Most environmentalists have by now given up denying the existence of racial gaps in head size, but they only retreated a few yards: Nisbett, R. E., Aronson, J., Blair, C., Dickens, W., Flynn, J., Halpern, D. F., & Turkheimer, E. (2012). Intelligence: new findings and theoretical developments. American psychologist, 67(2), 130. Brain size and IQ. […]
notpoliticallycorrect.me/ Twitter: RaceRealist88 Since I am repeatedly asked by a bunch of differently looking people to comment on that particular blog. I don’t know the guy, but he’s been quite active in recent times. The blog is kinda odd in that it prominently features race realist stuff, a bunch of prominent race realist academics — […]
Skoyles, J. R. (1999). Human evolution expanded brains to increase expertise capacity, not IQ. Psycoloquy, 10(002). Chicago Skoyles is arguing a rather implausible claim: Why do modern humans have larger brains than earlier people such as Homo erectus? As large brains cause problems in childbirth, infancy and locomotion, the advantage they offer must be substantial. […]

I often read statistics textbooks. In textbooks, they often use example datasets, some of which are interesting in themselves (e.g. the Boston dataset). In this case, I am reading An Introduction to Applied Multivariate Analysis with R. It features a dataset of Egyptian skulls spanning about 4000 years. Given the scholarly interest in dysgenics and […]
Some readers may have fun reading this. I have not edited anything. Due to the conversion some extra lines were added, but his emails genuinely contains lots of oddly placed line breaks. The odd use of e.g. bold is his (Jayl is a male name, apparently). The topic of the email is “University of Toronto, […]

Updated 2015-12-04 Remains to be done: Admixture analysis (doing) Proofreading and editing Deciding how to control for age and scanner (technical question) Abstract I explore a large (N≈1000), open dataset of brain measurements and find a general factor of brain size (GBSF) that covers all […]
Seriously. Read it. Behavior Genetics (Impact Factor: 2.61). 03/2014; DOI: 10.1007/s10519-014-9646-x Source: PubMed ABSTRACT I argue that the g factor meets the fundamental criteria of a scientific construct more fully than any other conception of intelligence. I briefly discuss the evidence regarding the relationship of brain size to intelligence. A review of a large body of […]
