I'm not sure what those Q1-Q4 numbers are, but I don't think they are quartiles. I went to a TIP ceremony for kids who'd scored well on the SATs in 7th grade. There were a few hundred kids there (I think something like 1000 got you there?), a few dozen with 1200 something, and one kid up on stage with a 1400.

Step 2: Sort these highly able kids into quartiles by their test scores. Result: Even within the top 1% of IQ, the relative ability still matters. I.e. there is no "cutoff" for becoming a great scientist or inventor; smarter is always better.
