Steve, your problem is in the idea that probabilistic has any meaning
when applied to an individual. It doesn't. You might respond that if
you average the prediction of several individuals you will tend to be
correct. At that point, you don't have an individual, you have a
statistical sample.
Sit down sometime and calculate the standard deviation for a sample size
of one, then think about what that means.
