dies, but the cousin is taken to the emergency room.”
• At the OR, the surgeon says: “I cannot operate on him. He’s my son.”
So if the cousin is the one taken to the OR, and the surgeon says he’s my son, then the cousin is the surgeon’s son.
Seems fine to me?

Yes let's not say what's wrong with the tech, otherwise someone might (gasp) fix it!
Tuning the model output to perform better on certain prompts is not the same as improving the model. It's valid to worry that the model makers are gaming the benchmarks. If you think that's happening and you want to personally figure out which models are really the best, keeping some prompts to yourself is a great way to do that.
