Personality Scales for Intelligent Adults - Statistics of Cold scale

© Paul Cooijmans


These statistics are from the version of the PSIA that was in use from 2003 to 2007, and was highly similar to the later Revision 2007. The scores are t-scores (mean = 50, σ = 10) normed on an earlier group (partly overlapping this one) so this group may not have an exact mean and σ of 50 and 10. An explanation of the scale can be found through the test's order page.

Explanatory and analytical remarks regarding the interpretation of the statistics are purposely largely avoided, so it is up to the reader to study the report carefully and thus obtain a clear impression of the test's validity — that is, "what it measures". Although the statistics sometimes reveal an almost chilling discriminative power, experience shows that explicitly observing that in a remark tends to evoke negative responses in persons who recognize themselves ("Your remark betrays that your are biased! The test only measures your personal biases!", et cetera).

Estimated loadings of PSIA Cold on particular item types

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.

Typeng loading of PSIA Cold on that type

N = 662

Compound tests have been left out of this table to avoid overlap.

Balanced g loading = 0.12

Estimated g factor loadings for restricted ranges

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 these values to be lower than the test's full-range g loading.

Below 1st quartile0.59 (111)
Below median0.25 (405)
Above median0.29 (554)
Above 3rd quartile0.27 (189)

Positive g factor loading on the whole, as well as a large sex difference. This scale is interesting in that it apparently contains the aspect of the Aspergoid nature that is not disordered and does not cripple intelligence; in other words, the aspect that contributes to creativity by making for a wide associative horizon. It does so in conjunction with introversion. Associative horizon seems to be a combination of Cold and Introverted, or otherwise said the Aspergoid nature minus the crippling disorders.
