Subclaims¶

q2 i? Assuming construction tests better measure general ability, Thorndike found Binet age correlated more highly with language tests than with a construction test and concluded the Binet scale is inadequate. → Kohs 1917

Evidence¶

Entry 394 annotates Thorndike's 1916 Psychological Clinic article: "the correlations between Binet age and "language" tests are higher than those between Binet age and a construction test," leading to the stated inadequacy conclusion. No coefficients are printed in the annotation.

"it is found that the correlations between Binet age and "language" tests are higher than those between Binet age and a construction test. Therefore the Binet scale is inadequate."
