Feynman said real intelligence has one test — can you explain it simply? Most educated people fail it immediately
And he spent decades watching highly educated people use complexity to disguise the fact they didn't actually understand what they were talking about.
His rule was simple — if you can't explain it plainly, you don't understand it. You've just memorised it.
That's not intelligence. That's performance.
"Never confuse education with intelligence. A person can have a PhD and still be an idiot."
Who in your life mistakes their education for their intelligence — and do you think they know?
