The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities. First described in humans, the g factor has since been identified in a number of nonhuman species. [46]
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
[127] [128] These values are similar to the accepted variance in IQ explained by a similar single factor known as the general factor of intelligence in humans (40-50%). [129] However, results from a recent meta-analysis suggest that the average correlation between performance scores on various cognitive tasks is only 0.18. [ 130 ]
Dunbar's number has become of interest in anthropology, evolutionary psychology, [12] statistics, and business management.For example, developers of social software are interested in it, as they need to know the size of social networks their software needs to take into account; and in the modern military, operational psychologists seek such data to support or refute policies related to ...
