David Marks (2010) argues that differences in average IQ scores between national groups and across time periods can be fully accounted for by differences in literacy levels, and that "IQ distributions will converge if opportunities are equalized for different population groups to achieve the same high level of literacy skills."

Florida's metropolitan areas and major cities Florida's population density per square mile Florida ancestry map. With a population getting close to 23 million people according to the 2023 US Census estimates, [7] [12] Florida is the most populous state in the Southeastern United States, and the second-most populous state in the South behind ...
More recent research attempting to identify genetic loci associated with individual-level differences in IQ has yielded promising results, which led the editorial board of Nature to issue a statement differentiating this research from the "racist" pseudoscience which it acknowledged has dogged intelligence research since its inception.

[31] [32] Not all report test results as "IQ", but most now report a standard score with a mean score level of 100. When a test-taker scores higher or lower than the median score, the score is indicated as 15 standard score points higher or lower for each standard deviation difference higher or lower in the test-taker's performance on the test ...
Re-analysis, and subsequent studies, have established that general mental ability (IQ) predicts job performance across all jobs. [9] The validity of IQ varies most notably with job complexity: IQ matters little for simple jobs such as packing, and a great deal in complex jobs such as medicine. These findings have major significance.
The debate concerns possible explanations of group differences encountered in the study of race and intelligence. Since the beginning of IQ testing around the time of World War I there have been observed differences between average scores of different population groups, though these differences have fluctuated and in many cases steadily ...

An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
