Number of scores occurring per year (n/yr) by number of item types contained

It could not be more clear: Homogeneous (one-sided) tests are by far the most popular. Candidates, when allowed to follow their own preferences and not guided into more sensible ways, choose to have it easy and take mainly or only tests that fit their strongest side. Test constructors who are only in for the money and fame cater their candidates' regrettable whims, resulting in score inflation and the tsunami of unbalanced characters claiming the world's highest "I.Q." we all loathe so much.

Verbal tests are always by very far the most accessible and attractive to a broad audience, despite popular notions of cultural or linguistical "bias" (which in actuality is quite small to nonexistent). Of the non-verbal tests, visual-spatial ones are the most popular. Numerical and logical tests are feared to some extent; this is probably the wide-spread fear of mathematics and (formal, symbolic) logic among the general "alpha" public.

Contrary to people's dislike for them, heterogeneous tests are on the whole not harder than homogeneous ones.

Correlation number of scores occurring per year on test × test hardness

rn/yr × q = -0.10 (over 100 tests with at least 1 score each)

rn/yr × q = -0.15 (over 33 tests with at least 30 scores each)

rn/yr × q = -0.32 (over 19 tests with at least 60 scores each)

rn/yr × q = -0.32 (over 7 tests with at least 120 scores each)

Although this appears a slight negative correlation, one expects a somewhat larger negative correlation with the true, population-independent, test hardness. This correlation means that easier tests are more popular than harder tests. The fact that hardness as meant here is computed in relation to the group of candidates having taken the test may attenuate the correlation toward zero, on the understanding that a (truly) harder test will attract a smaller sample with a higher average level, and that therefore the average score of the sample shifts upward with true hardness, thus hiding the correlation.

Conclusions summarized

  1. Homogeneous (one-sided) tests are far more popular than heterogeneous (multi-sided, mixed-item) tests;
  2. Easier tests are more popular than harder tests;
  3. Heterogeneous tests are not on the whole harder than homogeneous tests, despite candidates' apparent dislike or fear of them;
  4. Of the homogeneous tests, verbal tests are the most popular, even though in a foreign language for many of the candidates;
  5. Of the homogeneous non-verbal tests, visual-spatial tests are the most popular;
  6. The various types of homogeneous tests do not differ much in hardness.
