q1 · i? · review · r?

The reviewer's own critical assessment of the Goddard volume, noting that "Technical matters, such as the validity of the Intelligence Quotient, are omitted" and questioning whether the constant-growth impression is literally meant. The review concludes the book is a clear, interesting account of intelligence testing.

"Technical matters, such as the validity of the Intelligence Quotient, are omitted. Certain charts and statements give the impression that the writer considers all individuals to have a constant growth"

• Goddard's book argues that intelligence level is the determining factor in human efficiency, with other traits treated as subsidiary — related

• IQs obtained by dividing mental by chronological age remain fairly constant up to the age of 14, which supports treating yearly increments of intelligence as equal absolute units up to about age 14. — related
• The reviewed intelligence-testing book omits technical questions such as the validity of the Intelligence Quotient and presents testing results optimistically — possibly the same claim (merge candidate)
