Occam's razor states that the simpler explanation tends to be correct. Is this merely heuristic or is there a metaphysical reason why it works so well in science?
Famous examples include Newton's explanation of planetary motion, the tides, and the fall of an apple by a single sweeping hypothesis, Darwin's explanation of the rich variety of life as descendents from a single common ancestor, and Copernicus' view that planets orbit the sun in roughly circular orbits.
Sometimes, ideas that violate Occam are the products of wishful thinking. With extreme vanity, man once believed all planets and the sun orbited the earth and invented many specious arguments to explain "retrograde" planetary motion.
The Biblical view that god created millions of species and their habitats separately flatters man's ego as being all for us, the lords over this extremely special creation.
"Tautological nihilism" attempts to explain the world without invoking any hypotheses, principles or substances.

If it explains the origin of the world as well as any other, should it be given preference by Occam? Is it reasonable to suppose that someday people will again conquer their vanity and accept such an unflattering view of man and nature as "zero sum nihilism" leaves us with? Bonus: no religion, therefore no more religious infighting.
If Occam has no exceptions, is it not rather difficult to argue that it is merely heuristic? Should we not therefore focus on explanations that obey Occam?

The answers so far show that people do not understand the razor. The razor is applied only when two or more testable explanations of the all of the data are possible and only when one is clearly simpler than another.
Copernicus' explanation and the Church's explanation fit the exact same planetary data. The Church's was needlessly complex because it hypothesized retrograde motions and provides no workable mechanism for such, and is thus rejected by the razor.
String theory makes no novel, useful or testable predictions and thus cannot possibly be an exception to Ockham. Its uselessness as a theory is a prime example of what happens in science when the razor is disregarded.
As far as Q.M. goes, give an example where two models accounted for all the data and the more complicated one won out over the simpler one.
The razor is also not applicable to literature. No one can explain Harry Potter's magic, which violates several conservation laws in physics, with the razor.

Sorry, this question is compounding confusion, rather than illuminating anything. When two or more models fit the data, a scientist cannot simply use Occam to test the "simpler" model. That would not eliminate the more complex model. He devises a test that decides between them and often notes the more complex model lost out, in accord with Occam.
No, Occam is not a truth serum. It is a test based on some ambiguous terms like "simpler," "all other things being equal" (when are they ever?), "explanation, " etc.
The statement that Occam is not as applicable to literature as science did not mean to exclude literary criticism, which is not literature. Plots and characters are rarely logical, as people do the strangest things and are illogically and irrationally motivated. Particles in physics may seem strange, but not compared to people. Simple explanations of human behavior like why Iago hated Othello are not the rule in literature and are ridiculed routinely in literary criticism.
