IQ scores show extreme subnormal intellectual ability. Scores above that (including the majority of below average scores) tell us precisely nothing. Zero. Nada. Nowt.
Consider this research again in that light maybe?
The IQ score research fraud needs to be called, loudly, by all of us every single time some charlatan uses it.
What you are saying isn’t accurate… IQ tests are reliably repeatable, and accurately predict ability at a large number of other tasks. There was a pretty good recent radiolab podcast talking about the history and evidence behind it.

That's just not true. Among other things, they quite reliably predict how well you will do on an IQ test 10 years from now. This might sound trivial, but it's a good indicator that they are:
1. Measuring something
2. Measuring something that is intrinsic, in the sense of it being stable over time.
I thought they made experiments on kids who recently moved in another country that show that IQ isn't stable in kids and depends on the environment?
There are environmental effects. Common sense things can affect performance on IQ tests, including taking the test a second time in short succession (you get better with practice). Certain early childhood education interventions will cause children to over-perform on IQ tests relative to their IQ measured later in life. If the subject has the flu, they will also tend to underperform. The environment definitely plays a role, but the degree to which it is stable is, to me at least, surprising.
