Ask ChatGPT for ten ideas right now, on anything: business names, marketing angles, gift options. Read the list top to bottom and watch what happens around number five. A Redditor over on r/ChatGPTPromptGenius flagged the exact same pattern and worked out why it happens.
Somewhere past the halfway point, the list starts circling back. Number 7 is number 2 wearing a different verb. Number 9 is 3 and 4 mashed together.
The model isn’t running out of things to say. It writes one item at a time, and each new item gets pulled toward whatever’s already on the page. By the second half, it’s mostly echoing the first half.
Run the check yourself before reading further. Ask for ten ideas on any topic, then scan the back half for anything that’s just a rewording of something earlier. You’ll find at least two.
Four Prompts That Break the Pattern 🔍
1. Force different starting points
Give me [10] ideas for [topic], each one from a different angle: [cost, speed, emotion, status, risk, habit, social, novelty, simplicity, fear]. One idea per angle, label the angle.
This works because it assigns a distinct lens to every item before the model starts writing. There’s no room to drift back to idea 2, because idea 7 has to come from risk, not from whatever idea 6 already covered.
2. Generate wide, then cut
Give me [30] quick ideas for [topic], one line each, no filtering. Then group them into clusters of near-duplicates and give me the single best idea from each cluster.
Thirty rushed ideas will repeat plenty, but that’s fine. The clustering step does the wait, these are the same work for you, so what survives is genuinely distinct.
3. Ban what’s already there
Here are the ideas I already have: [paste]. Give me [5] more that could not be mistaken for any of these. For each, say which of mine it’s furthest from.
Feeding the model its own output as a do not repeat list changes the task. It has to check new ideas against old ones instead of just continuing the pattern.
4. Count the real ones
Look at the list you just gave me. How many of these are genuinely different ideas, not rewordings? Merge the duplicates and tell me the honest count.
What Your List Is Actually Telling You
Run prompt 4 on any list of ten ideas and the model will usually admit to six or seven genuinely different ones. Not ten. The author calls this the eye-opener.
It’s easy to see why: you’re asking the model to grade its own homework, and it grades honestly when you ask directly. That’s the real lesson buried in this whole thread.
The model can tell the ideas apart when you make it look. It just doesn’t do that work on its own unless the prompt forces it. Left alone, it defaults to sounding productive instead of being original.
The creator behind this breakdown also builds AI Toolbox, a browser extension that adds a prompt library and folders to chat assistants. These four prompts are saved there with the blanks left in, so they paste in fast without extra setup.
You don’t need the extension to use any of this. Copy the prompt text, swap the brackets for your topic, and go.
A few commenters tested prompt 2 the same day the post went up and reported it worked right away on their own topics. That’s the fastest way to know a prompt is worth keeping: someone else runs it cold and it still holds up.
Extra Tips ✅
- Prompt 2 is the workhorse most commenters landed on. Thirty ideas cut down to clusters beats ten careful ones almost every time.
- Run prompt 4 on old brainstorm docs you already have sitting around. You’ll probably find the same repetition problem hiding there too.
- Stack prompt 1 and prompt 3 together: force different angles on the first pass, then ban repeats on anything you still need.
- Save these four somewhere you’ll actually find them again, a notes app, a doc, whatever sticks.
Next time a chatbot hands you ten ideas, don’t trust the list until you’ve run it through prompt 4. The honest count might surprise you!
Try the full set on your next brainstorm and see how many of your ten ideas turn out to be six 🎯. Then go read the original thread for the replies people are posting with their own results.
