Ranking in above table is based on the unrounded correlations. All available data is present in this table, no tests are left out except for those with less than 4 score pairs. All known pairs are used, including possible floor/ceiling scores or outliers.
Please be aware that correlations with these external tests are in most cases affected (depressed, typically) by one or more of the following: (1) Little overlap with the object test because of the much lower ceilings and inherent ceiling effects of the tests used in regular psychology; (2) Candidates reporting scores selectively, for instance only the higher ones while withholding lower ones; (3) Candidates reporting, or having been reported by psychometricians, incorrect scores.
These are estimated g factor loadings, but against homogeneous tests (containing only particular item types) as opposed to non-compound heterogeneous tests. Although tending to surprise the lay person, it is not uncommon for tests to have high loadings on item types they do not actually contain themselves. Such loadings reflect the empirical fact that most tests for mental abilities measure primarily g, regardless of their contents; that the major part of test score variance is caused by g, and only a minor part by factors germane to particular item types. It is of key importance to understand that this is a fact of nature, a natural phenomenon, and not something that was built into the tests by the test constructors.

In parentheses the number of score pairs on which that estimated g factor loading is based. The goal of this is to verify the hypothesis that g becomes less important, accounts for a smaller proportion of the variance, at higher I.Q. levels. The mere fact of restricting the range like this also depresses the g loading compared to computing it over the test's full range, so it would be normal for both values to be lower than the test's full-range g loading.
Raw score | Upward g (n) | Downward g (n) |
---|---|---|
0 | 0.73 (664) | NaN (0) |
23 | 0.64 (570) | 0.86 (32) |
25.5 | 0.49 (482) | 0.70 (103) |
28 | 0.49 (471) | 0.69 (125) |
30.5 | 0.58 (386) | 0.75 (226) |
33 | 0.29 (235) | 0.70 (404) |
35.5 | 0.60 (82) | 0.69 (485) |
38 | 0.93 (5) | 0.72 (648) |
42 | NaN (0) | 0.73 (664) |
Remark: Reliability is a bit low, and this is caused by the easy nature of the test, as a result of which most of the scores are concentrated in a fairly small part of the test's possible range. This is also a cause of the somewhat low g loading. The easiness of the test also lowers overall test quality.

Item statistics are not published as that would help future candidates. To detect bad items, answers and comments from candidates are studied, as well as, for each problem, the correlation with total score and the proportion of candidates getting it wrong (hardness of the item). Possible bad items are removed or revised, resulting in a revised version of the test.
