Black Genetics
Good reason exists to doubt whether genes advantage black Americans atsport as Jon Entine claims -- the phenomena of the birthday or age cut-offeffect. There is nothing genetic about being born in August rather thanSeptember but it can profoundly change the odds on becoming a professional footballer or tennis player [as well as being treated for mentalsub normality or dyslexia]. The cut-off effect shows that big populationdifferences need not be genetic since they can arise from apparently smallenvironmental ones. The mere existence of different numbers of blacks andwhite in a sport thus says nothing by itself about genetic advantage [thatrequires evidence of correlations between differences at the individuallevel between anatomy and physiological sport related traits and actualsporting success] -- dramatic population differences could equally be dueto apparently insignificant environment factors such as date of birth.For example, in the English FA premier league over twice as many players, 285 are born in the three months Sept-Nov as the earlier three Jun-Aug, 136. Gene wise they are the same. In a similar way, the Dutch tennis yearstarts from the beginning of the calendar year: half its young leag
The same effect occurs for reading and learning problems and could causeavoidable educational failure (Bell & Daniels, 1990; Williams, Davies, Evans & Ferguson, 1970). Individuals in a groupcannot all succeed or all failure. Beliefs about self-efficacy as Albert Bandura has shown strongly effectwhat we achieve see Bandura, A. Any problems will magnify as they fall further and furtherbehind. Expectations, after all, about what an individual can do and cannot do haveprofound effects upon their determination and persistence in such things astraining and so shape in a self-fulfilling way judgements made about whatthey can do -- and with that the opportunities to further develop them. At the start of infant school, a child born onAugust 31 will be in with kids born the previous September 1 --at their agenearly a quarter of a life older. ueplayers between 12 and 16 are born in the three months January to March (Dudlink, 1994; Edwards, 1994). Thoughsmall, such an effect -- as with month age -- could self amplify itselfresulting in profound statistic effects as the population level.
