| Zerohedge Comment Article "Math Association Say Math "Inherently Carries Human Biases", Citing Critical Race Theory" Comment Title: The Persistent So-Called "Achievement Gap" Author: RobbieSmith Date: Oct 11th, 2020 The persistent so-called "achievement gap" reveals the same racial IQ hierarchy on standardized academic exams. The SAT is largely a measure of general intelligence. Scores on the SAT correlate very highly with scores on standardized tests of intelligence, and like IQ scores, are stable across time and not easily increased through training, coaching, or practice. SAT preparation courses appear to work, but the gains are small — on average, no more than about 20 points per section. Even after decades of focused attention to the achievement gap, it has remained unchanged. Vanderbilt University researchers tracked the educational and occupational accomplishments of more than 2,000 people who as part of a youth talent search and determined that scores on the SAT correlate so highly with IQ that they are described as a "thinly disguised" intelligence test.

The new SAT introduced in 2017 was "designed to inspire and increase access to college" by creating "a more equitable exam". The new SAT cannot be compared to previous results:
The 2017 "college readiness" scores (ability to earn a C or higher in an entry-level course) showed the stark racial achievement gap; Asians scored 70% college readiness, Whites 59%, and Blacks only 20%. (Source: U.S. Dept. of Education, College Board) https://nces.ed.gov/fastfacts/display.asp?id=171 SAT scores are highly correlated to intelligence test scores. The SAT correlates with an IQ test at 0.86, almost the same as an IQ test correlates with itself. For this reason, we can very reliably take SAT scores and convert them to IQ scores. Results of psycho-metric IQ and scholastic tests are highly correlated. Rindermann & Thompson (2013, p. 822) In the 20 year period from 1994-2014 the Black-White difference increased on both the verbal and math SATs despite targeted efforts to close the race gap. On the reading test, it rose from .91 to .96 standard deviations. On the math test, it rose from .95 to 1.03 standard deviations. In fact, the truncated nature of the SAT math score distribution suggests that these race gaps would be even larger given a harder exam with a bigger score variance. Note, for example, how the Black score distribution is cut off at the bottom while the Asian score distribution is cut off at the top. That suggests that a redesigned exam might feature even more pronounced race gaps. Percent by Race Reaching the SAT College and Career Readiness Benchmark:

"Unfortunately, the SAT is more of a test of what you have already learned. It does correlate to intelligence in that the IQ tests measure what you know, compared to what another person knows. In effect, does a 12 yr old know as much as a 16 yr old. The SAT is inherently biased toward students who have gone to a well funded, good teacher, school district, which has plenty of extra curricular courses. That's the way we like it. We want our children to have the better shot at college -- The ACT, however, is more of a test to see how much you are capable of learning, not what you already know. This is my personal preference, as it weeds out students incapable of learning college level courses." -- *QABubba* ========== ========== ========== ========== ========== ========== Author's reply to this comment...."It does correlate to intelligence in that the IQ tests measure what you know..." The racial IQ and brain size gap is present in infants and fetuses. The 1.1 SD (16 IQ points) American Black (24% White admixture)-White IQ gap is present by age three. The IQ gap between African Blacks and Whites is 2 SD. Race differences show up by 3 years of age, even after matching on maternal education and other variables. Therefore, they cannot be due to poor education since this has not yet begun to exert an effect. Even before birth, population group differences in average brain size are found from the ninth week of intrauterine life with White fetuses averaging larger brain cases and smaller faces than Black fetuses, with the differences becoming more prominent over the course of fetal development. Whole Brain Size and General Mental Ability: A Review https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2668913/ Racial differences in head size appear early in life. Head circumference of White children are greater than that of Black children in each age category by a mean of 0.36 cm³ or approximately 0.2 SD. The greater head size of White children, however, is not a function of greater body size because Black children are taller than White children at both 4 and 7 years (Broman et al., 1987). From 7 to 17 years, the White advantage in cranial capacity is 16 cm³. https://link.springer.com/content/pdf/10.3758%2FBF03210739.pdf Racial-group differences in IQ appear early. For example, the Black and the White 3 year-old children in the standardization sample of the Stanford–Binet IV show a 1 standard deviation mean difference after being matched on gender, birth order, and maternal education (Peoples, Fagan, & Drotar, 1995). Similarly, the Black and the White 2 1⁄2- to 6-year-old children in the U.S. standardization sample of the Differential Aptitude Scale have a 1 standard deviation mean difference (Lynn, 1996). The size of the average Black–White difference does not change significantly over the developmental period from 3 years of age and beyond (see Jensen, 1974, 1998b)." (Rushton & Jensen, 2005, pp. 240-241.) Farkas & Beron (2004) reported that blacks score 17.2 points below whites on the PPVT in this dataset at age 36 months (p. 478). More recently, Bond & Lang (2012) reported a slightly smaller, 14.6 point gap for 3-year-olds in this dataset (p. 13). Race differences in intelligence: An evolutionary
