Intelligence, neo-liberalism/socialism and sex.

Assumptions:

1. There is a positive correlation between neo-liberalism and intelligence.

Strongly Favor Wage Laws: 5.17 Wordsum
In Favor: 5.71 Wordsum
Neither: 5.80 Wordsum
Against: 6.45 Wordsum
Strongly Against: 6.88 Wordsum

2. Females are more likely to be socialists than males.

27 % Males favor Wage Laws, 28 % Females.
19 % Males do not have a position, 25 % Females.
54 % Males against Wage laws, 47 % Females.

3. Male intelligence and female intelligence is very similar.

WORDSUM: 5.94 For Males
WORDSUM: 6.03 For Females

(WORDSUM is a test of verbal intelligence)

Inevitable Outcome:

Male socialists will be less intelligent than female socialists.
Male capitalists will be less intelligent than female capitalists.

Even if we take in account the 0.07 WORDSUM difference.

There might be exceptions in specific categories, but if we take fewer groups (by taking categories together) the relationship will hold.

Results:

WORDSUM, by sex and economic position:

At least in Favor of Wage Control 5.46 (Males), 5.62 (Females)
No Position 5.68 (Males), 5.87 (Females)
At least against Wage Control 6.52 (Males), 6.63 (Females)

This wasn't very important, just a little funny statistical effect.

Results probably would be similar if I also looked at price control instead of wage control.

Most neo-liberal variables are correlated with intelligence, with the exception of scientific research subsidiaries.

This is the result of a political survey taken by an high IQ group:

Here is a bold prediction:

Males who did not complete college are smarter than females who did not complete college.
Males with a college diploma are smarter than females with a college diploma.

Cognitive decline in modern america


This table give various values of WORDSUM (a test of verbal ability)

and their relation to:

The number of children per adult (over 35 years old). (Trend line)
The age at the birth of the first child. (Trend line)
Current and future % of population (See important note on heritability)

Also, the current mean wordsum is 5.99 but will decline by 0.22 Wordsum* Heritability(Wordsum) in 25 years and by 0.44 Wordsum*Heritability (Wordsum) in 50 years.

I use this age as a generation length (incorrectly, but it should be only a marginal error that doesn't change the main point)
I can compute by how much each given group will increase, and the likely population over numerous years.

Note:

The raw difference in cognitive decline need to be multiplied by the heritability of WORDSUM, which is not known. (A fair guess might be 0.6 to 0.8)

(Do not consider the future group with a wordsum value of 4 to actually obtain a value of 4, I only use the data this way because it is more easy) Don't forget that little regression to the mean concept.
