the verdict
SUPPORTED
the evidence backs this
confidence 75/100
Classical electrodynamics and relativistic wave equations such as the Dirac equation canonically predict a gyromagnetic ratio of g = 2 for spin-1/2 particles, a foundational baseline against which small quantum electrodynamic anomalies are measured.
