Of the 35 misconceptions in this book, one of the most common is the belief that intelligence tests are biased against African Americans, Hispanics, and Native Americans. In one study of introductory psychology textbooks, this was the most common inaccuracy that authors perpetuated (Warne et al., 2018). Indeed, this belief often extends to academic tests and tests used for hiring and promotion (Reeve & Charles, 2008). Because these tests also measure g (see Chapter 7), it is unsurprising that people often believe that these tests, too, are biased against diverse groups.
