  Some of the strategies which have been put forward in order to deal with the
inconsistency between quantum mechanics and special relativity are examined.
The EPR correlations are discussed as a simple example of quantum mechanical
macroscopic effects with spacelike separation from their causes. It is shown
that they can be used to convey information, whose reliability can be estimated
by means of Bayes' theorem. Some of the current reasons advanced to deny that
quantum mechanics contradicts special relativity are refuted, and an historical
perspective is provided on the issue.
