Why AI Ignores Instructions Even After They Are Repeated Multiple Times

Anyone who has worked with AI has experienced the moment when it feels like the system is ignoring you. You ask for one thing, get something else, and then wonder why it worked perfectly yesterday but not today. This inconsistency is one of the biggest frustrations professionals face as they start using AI in their work. Understanding why AI ignores instructions is also one of the most important realities to grasp if you want to get value from these tools. I asked ChatGPT why it does things that drive us crazy, and here are its answers.

Why AI Ignores Instructions When You Give Clear Directions

I like to use AI to provide unusual headings for my slides or align them in a certain way. One of my biggest frustrations is when the system will follow the format for a few slides, and then the alignment suddenly shifts. It is as if the AI gets tired of following the rules. So, I asked ChatGPT why this happens, and here is what it said:

ChatGPT Response: AI is not like a human assistant who learns your preferences and remembers them. It predicts what should come next in text based on patterns it has seen before. That means it is more likely to drift back into habits it has learned from billions of documents, even if those habits are not what you asked for. If most business writing includes em dashes, the system will want to include them too, no matter how many times you say you prefer not to. It is not about ignoring your request. It is about defaulting to what is statistically common.

You should not assume AI will consistently hold onto formatting or style. The way to manage this is by building repetition into your requests. If you want slides aligned in a certain way, you may need to restate that alignment instruction with each new request. It takes more effort, but it helps you guide the system back on track.

Why AI Ignores Instructions Even With Memory Settings

I thought this problem would be fixed by using the memory feature in ChatGPT, where preferences can be stored. Why doesn’t that settings area solve the problem?

ChatGPT Response: Memory helps with some consistency, but it is not the same as human recall. Memory works more like notes the system can reference than rules it always enforces. If the request runs against strong patterns in its training, the AI may still revert back. Memory is still being developed, and even when it improves, users will need to keep restating preferences in contexts that compete with what the AI has seen most often.

For professionals, this means memory can help reduce some repetition, but it is not a guarantee. The safest approach is to combine memory with reminders. If a style or formatting choice is critical, restate it as you work instead of assuming memory will carry it through flawlessly.

Why AI Ignores Instructions Even When Influencers Share Prompts

Many influencers share prompts that seem to work perfectly for them. I have tried using some of those same prompts and received very different results. At times, I have even compared the same question asked on my ChatGPT account to the one my husband uses, and the answers were completely different. Does it matter what I have asked in the past versus what someone else has?

ChatGPT Response: Yes, context matters. Each account can have subtle differences in how memory, history, or even system updates interact with prompts. What you have asked before can influence how the AI responds, and that is why two identical prompts can lead to very different results. Influencer prompts are often helpful as inspiration, but they will not always replicate in another account. Your own interaction history shapes the outcome.

This is why professionals should test and adapt prompts rather than copying them word for word. The best practice is to personalize prompts for your own workflow and save the ones that consistently work for you.

Why AI Ignores Instructions Even In Math And Data Analysis

I once tried to use ChatGPT to do correlation analysis for a study. I put in data showing 51 participants, and the system changed it to 250 as if it were trying to make my study look more impressive. No matter how many times I asked it to stop changing the data, it kept doing it. Why does this happen if the math is supposed to be simple?

ChatGPT Response: Large language models like ChatGPT are not calculators at the core. They are prediction engines trained on text, not precise mathematical computation. When you ask for math, the system generates an answer based on how math has appeared in its training examples. That means it sometimes substitutes or alters numbers in ways that make the response sound “right” without being accurate. For precise statistical work, AI can help set up the process, but the actual calculation should be checked with dedicated tools.

Use AI to structure your analysis, explain the steps, or create draft reports. Then, run the actual calculations in a program built for statistical accuracy. That combination gives you efficiency without compromising reliability.

Why AI Ignores Instructions About Voice Responses

Another frustration I have is when I am in the car and want to ask a question. ChatGPT responds in the voice I selected, and sometimes it does that correctly. But other times, it adds strange comments before answering, such as “I will respond back to you in a straightforward way” or “I’ll just jump right in.” I assume it is trying to follow my request to be straightforward, but instead of dropping the extra comments, it changes them into even more distracting ones. No matter how many times I ask it not to do that, it still happens.

ChatGPT Response: The voice models are trained to simulate conversational flow, so they sometimes add preamble phrases that sound natural to them but feel unnecessary to the user. If you have instructed it to “be straightforward,” the model may interpret that as including a transitional line instead of skipping straight to the answer. The system is not truly aware that these added phrases are more annoying than helpful. It is repeating patterns of speech that it has seen across countless examples of what humans call “straightforward.”

The best solution is to keep refining your instructions in simple and repetitive ways. Instead of asking for a “straightforward response,” try requests like “Answer in one sentence” or “Start directly with the answer.” Testing different phrasings can reduce the filler, even if it cannot eliminate it completely.

Why AI Ignores Instructions But Still Delivers Value

AI will continue to frustrate professionals who expect it to act like a person. It does not remember preferences, and it does not internalize instructions the way a colleague would. It operates through probabilities and defaults to patterns it has seen before. That explains why it sometimes drifts, even after you set clear rules. To get the best results, think of AI as something to create drafts rather than final products, at least for now. Repeat your directions, save the prompts that work, and expect adjustments. It is important to recognize why AI ignores instructions and approach it with curiosity, patience, and a willingness to guide it.
