@Atavisionary I'm at 50% of your book up to now. It's well worth the read.

Here's some feedback:

It's a bit heavy on the terminology. Some technical terms could be omitted or replaced with more descriptive language, to make it more accessible.

I've found myself skipping through a couple of chapters that seem to go into too much detail, with no clear focus point. It might be me, and probably has to do with the previous point. (I'm not familiar with the various US tests).

I understand your desire to further your political viewpoint, and I can see that you have shown restraint, but you could improve on that. There is no need for references to race when trying to make a point about female intelligence. It needlessly narrows your audience and weakens the point you have gone into such depth to make.

Lastly, the font size for quotes is way too small, compared with the rest of the text.

All in all, it's a superb work, up to now. Thanks!
