Occam’s Razor states that when offered competing solutions, one should prefer the simplest explanation consistent with the available evidence.
In it’s Newtonian version this is:
“We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.”
Or, more simply:
“when you have two competing theories that make exactly the same predictions, the simpler one is the better”.
Might I propose a political corollary, inspired by the Conservative Party ‘Strategy’ in Eastleigh?
“When seeking explanations for the behaviour of your political opponents, assume, until evidence suggests otherwise,that they are making incorrect decisions based on incomplete and inaccurate information in an atmosphere of barely suppressed panic. This is, after all, what you usually witness among those you agree with”.
This is, of course, a refinement of Conquest’s Third Law.
