  Bell inequalities are a consequence of measurement incompatibility (not, as
generally thought, of nonlocality). In classical terms, this is equivalent to
contextuality -- measurement devices do have a significant effect. Contextual
models are reasonable in classical physics, which always took the view that we
ignore measurement devices whenever possible, but if that isn't good enough
then we do have to model measurement devices. It is also argued that quantum
theory should only be taken with counterfactual seriousness, because
measurement incompatibility is a counterfactual concept.
