Assume that study after study finds that the average correlation between global competence and employee productivity is r$(145)=\mathrm{.}4,$ p $<\mathrm{.}001.$ Based on this finding and the amount of variance that is shared between the two variables, should we only hire managers that are found to be high in global competence? Why or why not and can we assume that training individuals to be higher in global competence will cause productivity to increase in our organization?
