Sewell has, foolishly, examined the concept of culture and that of academic interest out of the context of the environment and history of the groups of people concerned.
Culture is, in itself, the product of tradition, experience, beliefs, ability and facilities.
It should similarly be obvious that variables such as accumulated history, social climate, and presence as well as perception of academic opportunity, should be considered. How it is that Sewell has concluded that variable A leads to behavior B, without rigorous testing, is a mystery. The race, qualifications, previous achievements, or even personal experiences of a researcher have no relevance whatsoever or bearing on the validity of a suggested hypothesis. If research for the Commission for Racial Equality is undertaken in the flippant manner exemplified by Tony Sewell, there is little hope for those expected to benefit. All human beings are free agents, and although most engage in conformity, they do not do so without reason.
