My typo, I meant Galton.
What is its scope today? (I answered hitssquad before I saw your post; I'm quite curious as to the boundaries - e.g. is it psychometrics when my doctor uses an electronic stopwatch and ruler to measure my knee reflexes? since taste is subjective - and mental - and can be measured quantitatively I'm sure, is the study of taste a branch of psychometrics?)
I'll see if my local library has a copy. Why is it called 'Intelligence'? From the definition, it would seem that intelligence would be a very small part of the field.
I'd've thought that, since you're working with humans and their mental states, double blind protocols would be even more important in psychometrics than in studies of glucose uptake! Surely the psychometric equivalent of the placebo effect (or the 'white coat effect') would be huge
Wow! That's truly staggering!! After all, plenty of studies have shown that there are quite significant physiological differences between first generation migrants and their stay-at-home peers, esp the effects of diet (e.g. incidence of heart disease, the switching on - or off - of various enzyme reaction trigger genes, and much more). Too, IIRC, the effects of the childhood environment and pre-birth environments can be enormous - just look at the crack babies, and the well-known 'siblings' effects. The findings you just reported would seem, prima facie, to fly in the face of a vast amount of medical research.
My comment was based on my assumption that it was a completely new field; in any new field, there is a period in which critics - rightly - question whether it is really a science. Look at astrobiology, for example.
Hmm, do you mean in the last ten years? The link which Evo posted has some pretty weighty pronouncements, e.g. "What is intelligence and can it be measured? These questions have fueled a continuing debate about whether intelligence is inherited, acquired, environmental, or a combination of these and other factors. In a field where so many issues are unresolved and so many questions unanswered, the confident tone that has characterized most of the debate on these topics is clearly out of place.
" Of course, this is in reference to the bell curve, and was written in 1995. The 1996 letter to Science by the members of the HGP was also pretty damning - surely they're not crackpots?
Is there now a biological theory of intelligence? Or are there competing theories?
What are 'chronometric measurements'? What is the typical experimental error in _g_ from these? Ditto, for EEG measurements? How are the 'zero point' and scale of _g_ defined?
