AI doesn't look like robots in 2026. It looks like autocorrect that's gotten weirdly good, search that quietly reads your context, and a thousand small product decisions you barely notice. Here's what's actually under the hood, from someone who's shipped these features.
Your feed isn't neutral, but it's also not the simple villain in most articles about it. Here's what the systems actually do, from someone who's read the papers and built smaller versions of them.
Most articles about 'AI safety' are about long-term risks researchers think about at conferences. This one is about the small, near-term mistakes regular people are actually making — and how to avoid them.
Your memory does not store experiences in equal weight — peaks and endings dominate everything else. The classic colonoscopy study that proved it is genuinely strange, and the implications change how you should design meetings, workouts, and trips.
Most new habits fail not because of laziness but because they have no reliable cue. Habit stacking — borrowed from BJ Fogg's tiny habits work and popularized by James Clear — fixes the cue problem by attaching the new behavior to one you already do.
Cameron Anderson at Berkeley showed in a clean experiment that overconfident people get rated as more competent — even when they're objectively wrong. Here's what that means for meetings, news, and how to push back against persuasive certainty.
Wearing an embarrassing T-shirt, Thomas Gilovich's lab showed that people dramatically overestimate how much strangers notice them. The spotlight effect is real, well-replicated, and surprisingly useful to understand.
Your brain is about 2% of your body weight but uses around 20% of your daily energy — and most of that runs in the background, whether you're solving a hard problem or just staring at the wall.
It is one of the strangest findings in modern medicine: a sugar pill, openly labeled 'placebo,' still helps real patients. Here is what the studies actually show — and what they do not.
You have probably heard the 'magic number seven' for working memory. It's a famous result from 1956 — and the newer research has quietly revised it downward.
Neuroplasticity is real, well-studied, and quietly misrepresented by half the books written about it. Here's what the actual research shows — and where the optimistic version oversells.
Honey found sealed in 3,000-year-old Egyptian tombs has been chemically intact and theoretically edible. The reason has nothing to do with magic — it's three boring chemistry properties stacked on top of each other in a way no microbe can deal with.
Octopuses have three hearts and blue, copper-based blood — and the main heart actually stops beating when they swim. Here is why their biology took such a different path from ours.
Every banana you eat is mildly radioactive — and so is your own body. Here is what the 'banana equivalent dose' actually means, why physicists invented it, and why it does not work the way you would expect.
The famous 'hungry judges' study has been everywhere — but the follow-up research is much messier than the headline. Here is what decision fatigue research actually shows and what to do about it.
