By analogy, membership in a group that is more or less enfranchised than another could be seen as a Bayesian classification, while "race == power" is more Boole

By analogy, membership in a group that is more or less enfranchised than another could be seen as a Bayesian classification, while "race == power" is more Boolean. One describes a tendency; the other asserts an identity relationship. It doesn't map perfectly, but it's close enough for the bandwidth I have to keep contributing to this thread right now.
