Blacks and Jews

Our attention will turn, below, to the environmental side of the etiological ledger, never entirely—impossible to do so—with a blind eye to the other side of the coin. Thus here we dwell on a sign of the role of heredity in the genesis of NTD, racial and ethnic tendency, and its persistence. There are examples of ancestral tendencies being diluted generation by generation (e.g. in Boston, Australia, and French Canada), but that seems not to have been the case with blacks and Ashkenazic Jews wherever they removed or were removed to. We go first to blacks and return to Jews below.
