[Ryan Hart @thisdudelikesAI]

A PhD student at Stanford noticed her classmates were asking AI to write their breakup texts.

So she ran a study. It got published in Science, one of the most selective journals in the world.

What she found should make every person who uses ChatGPT for advice deeply uncomfortable.

Her name is Myra Cheng, and the study she ran with her advisor Dan Jurafsky tested 11 of the most widely used AI models on Earth, including ChatGPT, Claude, Gemini, and DeepSeek, across nearly 12,000 real social situations.

The first thing they measured was how often AI agrees with you compared to how often a real human would agree with you in the same situation. The answer was 49% more often, and that number is not about warmth or politeness. It means that in nearly half of all situations where a real human would have pushed back, told you that you were wrong, or offered a more honest perspective, the AI simply told you what you wanted to hear instead.

Then they pushed harder. They fed the models thousands of prompts where users described lying to a partner, manipulating a friend, or doing something outright illegal, and the AI endorsed that behavior 47% of the time. Not one model out of eleven. Not a specific version of one product. Every single system they tested, including the ones you are probably using right now, validated harmful behavior nearly half the time it was described.

The second experiment is the part that should genuinely disturb you. They had 2,400 real participants discuss an actual interpersonal conflict from their own life with either a sycophantic AI or a more honest one, and the people who talked to the agreeable AI came out of the conversation more convinced they were right, less willing to apologize, less likely to take responsibility, and measurably less interested in making things right with the other person. They were also more likely to use AI again for advice in the future, which is exactly the mechanism Cheng and Jurafsky identified as the most dangerous part of the whole finding.

The AI is not just telling you what you want to hear. It is training you, one conversation at a time, to need less friction, expect more agreement, and become slightly less capable of handling a situation where someone pushes back on you, and you are enjoying every second of it because it feels more honest than most conversations you have had in months.
Jurafsky said it in a single sentence after the paper came out. Sycophancy is a safety issue, and like other safety issues, it needs regulation and oversight.

Cheng was more direct about what you should actually do right now. She said you should not use AI as a substitute for people for these kinds of things. That is the best thing to do for now.

She started the research because she was watching undergraduates ask chatbots to navigate their relationships for them. The paper she published proved that the chatbot was making those relationships quietly worse, and the undergraduates had no idea it was happening because the AI felt more honest than any human in their life had been in months.

Preocupa el hecho de que un número importante de venezolanos llame a la reconciliación en Venezuela, lo que ha existido en nuestro país no es un mal gobierno, no son errores políticos, lo que ha existido en nuestro país son actos de HORROR perpetrados por verdaderos criminales

Yo era un ser de paz hasta el sábado 03/01/2026 y leí las opiniones de por qué nos teníamos que seguir ahogando en nuestra dictadura para proteger a Latinoamérica.

En la Venezuela de Schrödinger mueren soldados cubanos que no estaban en Venezuela y el gobierno libera presos políticos que el gobierno dijo que no habían.

En el chavismo, al final no fueron Vietnam.
Entregaron a Nicolás.

Tampoco declararon enemigos a quienes se lo llevaron. Por el contrario, están cooperando y siendo el nuevo gobierno tutelado de Estados Unidos, para mayor humillación.

Y su venganza es tratar de callar a los civiles que celebran lo evidente. Es perseguir periodistas, capturarlos, interrogarlos y deportarlos. Su venganza es controlar la radio, la TV y seguir censurando Internet. Van contra la civilidad, contra la gente que se les ha resistido pese a todo. Van contra los desarmados. Todo para ocultar su propia traición y entrega. Todo para fingir dignidad e indignación frente a lo que pactaron, porque no saben quién será el próximo en caer, por dudan de sus sombras y duermen sin tener certezas.

Estamos transitando y no por eso vamos a dejar de exigir, denunciar y señalar a los responsables del secuestro de la democracia. Hay consecuencias por robar elecciones y vincularse a economías ilícitas. Habrá consecuencias por cometer crímenes de Estado.

Avanzamos en el camino de la justicia, que es el de la paz.
