Correlation between intelligence test scores and success in certain rational organization problems

Scores on the Otis Self-Administering Tests and the Detroit Advanced Intelligence Test were correlated with scores on a rational learning test, two forms of a rational analysis problem, and an analogy test. The rational learning test required the subject to learn to associate certain letters and numbers together, while the rational analysis problem required the subject to discover which member from each of eight pairs of letters the experimenter had selected. Small but reliably positive correlations were found between the rational learning scores and intelligence test scores, and somewhat larger correlations between analogy scores and intelligence test scores. The rational analysis tests showed no relation to intelligence tests, and it is suggested that they may serve better to study types of thinking than to analyze specific abilities.
