If your claim is that the book you have recommended ... is the last word on the subject That would be an audacious claim, considering the book is rather old and only 200 pages. I recommend it because it is a model of concise and accessib

I have not read Stanovich's book but it does not appear to be an appropriate introduction to the subject of intelligence. I suspect you recommend these "newer and better" books because they suit your ideological purposes, not because they

There is a lot of data on this question, and it flatly contradicts Asimov's claims. IQ scores correlate not only with academic performance but also with job performance as well as others' intuitive impression of how "smart" a person is. T

The combination of IQ and "chutzpah" is the essence of the entrepreneurial personality. If Jews are (for whatever reason) disposed to be high on these traits, it's certainly a sufficient explanation.

It's pretty simple. People who think in personal, emotional terms tend to explain the world that way, while people who think more logically/mechanically explain the world that way. That's where religion and science, respectively, come fro

No one has proved that technology won't one day make everyone grow to 6 feet and live 200 years. In fact that could quite plausibly happen. But you'd still be a fool to count on it.

Course catalogs tell you nothing. They're stuffed with appealing descriptions of courses which may or may not end up on the schedule, and when they do, may or may not resemble the description in the catalog. Not to mention the teachers' k

If you want to learn, then going to a Respected Research University is a waste of time and money. The quality of teaching at such places is often pathetically bad. Prestige comes from research, not teaching, and every dollar spent on rese

Zero is not defined to be even. A number is even if it's twice some integer. Zero is twice an integer (namely 0), so it's even. If you try to bring personal intuition into mathematics, you'll just repeatedly shoot yourself in the foot I

Haskell does well in benchmarks but this hides the fact that its performance is very unpredictable. Try it and you'll see what I mean. Also, Common Lisp does well in benchmarks but only after a lot of declarations are added which make the

Body size varies more within dog breeds than between them I have never understood what this means. "Within-group" variation can be quantified as standard deviation (among other metrics). How do you measure "between-group" variation? Sa

True, but in this case, the template serves a different purpose from the macro. It's there to make zap polymorphic, and would be unnecessary in a dynamic or type-inferred language. The main point is that pg's macro can be implemented as

C++ version: template<typename T> void zap (T (*f)(T x), T &x) { x = f(x); } Example: int square (int x) { return x*x; } int foo[5] = {1,2,3,4,5}; zap<int>(square, foo[3]); // foo is now {1,2,3,16,5}

So how is rationality defined and how is it measured? Does it correlate with any important life outcomes such as income, academic performance or law-abidingness? He says that irrationality can be "fixed." Does this fix result in measurab
