Reply To: How important are brains?

Haleivi, would you say it is more or less important as comparative intelligence increases? Or possibly it depends whether you fall in the middle or the edges of the curve on either side? I could see 10 IQ points making a big difference, if you’re going from 80-90. I could also see it if you’re going from 120-130. But does it really matter if you are 95 or 105?*

The counterargument is that in absolute terms, you surpass more people if you are in the middle of the pack and you gain ten points. Whereas if you go from 120-130, then you gained only a couple percentiles.

*For purposes of this post, assume 100 is the mean and median, although Ashkenazi Jews have a higher average. I wrote it this way to indulge the assumption of a normal distribution, and also so as not to exclude Sefardim.
