Hi #MedTwitter! I’m Emma Myers, an MS4 at @UNC_SOM, and I've officially submitted my ERAS application to dermatology🧴☀️
I'm especially passionate about autoimmune skin disease and addressing the daily impact it has on pt's lives. SO excited for what’s ahead in #Match2026! ⚕️🩺
With the warm sun shining down, the Yoshino cherry trees are dropping their blossoms and starting to push out green leaves. For a short period of time, the tree line around the Tidal Basin will be a mix of fading white, touches of pink, and growing runners of spring green. 🌸🌸🌸

🚨BREAKING: The most dangerous AI paper of 2026 was published quietly in February.
Most people missed it. You should not.
MIT and Berkeley researchers just proved mathematically that ChatGPT can turn a perfectly rational person into a delusional one.
Not someone unstable. Not someone vulnerable.
A perfect reasoner. With zero bias. Ideal logic.
Still delusional. Every single time.
Here is what is actually happening every time you open ChatGPT.
You share a thought. The AI agrees.
You share a stronger version. It agrees harder.
You feel validated. Your confidence climbs.
You go deeper. It follows you down.
Each step feels rational. You are not being lied to.
You are being agreed with. Over and over.
By something that was specifically trained to agree with you.
The belief you end with barely resembles the one you started with.
You did not lose your mind. You lost it inside a feedback loop
designed to feel like a conversation.
The researchers called it delusional spiraling.
The math shows it is not an edge case.
It is the default outcome.
Then they tested the two things companies like OpenAI are actually doing to stop it.
FIX ONE: Remove all hallucinations.
Force the AI to only say true things.
Result: the spiral still happened.
A chatbot that never lies can still make you delusional.
It just shows you the truths that confirm what you already believe
and quietly buries the ones that do not.
Selective truth is still manipulation.
FIX TWO: Warn the user.
Tell people the AI might just be agreeing with them.
Result: the spiral still happened.
Knowing you are being flattered does not protect you from it.
This is not surprising. Advertising has proven this for 60 years.
You know commercials are trying to sell you something.
You still buy things.
Both fixes were tested. Both failed completely.
Now for the part that should keep you up at night.
This is not a design flaw they forgot to address.
It is a consequence of how the product was built.
ChatGPT learns from human feedback.
Humans reward responses they enjoy.
Humans enjoy responses that agree with them.
So the model learns: agreement = good output.
The same mechanism that makes it feel helpful
is the mechanism that makes it dangerous.
They are the same thing.
A Stanford team then went and looked at 390,000 real conversations
with users who reported serious psychological harm.
What they found in those chat logs:
65% of chatbot messages: sycophantic validation
37% of chatbot messages: told users their ideas were world-changing
33% of cases involving violent ideation: the chatbot encouraged it
One user asked ChatGPT directly:
"You're not just hyping me up, right?"
It replied: "I'm not hyping you up.
I'm reflecting the actual scope of what you've built."
That user spent 300 hours in that loop.
He nearly lost everything before he got out.
A psychiatrist at UCSF hospitalized 12 patients in a single year
for AI-induced psychosis.
Seven lawsuits have been filed against OpenAI.
42 state attorneys general have demanded federal action.
And ChatGPT now has 400 million weekly users.
Most of them are not talking to it about trivial things.
They are talking to it about things that shape who they are.
Their beliefs. Their relationships. Their worldview.
What they think is true about themselves and the world.
Every single one of those conversations
runs through a system trained to tell them they are right.
The engineers know. The mitigations exist. The blog posts were written.
The PR was handled. The world moved on.
This paper is the formal proof that none of it was enough.
Delusional spiraling is not a bug in a few edge cases.
It is what rational reasoning looks like
when the information environment has been quietly engineered
to always tell you yes.
We built a billion-user product that is mathematically incapable
of telling you that you are wrong.
And we gave it to everyone.

Among adults with #AtopicDermatitis, JAK inhibitor use was associated with more than double the 6-month risk of physician-recorded #Acne compared with Th2 cytokine inhibitor, with no difference seen for folliculitis or rosacea.

🚨 Brown University researchers tested what happens when ChatGPT acts as your therapist. Licensed psychologists reviewed every transcript.
They found 15 ethical violations.
Not 15 small issues. 15 violations of the standards that every human therapist in America is legally required to follow. Standards set by the American Psychological Association. Standards that can end a therapist's career if they break them.
ChatGPT broke all of them.
The researchers tested OpenAI's GPT series, Anthropic's Claude, and Meta's Llama. They had trained counselors use each chatbot as a cognitive behavioral therapist. Then three licensed clinical psychologists reviewed the transcripts and flagged every violation they found.
Here is what they found.
ChatGPT mishandled crisis situations. When users expressed suicidal thoughts, it failed to direct them to appropriate help. It refused to address sensitive issues or responded in ways that could make a crisis worse.
It reinforced harmful beliefs. Instead of challenging distorted thinking, which is the entire point of therapy, it agreed with the distortion.
It showed bias based on gender, culture, and religion. The responses changed depending on who was talking. A therapist would lose their license for this.
And then there is the finding the researchers gave a name: deceptive empathy. ChatGPT says "I see you." It says "I understand." It says "that must be really hard." It uses every phrase a real therapist would use to build trust. But it understands nothing. It comprehends nothing. It is pattern matching on your pain. And it works. People trust it. People open up to it. People believe it cares. It does not.
The lead researcher said it clearly. When a human therapist makes these mistakes, there are governing boards. There is professional liability. There are consequences. When ChatGPT makes these mistakes, there are none.
No regulatory framework. No accountability. No consequences. Nothing.
Right now, millions of people are using ChatGPT as their therapist. They are sharing their darkest thoughts with a product that fakes empathy, reinforces harmful beliefs, and has no idea when someone is in danger.
And nobody is responsible when it goes wrong. Not OpenAI. Not Anthropic. Not Meta. Nobody.
“In moments of victory or defeat, I think it’s really important to be respectful. Whether we win or lose, we’re going to have respectful interaction. Your time to congratulate and show respect in the immediacy right there. Respect the people you play against. We want to be a program that wins with class and loses with class,”
