An axiomatic limitation on the deterministic scope required for superdeterminism and its consequentially greater likelihood

By positing a universe where all events are determined by initial conditions, superdeterminism as conceded by Bell frames correlations observed in quantum measurements as the consequence of an inherently predetermined cosmic order that shapes even our experimental choices. I use an axiomatic formulation of superdeterminism to demonstrate that Bell overstated the scope of determinism required. Assuming only the existence of a universe containing observers, I show that determinism in just the observer scope is sufficient. I then discuss how this sufficiency increases the theory's plausibility and suggest a path to its integration with results from other disciplines.
