Understanding (and) psychology - by sam - Apperceptive

Machine learning relies on psychological experiments at scale to label data but ignores the inherent difficulty in psychological measurement. The factors that need to be controlled to accurately measure concepts like intelligence are not intuitive. IQ tests in particular have been disproven as a valid measure of general intelligence, but the concept remains popular due to misconceptions about the ease of such measurements. A lack of understanding of psychological measurement leads to overconfidence in what models and tests can reliably capture. This same issue supports continued beliefs in racist ideologies that purport cognitive differences between groups but have long been debunked. Proper measurement requires expertise in controlling countless subtle factors, as shown by the careful development of the highly validated Cambridge Face Memory Test.
