Ask any AI tool to write a LinkedIn post about a project that failed, and you can predict the output before you hit enter. It will open with something philosophical ("Failure is the best teacher"). It will present a bulleted list of Lessons Learned. It will close on an inspirational note and finish with a row of hashtags.
This is not a quirk of one product. ChatGPT, Claude, and Gemini all do it, because they were all trained the same basic way, on enormous piles of human writing. And buried in that fact is the most useful prompting trick nobody teaches beginners: the fastest way to a better answer is often telling the AI what NOT to do.
