I just stumbled across a relatively new video covering the history and several major issues regarding intelligence testing and IQ scores. Two scholars that I respect (Dr. Cecil Reynolds; Dr. Stuart Ritchie) are featured in the video. I did see some spelling errors in the subtitles (Dr. Ian Dearie instead of Dr. Ian Deary; Benet instead of Binet; using capital G when referencing Spearman's concept of general intelligence, which is always noted with an italic font small g; etc) and heard several statements that made me cringe slightly.
Also, it left the impression that fluid and crystallized intelligence (and a lessor extent quantitative ability) are the primary recognized broad cognitive abilities measured by intelligence tests. It did not acknowledge contemporary CHC theory as the consensus taxonomy of human cognitive abilities. Also, it left the impression that IQ tests are "bubble in" multiple choice tests. This may be true for group tests, but it is not the case with individually administered intelligence tests.
Overall, it is a reasonable video to share with others as an introduction, possibly in college courses where the concept of intelligence and IQ testing is being introduced. It did a good job of covering the historical bad uses of IQ tests (e.g., discrimination; cultural bias, eugenics movement, etc.)
The complete video is approximately 35 minutes. It did freeze up for me at the 17 minute mark when it was going to display an ad....but I simply restarted the video and quickly moved to that point and then it continued.
