Differences in intelligence have long been a topic of debate among researchers and scholars. With the advent of the concept of g or general intelligence, many researchers demonstrated no significant sex differences in g factor or general intelligence while others have argued for greater intelligence for males. The split view between these researchers depended on the methodology and tests they used for their claims. One study did find some advantage for women in later life, while another found that male advantages on some cognitive tests are minimized when controlling for socioeconomic factors.
