I can remember a WPR a while back where only 3 people entered, so the pendulum can swing both ways. A "golden mean" is needed; where does it lie? As Plato wrote:
"Well, then, if we cannot capture the good in one form, we will have to take hold of it in a conjunction of three: beauty, proportion and truth. Let us affirm that these should by right be treated as a unity and be held responsible for what is in the mixture, for goodness is what makes the mixture good in itself."
So that pretty much clears it up.
