Notice how the NE Asian countries fall in the upper right part of the
graph, while the African countries fall in the bottom left?
And notice the residuals, how correlation is not 100 etc.. In some
cases there is tremendous amount of potential left to be realized
(e.g. China). In other cases, rich natural resources matter, and in
the case of Qatar, thrust even borderline retarded countries into the
limelight (e.g. Qatar with only an IQ of 78, see top circular
datapoint)
