Explain Three Reasons Why Racial Differences in Intelligence
The intellectual differences between races are mainly caused by genetic differences in particular differences in the frequency of alleles linked to high and low intelligence involved in brain size nerve conduction or in different neurophysiological processes. Whites brains average 6-8 larger.

Reasons we know that the intelligence gap between Whites and Blacks is genetically based.
. Historical evidence also seems to support the hypothesis that the black-white test score gap falls when class size. In causing differences in physical traits this factor is prominent. In a few cases medical treatment and medication showed racial differences.
Some researchers argue that stereotype threat or the fear of confirming negative stereotypes may cause racial and ethnic minority students to score. The experiment also found that gains were much larger for blacks than for whites. Which proves a real quagmire for race equality dogmatist.
The general results of all studies made point to the fact that the differences between sexes are quite insignificant. A third explanation for US racial and ethnic inequality is based in conflict theory and reflects the blaming-the-system approach outlined in Chapter 1 Understanding Social ProblemsThis view attributes racial and ethnic inequality to structural problems including institutional and individual discrimination a lack of opportunity in education and other spheres. All of the following help explain racial differences in IQ scores EXCEPT.
They held up the apparent gaps these tests. Differences in intelligence have been shown to be highly stable from early adolescence to late adulthood Deary Pattie Starr 2013 but are more variable in infancy and childhood with some children showing substantial gains in intelligence and others considerable losses between infancy and adolescence Bayley 1955 Feinstein 2003 Tucker-Drob and Briley 2014. --Test scores have increased over time the Flynn effect by an amount greater than the race diff erence--When Blacks and Whites have or receive the same pertinent knowledge they exhibit similar information- processing skills--Schools and culture matter--In different historical eras different ethnic groups have flourished.
Individuals differ in their attitudes towards different people objects institutions and authority. With the inception of IQ testing in the early 20th century differences in average test performance between racial groups were observed though these. Due to limited or non-existent health care particular racial and ethnic groups are at greater risk for sensory loss and other health problems that may lower their performance on intelligence measures for example higher blood lead levels leading to cognitive deficits.
By adulthood East Asians average 1 cubic inch more cranial capacity than Whites who average 5 cubic inches more than Blacks. As soon as the subject turned to the question of IQ they focused on whether there was any genetic race differences in intelligence. Explain three reasons why racial differences in intelligence might.
There are pervasive physical differences between Whites and Blacks including brain size and structure bone density muscularity fat storage hormones and metabolic rate. Another argument that is often made to salvage the genetic determination by racial group of intelligence is the between nation data that has been more recently assembled and foisted on us. One important thing to note about the genetics of intelligence is that it is not controlled by a single intelligence gene Instead it is the result of complex interactions between many genes.
INTELLIGENCE DIFFERENCES are genetic. This research suggests that genetics may play a larger role than environmental factors in determining individual IQ. Although not discounting them the possibility was considered that they were on a smaller scale than previously supposed and also due to factors other than heredity.
1 we think there is currently no good reason to believe. These differences are very much visible in reading writing and in learning mathematics. Race differences in brain size are present at birth.
This study suggests that the superiority of city children over rural children is a direct consequence of better cultural opportunities. Race differences in IQ remain following. Find step-by-step solutions and your answer to the following textbook question.
In the 1920s psychologists started questioning underlying assumptions of racial differences in intelligence. It has been found through achievement tests that individuals differ in their achievement abilities. Ethnocentrics and eugenicists who viewed intelligence and other social behaviours as being determined by biology and race latched onto IQ tests.
So here then is where we differ with Murray and as we understand it with Harris. Discussions of race and intelligence specifically claims of differences in intelligence along racial lines have appeared in both popular science and academic research since the modern concept of race was first introduced. In amazing ways Rushton forms a coherent picture to make sense of all the racial differences shown in reasearch.
Some differences are biological and can not be talked away by simple psychobabble or sociology-babble.
