Today's NEW YORK TIMES contains an op-ed piece that refers to a study from
Northern Ireland in which Protestants outscored Catholics in IQ by the same
magic 15 points.  If this is drawn from credible research (credible in this
incredible context, of course), it would make for a useful debating point.
Does anyone know more about this?
