Subclaims¶

q2 i? A test score prophesies book-learning responses rather accurately, less accurately responses to concrete realities such as machines, crops and merchandise, and still less accurately thinking about people and their passions. → E. L. Thorndike and L. M. Terman 1921

Thorndike's illustrative argument about a 12-year-old boy's score on a combination of named tests: it will prophesy book-learning rather accurately, but "less accurately" for concrete realities and still less for responding to people. This is the author's stated claim, not a reported study.

"It will prophesy less accurately how well he will respond in thinking about a machine that he tends, crops that he grows, merchandise that he buys and sells and other concrete realities that he encounters in the laboratory, field, shop and office."

Related Claims¶

• Important intellectual differences among people are not found on the sensory, perceptual, or purely reproductive level — related
• Correlations between performance on different intellectual tasks fail to reach 1.00, indicating specialization of intelligence — a broader claim this one bears on
