After nearly a century of IQ testing and [[educational reform]]s, some researchers have begun to assert that IQ can be influenced by the child's environment by as much as 30 points.<ref>3 weeks of intensive play of WFF 'N PROOF: The Game of Modern Logic increased average IQ scores by more than 20 points.

A 1976-year study that covered 258 children (IQ between 80 and 119) finally concluded that the major correlating factor is "a favorable parental social and educational background".<ref>Fisch RO, Bilek MK, Horrobin JM, Chang PN (1976) Children with superior intelligence at 7 years of age: a prospective study of the influence of perinatal, medical, and socioeconomic factors.

[[Socioeconomics|Socioeconomic]] factors can cause differences in regional intelligence levels (for example, wealth which can affect the quality of education, health care and nutrition). Although social scientists have disputes about the accuracy of IQ scores in a given region, regions do vary in terms of their IQ scores.<ref name="CountryIQ">[https://iq-research.info/en/page/average-iq-by-country WORLD RANKING OF COUNTRIES BY THEIR AVERAGE]</ref><ref name="NatureIQ">[http://www.nature.com/hdy/journal/v92/n4/full/6800418a.html Book Review: IQ and the Wealth of Nations], ''Nature''</ref><ref name="AfricanIQ">[https://www.sciencedaily.com/releases/2010/01/100121155220.htm Controversial study of African IQ levels is 'deeply flawed'], Science Daily, January 21, 2010</ref> Ethnic groups facing discrimination as immigrants and their IQs temporarily dropping and then later rebounding when the discrimination is over, strongly suggests that IQ is significantly affected by one's environment and not due to any inherent and permanent genetic differences between races.<ref>[https://www.motherjones.com/kevin-drum/2017/05/charles-murray-still-convinced-whites-are-smarter-blacks Charles Murray Still Convinced That Whites Are Smarter Than Blacks] by Kevin Drum, ''Mother Jonees'', 2017</ref>
