Editing G factor (psychometrics) (section)

===Job attainment===

There is a high correlation of .90 to .95 between the prestige rankings of occupations, as rated by the general population, and the ''average'' general intelligence scores of people employed in each occupation. At the level of individual employees, the association between job prestige and ''g'' is lower – one large U.S. study reported a correlation of .65 (.72 [[Correction for attenuation|corrected for attenuation]]). Mean level of ''g'' thus increases with perceived job prestige. It has also been found that the [[Statistical dispersion|dispersion]] of general intelligence scores is smaller in more prestigious occupations than in lower level occupations, suggesting that higher level occupations have minimum ''g'' requirements.<ref name="s&h">Schmidt & Hunter 2004</ref><ref>Jensen 1998, 292–293</ref>
