1. Let x1, x2, x3 represent three mental activities; r12 the correlation coefficient of x1 and x2; r23 that of x2 and x3; r31 that of x3 and x1.J. Ridley Thompson has shown (Brit. Journ. Psychol., 1919, vol. ix, p. 335) that ifF(r)≡r122 + r232 + r312 + 2r12r23r31be greater than 1, a “general factor” is undoubtedly present in the three activities.
