Hereditarian
Hereditarianism is the doctrine or school of thought that heredity plays a significant role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetics to explain human character traits and solve human social and political problems. Hereditarians adopt the view that an understanding of human evolution can extend the understanding of human nature. Overview Social scientist Barry Mehler defines hereditarianism as "the belief that a substantial part of both group and individual differences in human behavioral traits are caused by genetic differences". Hereditarianism is sometimes used as a synonym for biological or genetic determinism, though some scholars distinguish the two terms. When distinguished, biological determinism is used to mean that heredity is the only factor. Supporters of hereditarianism reject this sense of biological determinism for most cases. However, in some cases genetic determinism is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Race And Intelligence
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. With the inception of IQ testing in the early 20th century, differences in average test performance between racial groups were observed, though these differences have fluctuated and in many cases steadily decreased over time. Further complicating the issue, modern science has shown race to be a social construct rather than a biological reality, and intelligence has no undisputed definition. The validity of IQ testing as a metric for human intelligence is itself disputed. Today, the scientific consensus is that genetics does not explain differences in IQ test performance between groups, and that observed differences are environmental in origin. Pseudoscientific claims of inherent differences in intelligence between races have played a central role in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heritability Of Intelligence
Research on the heritability of IQ inquires into the degree of variation in IQ within a population that is due to genetic variation between individuals in that population. There has been significant controversy in the academic community about the heritability of IQ since research on the issue began in the late nineteenth century. Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, and in the case of intelligence at least 500 genes. Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors. Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults. The heritability of IQ increases with the child ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the con ...

Hereditary Genius
''Hereditary Genius: An Inquiry Into Its Laws and Consequences'' is a book by Francis Galton about the genetic inheritance of intelligence. It was first published in 1869 by Macmillan Publishers. The first American edition was published by D. Appleton & Company in 1870. It was Galton's first major work written from a hereditarian perspective. It was later referred to as "the first serious study of the inheritance of intelligence" and as "the beginning of scientific interest in the topic of genius." In the book, Galton demonstrated that the sons of men who he considered "eminent" in a given profession were more likely to achieve such eminence themselves than if they were not closely related to eminent individuals. He interpreted this pattern as evidence for genetic transmission of human intelligence. Contemporary reception Alfred Russel Wallace wrote a favourable review of ''Hereditary Genius'' in ''Nature'', concluding that the book "...will take rank as an important and valuab ...

Charles Murray (political Scientist)
Charles Alan Murray (; born 1943) is an American political scientist. He is the W.H. Brady Scholar at the American Enterprise Institute, a conservative think tank in Washington, DC. Murray's work is highly controversial. His book '' Losing Ground: American Social Policy, 1950–1980'' (1984) discussed the American welfare system. He co-wrote the book ''The Bell Curve'' (1994), co-authored with Richard Herrnstein, in which the authors argue that in American society, in the course of the 20th century, intelligence became a better predictor than parental socioeconomic status or education level of many individual outcomes, including income, job performance, pregnancy out of wedlock, and crime, and that social welfare programs and education efforts to improve social outcomes for the disadvantaged are largely counterproductive. ''The Bell Curve'' also claimed that average intelligence quotient (IQ) differences between racial and ethnic groups are at least partly genetic in origin, a vi ...

