"....Gould's (1981, The Mismeasure of Man) strawman issue of the reification of g was dealt with satisfactorily by the pioneers of factor analysis, including Spearman (1927), Burt (1940) and Thurstone (1947).....From Spearman to Meehl (1991, History of Philosophy & Psychology Bulletin), the consensus of experts is that g need not be a "thing"....The g factor is a construct. Its status as such is comparable to other constructs in science: mass, force, gravitation, potential energy, magnetic field, Mendelian genes, and evolution, to name a few."
