I propose a novel local, non-relational single-world, non-collapse, non-superdeterministic/non-retrocausal (interpretation of) quantum theory called Environmental Determinacy-based or EnD Quantum Theory (EnDQT). In contrast to some quantum theories, EnDQT is not in tension with relativity and provides a local causal explanation of Bell correlations. Additionally, unlike collapse theories, in principle, arbitrary systems can be placed in a superposition for an arbitrary amount of time. Furthermore, it provides a series of novel empirical posits that may distinguish it from other quantum theories. According to EnDQT, some systems acquire determinate values at some point in time, and the capacity to give rise to determinate values through interactions propagates to other systems in spacetime via local interactions. This process can be represented via certain networks. When there is isolation from the rest of the systems that belong to these networks, such as inside the friend’s isolated lab in the extended Wigner’s friend scenarios, indeterminate values non-relationally arise inside.
