“ People who have made comparative studies of many different societies, know that when status is ascribed, rather than achieved, individual efforts towards excellence are not directed through any form of innovation; rather, the enhancement of status occurs only through the realisation of a previously well defined role position. It is only with social change, or when some form of continual dynamic disequilibium occurs in a society, that we begin to observe the development of achievement motivation in its modern form. ”
