Everyone knows AI hallucinates. It invents facts, fabricates sources, generates confident nonsense. That problem gets all the attention because it is dramatic and easy to demonstrate. Ask ChatGPT for a legal citation and it invents one. Ask it for a study and it makes up the numbers. These are obvious failures, and most experienced AI users have learned to watch for them.
The problem nobody talks about is worse. AI does not just fabricate from nothing. It takes your real information, the accurate data you gave it, and distorts it back to you. It rounds your numbers. It swaps your details. It inflates your claims. It shifts your timeline. And it presents the distorted version with exactly the same confidence as the original.
I use AI every single day. I have written 45 handbooks on AI-assisted writing. I consult with businesses on AI integration. I am not speculating about this problem. I have watched it happen with my own data, repeatedly, across thousands of hours of AI use.
What Distortion Looks Like
Pure hallucination is easy to describe. For more, see your AI vendor just murdered your kids' future (and you pay . You ask AI a question, it does not know the answer, so it generates something plausible. A fake study, a fabricated quote, an invented statistic. You can catch this by checking whether the source exists. If it does not exist, the AI made it up. Simple.
Distortion is different. You give AI accurate information, your real numbers, your actual experience, your verified data, and over the course of a conversation or across multiple sessions, the AI drifts the details. Not dramatically. Not obviously. Just enough that the output sounds like your information but is no longer accurate.
I have seen AI take a specific number and round it up to something more impressive. I have seen it take a precise claim and generalize it into something broader than what I said. I have seen it swap similar details, confusing one client outcome with another, merging two separate events into one, shifting a timeline by years. Every time, the distorted version sounds plausible because it is built on a foundation of real information. The skeleton is mine. The details have been changed.
This is harder to catch than pure hallucination because you recognize your own material. When AI invents something from nothing, it might trigger a “wait, that does not sound right” reaction. When AI distorts something you actually said, your brain fills in the correct version because the output is close enough. You read it, it sounds like your stuff, and you move on. The error passes through your review because the context is familiar.
Why AI Does This
AI does not distort information on purpose. It does not understand the difference between “close enough” and “accurate.” It is a pattern-matching system that generates the most statistically likely next word based on context. When you give it specific data, it processes that data the same way it processes everything else, as patterns to be reproduced approximately.
The word “approximately” is the problem. When you tell AI you have completed 54+ projects, it does not store “54” the way a database does. It processes “54” as part of a pattern that includes “experienced professional with many completed projects.” Over a long conversation or across repeated interactions, “54” can drift to “over 50” or “more than 50” or “nearly 60” or “over 100” because all of those fit the pattern of “experienced professional with many completed projects.” The AI is not lying. It is approximating, and approximation is not accuracy.
The same thing happens with names, dates, locations, dollar figures, and specific claims. AI treats specific data as instances of general patterns, and when it regenerates that data, it sometimes regenerates the general pattern rather than the specific instance. Your exact dollar figure becomes a range. Your specific city becomes a region. Your precise timeline becomes “several years.” Each drift is small. Each drift is plausible. And each drift makes your information less accurate without making it obviously wrong.
Where It Gets Dangerous
The danger is not in casual conversation. If AI rounds a number in a chat message, nobody gets hurt. The danger is in professional contexts where accuracy matters.
If you are using AI to help draft a business proposal and it inflates your track record, your proposal now contains false claims. If you are using AI to help write a book and it shifts a date or merges two events, your book now contains errors that you presented as fact. If you are using AI to help prepare a presentation and it generalizes your specific data into broader claims, you are now presenting information you cannot back up.
In every case, the person using AI believes the output is accurate because it is based on their own real information. They gave AI the correct data. They expect the output to reflect what they provided. They review the output and it looks right because it is built on their material. The distortion passes through review, gets published or presented, and becomes the official version.
I have seen professionals discover months later that AI-assisted content contained distorted versions of their own data. By then the distorted version has been published, shared, cited, and repeated. Correcting it requires not just fixing the original but tracking down everywhere the wrong version spread. This is a credibility problem that is entirely avoidable if you know what to watch for.
The Compounding Problem
Distortion compounds. If you use AI across multiple sessions and reference your own previous AI-assisted output, each session can drift the data further from the original. Session one rounds a number. Session two uses the rounded number as input and generalizes it further. Session three takes the generalization and inflates it. By session five, the number AI is working with may bear little resemblance to the original, and every step of the drift felt natural and plausible because each individual change was small.
This is particularly dangerous for people who use AI extensively in their daily work, which increasingly means everyone. The more you rely on AI to process and reproduce your own information, the more opportunities there are for cumulative drift. Each individual distortion is minor. The accumulated effect over months of daily use can be significant.
I have caught distortions in my own AI-assisted work that I would not have noticed if I were not specifically watching for them. I know my own data well enough to spot when a number has shifted or a detail has been swapped. Most people do not have that level of familiarity with every piece of data they feed into AI, which means most distortions go unnoticed.
How to Catch It
The first step is accepting that this happens. Not occasionally, not rarely, regularly. For more on AI as assistant, not author, hear Richard on Tequila and Tech Talk. AI will distort your data. The question is whether you catch it before it goes out the door.
Verify specific numbers every time. If your AI output contains a number, a dollar figure, a date, a count, a percentage, a measurement, check it against your original source. Do not check it against what you remember. Check it against the actual record. Memory is unreliable, and AI-distorted data can overwrite your memory of the correct figure if you see the wrong version enough times.
Watch for inflation. AI has a consistent tendency to make things sound more impressive. Numbers round up, not down. Timelines get longer. Scope gets broader. Claims get stronger. If the AI output makes you sound slightly better than reality, that is probably distortion, not accuracy.
Keep a reference document with your verified facts. Your actual numbers, your real timeline, your specific claims, written down and accessible so you can cross-reference AI output against confirmed data rather than against memory. Update it when things change. Use it as a checklist when reviewing anything AI helped produce.
Be especially careful with long conversations. The longer a conversation runs, the more opportunities for drift. If you are working with AI on a complex project over multiple sessions, re-anchor the key data at the start of each session by providing your verified facts fresh rather than relying on AI to remember them correctly from previous context.
Review AI output as if someone else wrote it. The reason distortion slips through review is that you recognize your own material and your brain fills in the correct version. If you read AI output the way you would read someone else’s draft, checking every specific claim rather than skimming familiar content, you will catch distortions that casual review misses.
AI Is Still Worth Using
None of this means you should stop using AI. I use it every day. It is extraordinary for brainstorming, research, organization, analysis, and accelerating work that would otherwise take hours. The productivity gains are real and substantial. The 2024 Gotham Ghostwriters survey of 1,481 writers found that advanced AI users report a 31% average productivity increase and median incomes $47,000 higher than nonusers.
But those gains come with a responsibility to verify. AI is a tool that processes information approximately. Approximately is useful for brainstorming. Approximately is useful for first drafts. Approximately is not acceptable for published content, client deliverables, business proposals, or anything where your credibility depends on accuracy.
The writers and professionals getting the best results from AI are the ones who use it aggressively for speed and then verify aggressively for accuracy. They do not trust AI output because they provided the input. They check it precisely because they know the distortion problem exists.
Use AI for what it does well. Verify everything it produces. And never assume that because you gave it the right information, it gave you the right information back.
