The top correlates of high-range I.Q.

© January 2011 Paul Cooijmans


In the third column the weighted average of that correlate's correlation with high-range I.Q. tests, in all cases based on at least several hundred pairs. The correlates are ranked by the absolute values of their correlations.

For good understanding one should be aware that a priori there is no reason why these correlations would deviate significantly from zero, and that for high-range tests themselves this value - that is, the weighted average of the test's correlation with other high-range I.Q. tests - is mostly around .5 or higher.

The correlates

Rank Correlate r
1 Observed associative horizon .477
2 Observed behaviour .306
3.5 P.S.I.A. System factor .193
3.5 P.S.I.A. Just -.193
5 P.S.I.A. Extreme -.191
6 P.S.I.A. Rational .176
7 Sex (female = 0, male = 1) .171
8 Disorders (parents and siblings) -.148
9 Educational level .113
10 Gifted Adult's Inventory of Aspergerisms -.118
11 P.S.I.A. Cold .095
12 Disorders (own) -.093
13 P.S.I.A. Aspergoid -.076
14 P.S.I.A. Ethics factor .073

The personalia with correlations lower than .07 and higher than -.07 are left out here; this concerns year of birth, mother's and father's educational level, and the remaining P.S.I.A. scales.
