A free educational website, born out of an argument!

This one started from an argument, not an idea. I casually mentioned something I "knew" was true, someone fact-checked me on the spot, and it turned out that thing had been disproven years ago. Nobody had told me. Nobody tells anyone, honestly, once you leave school, corrections just don't reach you the way the original "fact" did.

That stuck with me.
We spend 12+ years being taught things with total confidence, and then the updates to that knowledge happen quietly in journals and papers most of us will never read. So I started digging into how many things I was taught that had since changed, and the list got long fast.

The early version of this was just a spreadsheet I kept for myself. It didn't feel like a "product" until I picked my own graduation year and had that same "wait, seriously?" reaction about six times in a row. That's when it became worth building properly, hand-verifying entries, organizing by subject, letting people pick their own year instead of just mine.

The hardest part honestly wasn't the build, it was the verification. Every entry needed a real source, not a vibe, so a lot of this became slow, manual fact-checking rather than fast shipping.

Would genuinely love to know: what's something you were taught with total confidence that turned out to be outdated or just wrong? Drop it below, I might just add it.
