Galton and sex differences: an historical note.

The psychological study of sex differences is a special area of interest within differential psychology. Differential psychology was launched as a scientific field of research in the latter half of the nineteenth century by Sir Francis Galton. Galton's early research on sex differences in psychological traits gives him the distinction of being the "father" of the modern study of sex differences. Galton's empirical findings and his interpretation of sex differences were heavily influenced by his Victorian sexist attitudes. The early history of the modern study of sex differences exemplifies the intimate relation between facts and values.
