Remember, these are only tallies within his dataset. An example of how this matters is that there are more males at the top and bottom ends of IQ, leading to more Ts at the top and bottom. Likewise, there were substantially more older (and thus lower N/greater T/Lower IQ) subjects, etc.
So, a wide margin of error should be included when comparing it to the total population. (edit: Let me rephrase that... the generalities taken from this study should be given a wide margin of error when trying to be specific about the general population)
(One plausible explanation for having Ns as a higher IQ is that age factors into the degree of openness, and IQ decreases over age... making age the common factor that makes it appear that N is related directly to IQ. By plausible, I mean that there are alternative explanations... the data can be cut in a lot of ways.)
