Having already been commented upon by several reviewers, the paper's analysis seems pretty comprehensive at this point. In addition, the paper reads relatively well; there is no need for any major grammatical or stylistic changes. However, I would ask Emil to address the following points, following which I believe the paper will be ready for publication.

1. Table 1 would be easier for the reader to interpret if the variables were ordered by strength of correlation (from largest negative to largest positive, say).

2. Analogous to Emil's finding that many of the correlations between S variables and cognitive ability became more sensical after conditioning on population density, Lynn (1979) reported a positive correlation between IQ and crime rates across regions of the British Isles, which then fell to zero when conditioning on urbanisation. He noted:

"The positive correlation between crimes rates and mean population IQ (r = + 0.51) is surprising in view of the many findings of a negative relation among individuals... When urbanization is partialled out the correlation between crime rates and mean population IQ drops to zero. Perhaps this is the true relationship between crime and intelligence."

Perhaps Emil would like to mention this.

3. Underneath Figure 7, Emit notes, "Okinawa is an outlier, but it is reasonably close to the regression line”. However, eyeballing the graph suggests to me that Okinawa may not only be an outlier, but also an influential point––at least to some extent. It would be worth reporting the correlation with and without Okinawa included in the sample.
