Spearmen's theory of intelligence consisted of two factors: general (g) and specific (s). The g factor tended to include one's ability to 1) acquire and retain information from experience, 2) infer relationships between two things, and 3) infer principles to new domains.
Spearman's g factor, proposed by psychologist Charles Spearman, is a statistical measure of the strength of the relationship between two sets of ranks. It represents the general intelligence factor underlying specific mental abilities and is believed to be one of the key elements of human intelligence. The g factor is used in psychometric theories to explain individual differences in cognitive abilities.

The g factor, or general intelligence factor, is a psychological construct that represents a person's overall cognitive ability to perform various mental tasks. It is thought to underlie performance on a wide range of cognitive tasks and is often measured through standardized intelligence tests.
