Just another example of the fact the Psychology/Physchiatry/Sociology are not SCIENCES. Are all uncoordinated people 'nerds'? Obviously not, go no further than any physical study on humans. Good intelligence and coordination are rare talents to begin with. Maybe it is just rare that a person has both. Thus the stereotypes: dumb jocks and clumsy nerds. I have a BSc in CSc. I can play baseball and number of other sports. I don't consider myself an exceedingly well coordinated person but I have competed at the varsity level in level in squash. I view this as another soon to be discounted psychological theory. Rain man.
