But what the hey:

1) Overall brain size (in non-pathological cases) is a terrible measure for just about any ability you can think of especially something as complex as "intelligence"

2) Even throwing that idea out, overall brain size is highly influenced by epigenetic factors such as nutrition, enrichment, etc.

3) Throwing that out, many of the measurement studies on overall brain sizes and race are confounded by (off the top of my head - there's more) a) selection bias, b) statistical problems such as the "regression effect", and c) the problems of grouping into races (perhaps an offshoot of a?), and d)problems in using traditional IQ tests.
