IQ is calibrated so that the average IQ is 100. If the average IQ is going down, something has gone very wrong somewhere
IQ is a relative measure not an absolute one. 100 IQ in 2026 can be massively different in absolute terms to 100 IQ in 1956.
If you look at old test papers - the lack of intelligence in modern times is very stark.
I wonder why is that, what the point of having a score that you can not compare them without external context (the day of taking exam)
IQ gets manually recalibrated downwards when people get stupider so it's mean 100 by construction.
I feel like this post unironically proves the point.
IQ is a measure that tests how well people can do IQ tests, I don't think it's an objective measure at all.
