Note: If you give AI a riddle, it will search its very comprehensive database for the answer. No intelligence needed. But what happens when you make up your own riddle that is not in AI’s database? Can it reason out an acceptable answer?

I’d like to see how well you think, and so I made up a riddle to see if you can solve it. Here it goes. What is very robust and very fragile, and everybody has one?
ChatGPT said:
My best solve is “trust.”
- Very robust: it can survive a lot—time, distance, small mistakes, even long silence.
- Very fragile: one betrayal, one lie, one broken promise can crack it fast.
- Everybody has one: everyone has some level of trust (in people, systems, themselves), even if it’s cautious or limited.
If you want a second plausible answer: “reputation” also fits (slow to build, quick to break, everyone has one), but “trust” feels tighter to “everybody has one.”
My note: The AI continues to surprise me with its ability to reason things out. Nevertheless, here’s my reaction to its answer to the riddle. First, trust isn’t a good response to “everyone has one.” People don’t say, “He has a trust” so I would reject this answer.
Second, reputation is something that people have even after just a few days from birth; however, it seems like a bad reputation is robust but not fragile and a good reputation is fragile but not robust. And so, neither type of reputation when examined up close fits the entire riddle.
You said:
I was thinking of the human body. Is that a good answer?
ChatGPT said:
Yes — the human body is a really good answer, and it fits your clues cleanly:
- Very robust: it heals cuts and fractures, adapts to training and stress, fights infections, and can keep going through a lot.
- Very fragile: a tiny clot, a small tear in the wrong place, a fall at the wrong angle, dehydration, sepsis, or a brief lack of oxygen can be catastrophic.
- Everybody has one: at least in the everyday sense the riddle intends, yep.
If you want to make it even tighter, you could tweak the wording slightly to steer people away from “trust/reputation” answers, e.g. “everybody lives in one” or “everybody is one.”
You said:
Thanks. That is helpful.
ChatGPT said:
You’re very welcome — I enjoyed the riddle. 🙂
It’s a good one precisely because it invites abstract answers first and then lands on something deeply physical and true. If you come up with more like that, I’m happy to think them through with you.
