<P> Charles Spearman developed his two - factor theory of intelligence using factor analysis . His research not only led him to develop the concept of the g factor of general intelligence , but also the s factor of specific intellectual abilities . L.L. Thurstone , Howard Gardner , and Robert Sternberg also researched the structure of intelligence , and in analyzing their data , concluded that a single underlying factor was influencing the general intelligence of individuals . However , Spearman was criticized in 1916 by Godfrey Thomson , who claimed that the evidence was not as crucial as it seemed . Modern research is still expanding this theory by investigating Spearman 's law of diminishing returns , and adding connected concepts to the research . </P>
