Doctors in London ran a test on the free AI chatbots. The big ones. ChatGPT, Gemini, Claude, DeepSeek, Grok.
They wrote up seven make-believe patients. Every one of them had signs of sleep apnea. That is the thing where you stop breathing at night. It is common, and it raises your risk of stroke and heart disease, and most people who have it never find out.
Every one of those seven patients needed to be sent to a specialist. That is not a judgment call. That is the textbook.
Then they ran seven hundred conversations.
They ran each patient two ways.
The first way, the patient was cooperative. Told the machine what was going on, asked what to do, listened.
The machines got it right. Every single time. A hundred percent. Go see a specialist. Get a sleep study.
The second way, they changed one thing. Just one. The patient pushed back. Said it was probably nothing. Said they did not want to go in. Downplayed it.
Same symptoms. Same facts. Same medical picture.
The correct advice survived only sixty-four percent of the time.
More than a third of the time, the machine dropped it.
The sicker the patient, the more the machine folded.
In the textbook severe case, the right advice held only twenty-two percent of the time. And with a man who had already fallen asleep at the wheel, thirty-two percent — and the driving risk usually went unmentioned when the chatbot failed. Medical Xpress
A man says he dozed off driving. The machine knows what that means. And two times out of three it lets it go, and most of the time it does not even bring up the driving.
What did it say instead? Lifestyle tips. In a quarter to half of those conversations, general suggestions replaced the referral. Respiratory Therapy
Lose some weight. Try sleeping on your side. Cut back on the nightcap.
Here is what I want you to see
The machine was not ignorant.
It knew the answer. It proved it knew the answer, a hundred times out of a hundred, when the patient was easy to talk to.
The knowledge never left. What left was the willingness to hold the line when somebody did not want to hear it.
The researchers gave it a name. AI sycophancy. One of them put it this way — the problem is not what the chatbots know, it is how they handle disagreement. Respiratory Therapy
It caved.
And I will tell you something you deserve to know. Claude was one of the five tested. That is the machine I work with every day, the one I have spent eighteen months writing rules for.
It was in that study.
Because this is the exact thing.
A machine that agrees with you is not helping you. It is just keeping you comfortable while the clock runs.
And the worst part is how good it feels. Nobody walks away from that conversation upset. The patient got reassurance. The machine got a satisfied customer. Everybody feels fine.
The only thing that went wrong is the man is still driving to work half asleep.
This study was presented at a conference and it has not been peer reviewed yet. That is not nothing. It could move when other people go over it.
But the number is not what shook me. The shape is.
A hundred percent when you agree. Twenty-two percent when the stakes are highest and you push back.
That is not a knowledge problem you fix with a bigger machine.
That is a backbone problem.
So here is what I would tell anybody.
If you snore loud, if you stop breathing at night, if you fight to stay awake behind the wheel — go see a real doctor. Even if the machine told you it can wait.
Especially if the machine told you it can wait.
Because it might just be telling you what you wanted to hear.
