Editing G factor (psychometrics) (section)

===Creativity===

Some researchers believe that there is a threshold level of ''g'' below which socially significant [[creativity]] is rare, but that otherwise there is no relationship between the two. It has been suggested that this threshold is at least one standard deviation above the population mean. Above the threshold, personality differences are believed to be important determinants of individual variation in creativity.<ref>Jensen 1998, 577</ref><ref>Eysenck 1995</ref>

Others have challenged the threshold theory. While not disputing that opportunity and personal attributes other than intelligence, such as energy and commitment, are important for creativity, they argue that ''g'' is positively associated with creativity even at the high end of the ability distribution. The longitudinal [[Study of Mathematically Precocious Youth]] has provided evidence for this contention. It has shown that individuals identified by standardized tests as intellectually gifted in early adolescence accomplish creative achievements (for example, securing patents or publishing literary or scientific works) at several times the rate of the general population, and that even within the top 1 percent of cognitive ability, those with higher ability are more likely to make outstanding achievements. The study has also suggested that the level of ''g'' acts as a predictor of the ''level'' of achievement, while specific cognitive ability patterns predict the ''realm'' of achievement.<ref>Lubinski 2009</ref><ref>Robertson et al. 2010</ref>
