We deduce the Born rule from a purely statistical take on quantum theory within minimalistic math-setup. No use is required of quantum postulates. One exploits only rudimentary quantum mathematics—a linear, not Hilbert’, vector space—and empirical notion of the
Statistical Length
of a state. Its statistical nature comes from the lab micro-events (detector-clicks) being formalized into the
C
-coefficients of quantum superpositions. We also comment that not only has the use not been made of quantum axioms (scalar-product, operators,
interpretations
, etc.), but that the involving thereof would be, in a sense, inconsistent when deriving the rule. In point of fact, the quadratic character of the statistical length, and even not (the ‘physics’ of) Born’s formula, represents a first step in constructing the mathematical structure we name the Hilbert space of quantum states.
