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 for 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 linguistic "bias" (which in actuality is quite small to non-existent). 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 not harder on the whole than homogeneous ones.

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

rn/yr × q = -0.11 (over 116 tests with at least 1 score each)

rn/yr × q = -0.12 (over 78 tests with at least 16 scores each)

rn/yr × q = -0.14 (over 58 tests with at least 25 scores each)

rn/yr × q = -0.15 (over 42 tests with at least 36 scores each)

rn/yr × q = -0.21 (over 31 tests with at least 49 scores each)

rn/yr × q = -0.22 (over 28 tests with at least 64 scores each)

rn/yr × q = -0.22 (over 28 tests with at least 81 scores each)

rn/yr × q = -0.30 (over 14 tests with at least 100 scores each)

rn/yr × q = -0.26 (over 10 tests with at least 121 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 harder on the whole 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, although numerical and spatial tests are easier than logical and verbal tests.
