Growing up, I knew a few things about dinosaurs. Like a lot of things I learned as a child, I accepted them and moved on, never bothering to question them.
Recently, I learned:
- Birds are dinosaurs.
- Spinosaurus is better than Tyrannosaurus.1
- Brontosaurus was once considered its own genus, then it was just an Apatosaurus, then it was different again.
It turns out there was a time2 when it was declared the Brontosaurus didn’t exist. (Because it was the same as the Apatosaurus, the paleontologists said.) And then there was a big announcement that it actually did.
We’ve all learned things as children that we’ve carried into adulthood. Most are probably true and harmless, but a lot aren’t.
What “truths” about jiu-jitsu did you learn as a white belt and still believe, years into your training?
