The absolute best it can possibly do in an ideal situation will only ever be as good as insurance actuaries predicting which clients will suffer losses and make claims. This is dubious enough on its own.Based on what I've heard profiling is charitably educated guesswork based on the law of averages within the confines of the case they're on. So a step up from pure quackery like phrenology but more in line with throwing darts at the idea board.
