Harvard professor Henry Louis Gates' arrest has given new life to the issue of racial profiling. We can think of profiling in general as a practice where people use an observable or known physical attribute as a proxy or estimator of some other unobservable or unknown attribute. Race or sex profiling is simply the use of race or sex as that estimator. Profiling represents mankind's attempt to cope with information cost. God would not have to profile, since God is all-knowing. Published August 22, 2009
