I mean, technically, height is not like height either.
One's height is not fixed, even in a given day.
But I get his point. Kind of.
Intelligence is more like speed. Speed can be affected by multiple things. Once you run X fast, it doesn't mean you'll always be able to run that fast. One's top speed is more of a range than a fixed point.
And we measure speed all day long.
Intelligence is a thing. People have it to different degrees. People often mistake it for knowledge. And IQ is a way to measure at least a part of it.
