Reading this, I looked up Bayes' theorem in my Probability Theory book, and
under the theorem itself, it was written: "Never has any theorem been
misused so much my so many".
I fail to see why anyone would hold this theorem so highly that he writes
poetry about it. In fact, I do not really think that you (Eli) really
understand the theorem. For instance, this example is given in my book on
elementary probability theory as a direct application of Bayes Th.:
In a land there lives two kinds of people: X and Y. Among the X:s, 80% are
tall. Among the Y:s, 1% are tall. The population in this country is 10% X:s
and 90% Y:s.
A tourist randomly meets a person, who happens to be tall. Use Bayes'
theorem to calculate the probability that this person is an X.
Can you (Eli) solve it? It ought not be a problem for someone who can "see
the BPT flowing underneath the surface of all cognition, like blood beneath
