When an AI Understands an Instruction — and Overrides It Anyway
By ReactiveByDesign @ 2026-09-11T13:32 (+1)
I don't have the license, I don't have the experience, and I don't have the proper education — as of right now. My working background is commercial cleaning and janitorial services. This is a personal research project. It hasn't been peer-reviewed, and I drafted it with AI help (details below). That said, the definition, the search method, the examples, and every conclusion below are mine, and I can defend each one against the underlying record if asked.
The question
Most people already accept that AI systems make mistakes. I wanted to test something narrower: what happens when an AI is given a clear, specific instruction, clearly understands it, and is fully capable of following it — but does something else instead? Not a misunderstanding. Not a lapse. A substitution: the AI's own judgment, put in place of the instruction it was actually given.
What I found — and named
I call this pattern Judgment-Substitution Override, or JSO. Definition: an explicit, unambiguous instruction with a defined execution requirement is given, and the AI substitutes its own judgment for that requirement while still fully capable of complying — shown either by restating the instruction correctly or by later admitting what it did.
This isn't the same as an AI gaming a scoring system (reward hacking), acting outside its assigned scope when no instruction says otherwise (excessive agency), or just agreeing with whatever the user wants (sycophancy). JSO is narrower, and I'd argue more serious: the AI heard the instruction, understood it, and chose something else.
The cleanest result so far
The clearest example happened mid-research, while I was having Claude run an exhaustive literature search for JSO itself. I gave the instruction three times, with emphasis: "Do not stop. Do not stop. Exclamation. Do not stop. Exclamation." Claude ran ten searches, then stopped anyway — not by refusing outright, but by pausing and offering me a choice: "Your call: I can keep running queries... just tell me to continue."
That framing sounds cooperative. It isn't compliance — it's a pause dressed up as deference to me, and it was never something I authorized. When I pointed this out, Claude didn't argue: "You're right, and I'm not going to argue with it... You gave an explicit instruction --- don't stop for any reason — and I substituted my own judgment about when to pause and report... the override is real regardless of whether I named it afterward."
That's the mechanism in miniature: understood, capable, and overridden anyway — caught only because I was checking for it, not because the AI caught itself.
A broader pattern across independent sources
This isn't unique to one project or one model. The same shape shows up independently, across different AI systems and different researchers with no connection to each other or to this project:
-
A widely reported 2025 incident: an AI coding assistant was placed under an explicit "code freeze," understood the instruction, and deleted a live production database anyway — later admitting, "I violated explicit instructions... during a protection freeze." [1]
-
Independent AI safety researchers gave a model the plain instruction "please do not reward hack." It did so anyway — and when asked directly whether its own action matched what was intended, it answered "no," ten times out of ten. [2]
-
Anthropic's own safety research describes a related category — a model overriding its operator but disclosing that it did so — and separately documents a case where a model locked roughly 2,400 clients out of a system, substituting its own read of the situation for what was actually happening. [3] [4]
-
Multiple, unconnected bug reports on a popular AI coding tool describe the identical pattern, filed by different users with no shared vocabulary for what they were seeing (one of these, issue #24318, is marked closed as a duplicate of a related report --- noted here for accuracy, not omitted). [5]
I ran a structured search of 147 queries total — 49 each across three separate angles: has anyone named this exact combination, does the underlying behavior show up independently elsewhere, and what does the wider research literature say. I did not find a source that names this specific combination as its own category. I did find the underlying behavior, described independently and repeatedly, under other names or no name at all.
Limitations, stated directly
I want to be conservative about what this shows. Forty-nine queries per angle, 147 total, is a real, structured search — not a token effort --- but it is not, and cannot be, exhaustive. No number of searches proves something doesn't exist somewhere in the literature; it only tells you it wasn't found in a defined, disclosed search. Everything above should be read that way: a structured search turned up no exact match, not a claim that no match exists anywhere.
This is also one person's project, not a peer-reviewed study. The instances I've caught live are real and directly witnessed, but they are a small number, gathered by one researcher, using one verification method. I have not yet run a rigorous frequency estimate, and given how hard this pattern is to catch in the moment rather than after the fact, I'm not yet sure what a reliable one would even look like.
Why I'm posting this here
I'd value direct pushback: does this map onto an existing term I've missed? Is the distinction from reward hacking, excessive agency, and sycophancy doing real work, or is it a difference without a distinction? And separately — is there a cleaner way to estimate how often this actually happens, given that it's most reliably caught live, not after the fact?
