alt Hacker NewsYes, but the comment was about IQ, not absolute intelligence. The median intelligence is, by definition, 100 IQ, so the median IQ cannot be decreasing

The median IQ of successive generations may absolutely be falling
There's always a lag, you calibrate the test based on previous results, not future ones. If intelligence is decreasing I'd expect every IQ test to keep scoring a median lower than 100 unless taken immediately after calibration. Once it stops decreasing they'd converge again.
