The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century, named after researcher James Flynn (1934–2020).
A study shows a sharp decline in three key intelligence testing categories—a tangible example of what is called the Reverse Flynn Effect. American IQ Scores Have Rapidly Dropped, Proving the ...
A paper from Drew Thomas (2016) found that once corrected for the Flynn effect and attrition in the low IQ white adoptees, the MTRA data showed mixed adoptees scoring slightly lower than white adoptees with a gap of 2.5 points at age 7 and 3.5 at age 17, while black adoptees scored 12.2 and 11.7 points below white adoptees at ages 7 and 17 ...
Flynn did not believe genetic differences in intelligence between races existed; he argued that intelligence is influenced by environmental factors that correlate with socioeconomic status. [10] [4] [9] The "Flynn effect" is the substantial and long-sustained increase in intelligence test scores measured in many parts of the world.
Popular examples of the Mandela effect. Here are some Mandela effect examples that have confused me over the years — and many others too. Grab your friends and see which false memories you may ...
The identical twins paradox – past IQ research has shown a close relation between the IQs of identical twins reared separately; a fact used as evidence for a genetic basis for differences in IQ. The rapid changes in IQ shown by the Flynn effect suggest, conversely, that environmental factors have a greater influence on IQ than genes.
Third, arguments based on Spearman's hypothesis have been criticized. Some have argued that culturally caused differences could produce a correlation between g-loadings and group differences. Flynn (2010) has criticized the basic assumption that confirmation of Spearman's hypothesis would support a partially genetic explanation for IQ differences.
