Thanks for sharing the quotation from Alfred Binet, developer of the first practical IQ test battery (for the unambitious purpose of efficient school placement of elementary pupils in schools with lock-step age grading). His view was correct then, and it is still correct today, but widely ignored.
More recent authors who criticize the mainstream psychometric concept of intelligence (operationalized as IQ scores) include Keith Stanovich.
