We must warn the reader about another semantic confusion which has caused error and controversy in probability theory for many decades. It would be quite wrong and misleading to call
g(f)
the ‘posterior distribution off
’, because that verbiage would imply to the unwary that f itself is varying and is ‘distributed’ in some way. This would be another form of the mind projection fallacy, confusing reality with a state of knowledge about reality. In the problem we are discussing,f
is simply an unknown constant parameter; what is ‘distributed’ is not the parameter, but the probability. Use of the terminology ‘probability distribution forf
’ will be followed, in order to emphasize this constantly.Of course, nothing in probability theory forbids us to consider the possibility that
f
might vary with time or with circumstance; indeed, probability theory enables us to analyze that case fully, as we shall see later. But then we should recognize that we are considering a different problem than the one