Heredity
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics. Overview In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment. As a result, many aspects of an organism's phenotype are not inherited. For example, suntanned sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Behaviorism
Behaviorism is a systematic approach to understanding the behavior of humans and animals. It assumes that behavior is either a reflex evoked by the pairing of certain antecedent stimuli in the environment, or a consequence of that individual's history, including especially reinforcement and punishment contingencies, together with the individual's current motivational state and controlling stimuli. Although behaviorists generally accept the important role of heredity in determining behavior, they focus primarily on environmental events. Behaviorism emerged in the early 1900s as a reaction to depth psychology and other traditional forms of psychology, which often had difficulty making predictions that could be tested experimentally, but derived from earlier research in the late nineteenth century, such as when Edward Thorndike pioneered the law of effect, a procedure that involved the use of consequences to strengthen or weaken behavior. With a 1924 publication, John B. Wats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steven Pinker
Steven Arthur Pinker (born September 18, 1954) is a Canadian-American cognitive psychologist, psycholinguist, popular science author, and public intellectual. He is an advocate of evolutionary psychology and the computational theory of mind. Pinker is the Johnstone Family Professor of Psychology at Harvard University, and his academic specializations are visual cognition and developmental linguistics. His experimental subjects include mental imagery, shape recognition, visual attention, children's language development, regular and irregular phenomena in language, the neural bases of words and grammar, as well as the psychology of cooperation and communication, including euphemism, innuendo, emotional expression, and common knowledge. He has written two technical books that proposed a general theory of language acquisition and applied it to children's learning of verbs. In particular, his work with Alan Prince published in 1989 critiqued the connectionist model of how children ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Blank Slate
''The Blank Slate: The Modern Denial of Human Nature'' is a best-selling 2002 book by the cognitive psychologist Steven Pinker, in which the author makes a case against tabula rasa models in the social sciences, arguing that human behavior is substantially shaped by evolutionary psychological adaptations. The book was nominated for the 2003 Aventis Prizes and was a finalist for the Pulitzer Prize. Summary Pinker argues that modern science has challenged three "linked dogmas" that constitute the dominant view of human nature in intellectual life: * the blank slate (the mind has no innate traits)—empiricism * the noble savage (people are born good and corrupted by society)—romanticism * the ghost in the machine (each of us has a soul that makes choices free from biology) Much of the book is dedicated to examining fears of the social and political consequences of his view of human nature: * "the fear of inequality" * "the fear of imperfectibility" * "the fear of determinism ...

Environmental Determinism
Environmental determinism (also known as climatic determinism or geographical determinism) is the study of how the physical environment predisposes societies and states towards particular development trajectories. Jared Diamond, Jeffrey Herbst, Ian Morris, and other social scientists sparked a revival of the theory during the late twentieth and early twenty-first centuries. This "neo-environmental determinism" school of thought examines how geographic and ecological forces influence state-building, economic development, and institutions. Many scholars underscore that this original approach was used to encourage colonialism and eurocentrism, and devalued human agency in non-Western societies, whereas modern figures like Diamond have instead used the approach as an explanation that rejects racism.Gilmartin, M.

Social Determinism
Social determinism is the theory that social interactions alone determine individual behavior (as opposed to biological or objective factors). A social determinist would only consider social dynamics like customs, cultural expectations, education, and interpersonal interactions as the contributing factors to shape human behavior. Non-social influences, like biology, would be ignored in their contribution towards behavior. Thus, in line with the nature-nurture debate, social determinism is analogous to the 'nurture' side of the argument. Overview Social determinism was studied by the French philosopher Emile Durkheim (1858 - 1917), who was considered the father of social science. Social determinism is most commonly understood in opposition to biological determinism. However, within the media studies discipline, social determinism is understood as the counterpart of technological determinism. Technological determinism is the notion that technological change and development are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Versus Nurture
Nature versus nurture is a long-standing debate in biology and society about the balance between two competing factors which determine fate: genetics (nature) and environment (nurture). The alliterative expression "nature and nurture" in English has been in use since at least the Elizabethan period and goes back to medieval French. The complementary combination of the two concepts is an ancient concept ( grc, ἁπό φύσεως καὶ εὐτροφίας). Nature is what people think of as pre-wiring and is influenced by genetic inheritance and other biological factors. Nurture is generally taken as the influence of external factors after conception e.g. the product of exposure, experience and learning on an individual. The phrase in its modern sense was popularized by the Victorian polymath Francis Galton, the modern founder of eugenics and behavioral genetics when he was discussing the influence of heredity and environment on social advancement. Galton was influenced by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
