Team stuck going in circles on a decision? Hand out 1,000 points of funny money and let everyone bet across the options. My 70-point bet vs. a teammate's 900 showed where conviction actually lived, more than hours of arguing did. ericmjl.github.io/blog/2026/9/...

Ask AI all day, remember nothing? That's cognitive debt. Answers aren't understanding. The fix is learning how to learn with AI as the accelerator, and one focused week is enough to acquire those skills. What would you learn first? ericmjl.github.io/blog/2026/8/... #learning #ai

Meta and X have been quietly downranking external links for ages, but we're now entering a new era of open hostility toward the open web. It's a great time to build your own website, free from any billionaires demanding a tithe for things that have always been free.

But, in many cases, whether measles, COVID, or climate change, bad science has serious negative consequences. In this case, it is the partial reversal of one of the great public health achievements of the last century. 🧪 #episky #medsky

Does AI widen the expert-novice gap? Live-demoed a Bayesian model with an agent. It amplified my judgment. For experts, a microscope. For novices, fast wrong answers. 'Vibe zones' and trust scaling with verification. What's your experience? #ai #datascience buff.ly/BVb49jC

At some point, you have to flip the switch from "it's dangerous to let everyone have this for offense" to "it's dangerous not to let everyone have this for defense." The jailbreak is credible but IMO the decision wasn't substantive. Anthropic created glasswing to prepare for this exact need.
