Exchange Symmetry
 
Exchange symmetry is derived from a fundamental postulate of quantum statistics, which states that no observable physical quantity should change after exchanging two identical particles. It states that because all observables are proportional to ψ2 for a system of identical particles, the wave function ψ must either remain the same or change sign upon such an exchange.
