Scientific Racism to The End of Rwanda Flashcards
Why do some scientists argue that races exist?
either biological determinism, reductionists (both biases)
biological determinism
the belief that biological characteristics of an individual determine behaviours
reductionists
they oversimplify complex patterns and reduce them to single determinants
biases
a systematic distortion of results due to factors not considered important
Are human behaviours genetically determined?
two schools of thought believe the answer is yes: sociobiology and evolutionary psychology
sociobiology and evolutionary psychology both study the…?
evolutionary explanations for s.behaviours and assume that they are “genetically inherited”
Basis of Sociobiology
goal is to understand human behaviours that are aimed at passing ones genes into the next generation
- natural selection favoured certain behaviours in certain environments because they helped an individual service and reproduce
Basis of Evolutionary Psychology
attempted to understand the evolution of the human mind
- our brains were designed by natural selection to solve problems that our ancestors faced during our species’ evolutionary history
Criticisms of sociobiology and evolutionary psychology
- to date, there is no evidence that behaviours in humans are genetic in origin
- both assume that behaviours are adaptive and are the result of natural selection
- cultural evolution proceeds much faster than biological evolution and both assume that - cultural universals are biological in origins.
they argue that all these processes are subconscious
Sociobiology and Evolutionary Psychology DO NOT
try to explain differences between human groups because of genetics (applies to all humans), promote racists ideologies or social and/or political agendas.
Human Sociobiology
studies based on the premise that human races are fundamentally different in their biology and in their behaviours and these are shaped by natural selection.
J.P Rushton
argued that certain people are more k-selected (emphasis on child rearing). This, he argued, was due to evolutionary history, in other words, natural selection has made made human races different in personality, sexual behaviour, and many other traits.
R-selected species
had many undesirable traits such a low intelligence, little altruism, and low degrees of social organization
K-selected species
had characteristics such as high intelligence, lots of altruism, etc.
Rushton identified three races
blacks, whites, and asian
Rushton’s Evidence…
- Higher infant mortality in Africa suggests low degree of parental care, plus an overall lower lifespan
- In Africa, people reproduce at an early age and large numbers of children are produced, as well as African women have children with many fathers to maximize reproductive potential (promiscuity)
- There are no advanced civilization in Africa, indication low altruism
- In Asia, there is the lowest infant mortality rate and birthrate, delayed reproduction and monogamous relationships occur, they as well have highly advanced civilization, intelligent and long lifespans.
Rushton’s Conclusions
Blacks are the most r-selected, Asians are the most k-selected, Whites are intermediated
Methodological Errors in Rushton’s Study
1) Arbitrary classification of populations into three races with no justifications
2) Misuse of r-selected and k-selected concepts
- neglects environmental variables, ignores his own model, the purpose is compare species, not subgroups
3) Selective use of data to represent the three “races”
- he does not use averages when calculating birthrate, just the statistics that support his conclusion
4) Misleading use of variable that are not relevant to study
- Genital Size: it was thought that men’s reproductive success depended on the amount of sperm, Rushton used a 100 year old study to argue that black people had the largest penis
- Intelligence: Rushton used studies on craniometry to persuade his readers that his assessment was correct
5) Rushton dismissed social, economic, and religious factors in explaining differences between the human populations. (China’s One-Child policy)
Intelligence, I.Q., and Races: What is the debate?
Are some “races” more intelligent than others? Is intelligence genetically inherited? Are I.Q. tests a valid measure of intelligence?
Methodological Problems with
Intelligence, I.Q., and Races
intelligence is difficult to define and researchers do not agree on a definition of the term, differences can be due to genetic factors (heritability), social factors and I.Q. tests are culturally biased.
Arguments Against Genetic Heritability
most children have an I.Q. different (usually higher) from the parents, adoptive children’s I.Q. scores are more similar to their adaptive parents than their biological.
