Hereditarianism is the research program according to which heredity plays a central role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetic influences to explain human behavior and solve human social-political problems.
Guided democracy, also called directed democracy [110] and managed democracy, [111] [112] is a formally democratic government that functions as a de facto authoritarian government or, in some cases, as an autocratic government. [113] Such hybrid regimes are legitimized by elections, but do not change the state's policies, motives, and goals ...
The most cited adoption projects that sought to estimate the heritability of IQ were those of Texas, [8] Colorado [9] and Minnesota [10] that were started in the 1970s. These studies showed that while adoptive parents IQ does seem to have a correlation with adoptees IQ in early life, when the adoptees reach adolescence the correlation has faded ...
The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by the psychologist Richard J. Herrnstein and the political scientist Charles Murray in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance ...
Studies of human heritability often utilize adoption study designs, often with identical twins who have been separated early in life and raised in different environments. Such individuals have identical genotypes and can be used to separate the effects of genotype and environment.

[1] It generally stems from beliefs within the dominant group that their cultural practices are superior to those of minority groups [2] and is often related to the concept of ethnocentrism, which involves judging another culture based on the values ...
The power of twin designs arises from the fact that twins may be either identical (monozygotic (MZ), i.e. developing from a single fertilized egg and therefore sharing all of their polymorphic alleles) or fraternal (dizygotic (DZ), i.e. developing from two fertilized eggs and therefore sharing on average 50% of their alleles, the same level of genetic similarity found in non-twin siblings).
