=== Z2 Statements ===

In the future, there may be a category of Z2 Statements, which group Z Items into such things as agreed-on physical laws in the same way S2 Statements group S Items into hypothetical propositions. A Z2 Statement is not always to be taken as undeniably true and never to be falsified, but it should have a certain level of verifiability such that it is easy for multiple people in different parts of the world to demonstrate that it is at least partly true. A physics equation could be expressed in a Z2 Statement. At this time in history most claims in Marxism should not be Z2 Statements, although for a few especially-repeatable observations there could be exceptions. "Bolshevism generally instantiates itself in the form of a nation-state" might or might not be an acceptable Z2 Statement — this statement has always been observed to be true, and yet, it has exactly the form of a statement which could contain a black swan fallacy.
