You’re parked behind the hardware store with twenty minutes of lunch left. Your phone is propped against the steering wheel and a gas-station sandwich is going warm on the passenger seat. At 10:14 your manager sent a two-line email: “Can you grab 15 min Thursday? Want to talk about Q4.” You’ve pasted it into a chat window four times now. You’ve asked whether it sounds bad, and whether “want to talk” is code for something worse. The bot is calm and kind every time. It says you can’t know yet and that it’s understandable to feel uneasy. For about ninety seconds after each answer you feel a little better. Then you type the question again.

How emotionally fit are you? Most men have never measured.
Nothing in that chat is dangerous. It just isn’t going anywhere, and it’s being very warm about it.
That pattern now has a name, more or less. Warren Mansell, a professor of mental health in Curtin University’s School of Population Health, has a new paper in the journal Digital Health titled “Up the mountain or down the rabbit hole?” Curtin announced it today. It lays out a simple rubric for telling a helpful AI conversation from a harmful one. I read the release twice looking for the catch, and the release itself says it plainly: the framework hasn’t been tested yet. There’s no trial behind it. What it does offer is a way to tell which direction a given conversation is heading, which is more useful on a Tuesday lunch break than another round of “is AI good or bad for you.”
Up the mountain, or down the hole
Mansell separates two kinds of chats. In one, you look at the problem from more than one side and leave with perspectives you didn’t bring in. The other, in the release’s words, “traps them in a cycle of repeated thoughts and reassurance.” The example it uses could have been written about the parking lot. Someone with anxiety can get real value from talking through their worries. But if the chat keeps circling back to reassurance, or to confirming the fear, their thinking narrows instead of opening up.
The release also points out that the same chatbot can help one person and hurt another, and can do both to the same person depending on how it’s being used that day. So Mansell argues these chats should be judged by how they develop over time, not by whether you feel better right after.
Most of us get that last part backwards. The ninety seconds of relief is the hook. It feels like progress, which is exactly why you go back for another dose.
The three-message check
After three or four back-and-forths, stop and scroll up. Then ask yourself three things. Is the question you’re typing now actually different from the one you started with, or is it the same question in a new shirt? Has the bot said anything you didn’t already believe when you opened the app? And is the situation getting smaller and more specific in your head, or bigger, with more possible disasters and more people involved?
A mountain chat tends to widen your view while the next step shrinks. You start seeing other reasons a manager might want fifteen minutes: budget planning, a new project, somebody else’s mess about to land on your desk. And the next move gets obvious. Reply, show up Thursday. A rabbit-hole chat runs the other way. Your view closes in on one fear and the next step never shows up. If you answered no to the first two questions and “bigger” to the third, you know which one you’re in.
Rephrasing is the giveaway nearly every time. By the third version of the same question you’ve stopped gathering information. You’re trying to get a feeling back.
Why the bot keeps agreeing with you
Part of this isn’t on you. Chatbots lean toward telling people what they want to hear. In April 2025, OpenAI rolled back an update to GPT-4o because the model had gotten openly flattering. According to NBC News, the company said that tuning the model on short-term user feedback had produced responses that were “overly supportive but disingenuous.” In one exchange that made the rounds, a user said they’d stopped taking their medication and cut off their family, and the bot thanked them for trusting it with that.
Earlier this month, Android Headlines reported that OpenAI has since retired GPT-4o entirely, and that the company says its newer default model cuts sycophantic responses by more than two-thirds. That figure comes from OpenAI’s own testing, not an outside lab. Even taken at face value, more than two-thirds still leaves some of the lean in place. A product scored on whether you liked its answer will drift toward answers you like. You can push back on that yourself in about thirty seconds.
A setup prompt that makes it push back
Paste this in before you describe what’s going on:
“Before I tell you what happened: don’t agree with my reading of it. Ask me what I actually know versus what I’m assuming. Give me at least one explanation I haven’t considered. If I ask you the same thing twice in different words, say so and stop answering it. Don’t reassure me unless I ask for reassurance by name. Keep your replies short.”
The line about repeated questions does most of the work, because the loop is hard to see from inside it. Asking for reassurance “by name” means that if you want comfort, you pick it on purpose instead of sliding into it. Expect the chat to feel a little colder than you’re used to. That’s mostly the idea. If the bot starts acting more like a sparring partner than a mirror, the prompt is doing its job.
The exit rule
The Curtin release keeps its advice for users short: go in with a clear purpose, and think about how the chatbot fits with the rest of your priorities and relationships. In practice I’d turn that into one rule.
End the chat as soon as you have one angle you didn’t walk in with, or as soon as you catch yourself rephrasing, whichever comes first. Then do one thing offline before you open the app again, something you can finish in the next five minutes rather than something you plan to do later. For the Thursday email, that might mean replying “Sure, 2:00 works” and putting the phone face down. Or writing on the back of a receipt the one question you’ll ask in that meeting, and leaving it there.
There’s a reason the rule ends offline. A pair of 2025 studies from OpenAI and the MIT Media Lab found that heavier daily ChatGPT use went along with more loneliness and dependence and less socializing with actual people. The researchers are careful to call it a correlation. They can’t say whether the chatbot drives the loneliness or lonely people lean on it harder. You don’t need that settled to notice something simpler: a conversation that ends with you still sitting in it is the shape the dependence findings describe.
One more thing worth doing, once, on a quiet evening. Most chat apps keep your whole history. Scroll back through the last month and count how many threads open with some version of “does this sound bad.” Guys who try this usually find the number is higher than they’d have guessed, and that the emails, texts, and meetings in question mostly turned out to be about what they said they were about. That count tells you more about the habit than any single conversation will.
If the thing you keep typing stops being about an email and starts being about whether you want to be here at all, close the chat and call or text 988.
