Never cut what you cannot name

Wharton’s latest AI study points to a hard truth: “AI writes, humans review” model is breaking down Why "just review the AI output" doesn't work anymore, our brains literally give up. We have started doing "Cognitive Surrender" to AI - Wharton’s latest AI study points to a hard truth: reviewing AI output is not a reliable safeguard when cognition itself starts to defer to the machine.when you stop verifying what the AI tells you, and you don't even realize you stopped. It's different from offloading, like using a calculator. With offloading you know the tool did the work. With surrender, your brain recodes the AI's answer as YOUR judgment. You genuinely believe you thought it through yourself. Says AI is becoming a 3rd thinking system, and people often trust it too easily. You know Kahneman's System 1 (fast intuition) and System 2 (slow analysis)? They're saying AI is now System 3, an external cognitive system that operates outside your brain. And when you use it enough, something happens that they call Cognitive Surrender. Cognitive surrender is trickier: AI gives an answer, you stop really questioning it, and your brain starts treating that output as your own conclusion. It does not feel outsourced. It feels self-generated. The data makes it hard to brush off. Across 3 preregistered studies with 1,372 participants and 9,593 trials, people turned to AI on over 50% of questions. In Study 1, when AI was correct, people followed it 92.7% of the time. When it was wrong, they still followed it 79.8% of the time. Without AI, baseline accuracy was 45.8%. With correct AI, it jumped to 71.0%. With incorrect AI, it dropped to 31.5%, worse than having no AI. Access to AI also boosted confidence by 11.7 percentage points, even when the answers were wrong. Human review is supposed to be the safety net. But this research suggests the safety net has a hole in it: people do not just miss bad AI output; they become more confident in it. Time pressure did not eliminate the effect. Incentives and feedback reduced it but did not remove it. And the people most resistant tended to score higher on fluid intelligence and need for cognition. That makes this feel less like a laziness problem and more like a cognitive architecture problem.

Pay attention folks!!!!

Nos dicen que estamos cansados por hacer demasiado. Pero tal vez el agotamiento venga de lo que hemos dejado de hacer: imaginar, contemplar, detenernos. La fatiga no es solo laboral; es existencial, estructural, una fractura silenciosa. @Aspirar_al_uno ethic.es/la-desaparicio…

Our PERFECT trial finally out in @TheLancet ! Pragmatic Nordic 🇫🇮🇳🇴 multicenter RCT comparing appendectomy within 24h versus 8h. 1803 patients! No difference in rate of perforated appendicitis (9% vs 8%). 👉 Allows to postpone appendectomy to daytime. authors.elsevier.com/a/1hluDV-4XL3R-

Quienes critican a los aspirantes por una calificación y los comparan con años anteriores deberían leer sobre percentiles. En un examen de dificultad variable por año, no importa la calificación sino el desempeño respecto a generación. En todo caso comparen percentiles por año.

En este ENARM fui el niño del triciclo.

Así se sentía cuando empezabas a hacer ciencia 🤣🤣🤣

Desde 2020, 10 médicas, médicos y pasantes han sido asesinados. Su comunidad, a la que se unieron estudiantes de medicina, marchó para exigir seguridad y condiciones dignas. Los detalles en #Hora21 con @genarolozano | #SiempreEnVivo | #SiempreContigo

Acabas de ordenar una pizza con orilla de queso, tienes tu cassette de Diddy Kong Racing 64 y un gansito esperándote en el congelador. No hay clases mañana, tienes permiso de tus papás para desvelarte. Tienes 39 años, el año es 2022.

Los médicos deberían de hacer el servicio social en investigación. Le harían un bien al país y a ellos mismos. Oportunidad de oro para conocer el pilar de la medicina al que casi ninguno se acerca durante la carrera.

A mí sí me da apendicitis si operenme luego luego no le hagan a la mamada que manejo conservador y eso

Tip Gastro 👨🏻‍⚕️ Según la GPC el AINE con mayor riesgo gastrolesivo es el Ketorolaco (RR 14.1), luego Naproxeno (RR 4.2), luego Ibuprofeno (RR 3.9) y luego el Diclofenaco (RR 1.8) 🧐💊 #ENARM
