 The scientific evidence for quantum mechanics is sometimes said to show that determinism is false. Quantum theory is indeed very well confirmed. However, there is nothing approaching a consensus on how to interpret it. Indeterministic as well as deterministic interpretations have been developed, but it is far from clear whether any of the existing interpretations is correct. (For a more in depth discussion of rival interpretations of quantum mechanics see section 4.4 of the Determinism entry.) Perhaps the best that can be said here is that there is currently no good evidence that determinism is true.
