Ethnic minorities have a built-in insoluble problem – the majority population will invariably resent their presence if the ethnic population is of a size which allows them to effectively colonise a territory – and that territory may be as small as a few streets – and to be visible as a distinct group.
Where this occurs the majority population will normally not feel any ethnic solidarity with the minority, while the ethnic minority will keep itself to itself. This will severely limit any assistance at the purely social level the majority gives to the ethnic minority populations. Where the minority is of a lower average IQ than the majority population they will not benefit from the help of the higher IQ majority in the same way that the lower IQ members of the high IQ majority are helped by higher IQ members of their own group.
The larger the minority group the more extreme its position will become, because the larger it is the easier it is for a member of the minority to live without having social inter-action with the majority population. This will make the majority population even less inclined to offer aid to members of the minority. As mentioned previously (see Welfare, Ethnicity and Altruism), there is also solid evidence that the more racial and ethnically divided a society is, the less willing are its members, and particularly those of the majority group, to provide for social goods such as welfare or healthcare.
Because the low IQ minority has inadequate access to aid from those with higher IQs, as a group they will display a disproportionately high level of antisocial behaviour because they are less able to cope with the practical and psychological demands of a high IQ society. Being a low performing minority in a high IQ society also feeds the paranoia and victimhood of the minority, who tend to attribute their failure to succeed in the society to oppression and discrimination by the majority. They will make this attribution even when other higher IQ minorities in the society do succeed.
A higher IQ minority amidst a lower IQ majority is a much rarer phenomenon. The examples involving black majority populations are mostly restricted to colonial situations, whether past or extant, the most notable example being South Africa which is kept afloat as the most advanced state in black Africa by the white created infrastructure and continuing large-scale white involvement in the country.
Minorities of Ashkenazi Jews and Asians in Western countries have higher average IQs than the societies in which they live, but there are two important differences between their position and the position of whites in SA and their majority black population. The first is the fact that the difference between Ashkenazi Jews and Asians and that of the white majority population is nothing like as great as that between blacks and whites. The second difference is that the white average IQ of 100 is adequate to create and sustain an advanced modern society.
