Who Invented the IQ Test?
I was about to take an IQ test when I randomly started wondering where the whole idea came from. I knew IQ was supposed to measure things like reasoning and problem-solving, but I never really thought about who came up with it.
Turns out the history goes back to the early 1900s, and the original purpose wasn't quite what I expected.
It actually made me more curious about how today's IQ tests compare with the original ones.
