Intelligence: All That Matters
There is a strange disconnect between the scientific consensus and the public mind on intelligence testing. Just mention IQ testing in polite company, and you'll sternly be informed that IQ tests don't measure anything "real", and only reflect how good you are at doing IQ tests; that they ignore important traits like "emotional intelligence" and "multiple intelligences"; a...more
In this other universe, most things are just as they are in ours. Humans themselves are no different. But the other universe differs from ours in one respect -- the way that its scientists conceive of physical fitness.
In our universe, we know -- in a casual, non-scientific (if not unscientific) way -- that there is such a thing as physical fitness. Some people are more fit than others. We recognize different levels of fitness, and refer to ...more

Is the g theory of intelligence the most mature, replicated theory in psychology? 100 years old and ever-replicating; language- and culture-blind by now; at least somewhat predictive of some terminal values... What can compete? Operant conditioning, I guess.
This book is part of the "All that Matters" series - a coincidental subtitle which has no doubt enraged many people and caused him no end of grief.

I talk down a lot of books for being much longer than they needed to be so it's only fair that I mention this book is exactly as long as it needs to be, it's been shrunk down to a little nugget of knowledge you can read in an afternoon. ...more
I thought the author did a good job of summarizing what we know carefully and expl ...more
So, first, about that subtitle: at no point does the book ...more
Ritchie understandably skips over the toxic and scandal-prone area of intelligence differences between groups.
I'm not a cognitive psychology scholar, but Ritchie seems to make another important omission for an introductory book. Namely, when discussing the effects of education, he fails to address the issue of im ...more
For anyone interested in the importance of IQ-- this is the best place to start. For anyone looking for more in-depth or obscure information on IQ, look elsewhere. This is an introduction, not a deep dive. He ha ...more
In the 1960s, the Norwegian government (p 92) decided to add two extra years to the mandatory curriculum for all pupils.Two additional pieces of good luck allowed researches, who came on the scene much later, to turn this into a test of the effects of schooling on IQ.
First, the reform was implemented across the different parts of Norway in a staggered way – it happened in some areas year ...more
Recalling my own experience as a grade schooler the fact that some of my fellow classmates handedly outperform me on various tasks is intuitive and uncontroversial (if not frustrating). That pre-political mind of mine seemed to have no issue recognizing differences in abilities.
I've come across some criticism of intelligence research over the last few years. A generalizable feature o ...more
Some subjects were kind of glossed over near the end, but that might just have been to keep the book within a certain scope as an in ...more
But one (tiny) mistake:
"the parietal and frontal areas need to send information between one another. To do that, they rely on another kind of brain tissue, the white matter”. White matter cells – so-called because of the white-coloured insulation material, myelin, that surrounds their long, tendril-like axons".
Nope. White matter cells don't exist. Any cell is grey matter. White matter refers only to the axons. ...more
