The appendix in Spc.trman's book provides the www.fbi-gogogo.com/ tetrad equations, the mathematics underlying factor analysis, while die much longer text reebok easytone is intended to justify the jimmy choo theory of general intelligence. Thurstonc endorsed the equations but not Spearman's theory ofg. He agreed with Godfrey Thompson who had shown that even when the reebok zigtech tetrad differences arc essentially zero, there arc legitimate alternative explanations that involve multiple factors instead of £.
By 1947 Thurstonc scenis manolo blahnik shoes to have become friendlier lo Spearman's theory: "It seems likely llut a sccond-otdct general factor, determined from correlated pri¬maries. may easytone turn out lo be reebok easytone Spearman's general intellective factor R." (ThursU>nc. 1947. p. viii)
Thus, while appearing initially lo have questioned the construct of general intelli¬gence—or ccrtainlv the evidence for it—he zigtech later became more acccpting of reebok reebok zigtech g if it was conceived to be divisible into oblique primary factors.
MY ASSOCIATION WITH THURSTONE
As a PhD student at Stanford. I wrote to Thurstonc in 1949 to ask reebok easy tone whether, were I reebok zig pulse to be awarded a National Research Council (NRC) postdoctoral fellow ship. I could reebok shoes spend a year working with him at Chicago. He wrote back saying "yes," thereby allowing me to propose that activity in my application lo the NRC In the spring of 1950.1 was completing my dissertation and w as pondering job offers from Harvard as an instructor, and from both Kansas and Hawaii as assistant professor. Although each of these differed distinctly from the others. I had little enthusiasm for any of them. A letter finally arrived from the NRC offering a fellowship award. Gratefully I accepted and moved lo Chicago to study with Thurstone in the company of several other postdoctoral fellows.
My manolo blahnik plan at Chicago was lo analyze data from the standardization of the 1937 Stanford-Binet intelligence lest, intending to develop oblique factor solutions, based on graphical transformations.Thurstone and I met weekly to review results from the graphs thai I created during the prior week, so lhal lie could advise me about fruitful next steps. I learned that he could anticipate far better than I the likely inlluenccs of a two-dimensional transformation on the simple structure for the other thidden > dimensions. Ills spatial-thinking skills were exceptional, as one would Reebok Shoes ex|>ec( from his lifelong reebok easy tone interots and competence in geometry.
In early 1951. Karl Holzingcr reebok offered a course on factor analysis in the College of Education. I intended to enroll in his course, but at the last moment decided to ask Professor Thurstone if. as the sponsor of my postdoctoral activities, that would be acceptable to him. reebok zig Willi a look of disbelief, he said, "Certainly, Jones, if you want to. bul you'll find it to be a total waste of time."1-'
Toward the end of the postdoctoral year. I was weighing faculty offers from Cornell. Johns Hopkins, and Michigan. Each was attractive and while puzzling over which lo accept, I was startled wlten Thurstone asked skechers shape ups me, "'Would you like to jimmy choo shoes join tin? faculty here?" I said. "Oh. yes indeed!" He and I then became faculty colleagues in 1951-1952.
