Applying everyday language to mathematical results can be a tricky business.
Much of the confusion about Bell's inequality stems from errors of this type.
Bell's inequality will never be violated in a universe in which events
separated by space-like intervals never influence each other. Quantum
mechanics implys the inequality is violated. It is not violated in a way
that the influence is detectable *at the time it occurs* or in a way that
allows a signal to be sent. However space-like separated events are predicted
to *influence* each other instantaneously and this influence is detectable
at a later time.
