  We show that Bell inequalities can be violated in the macroscopic world.
  The macroworld violation is illustrated using an example involving
  connected vessels
  of water.  We show that whether the
  violation of inequalities occurs in the microworld or in the macroworld, it
  is the
  identification of nonidentical events that plays a crucial role.
  Specifically, we
  prove that if nonidentical events are consistently differentiated,
  Bell-type Pitowsky inequalities are no longer
  violated, even for Bohm's example of two entangled spin 1/2 quantum
  particles. We show how Bell inequalities can be
  violated in cognition, specifically in the
  relationship between abstract concepts and specific instances of these
  concepts. This supports the hypothesis that
  genuine quantum structure exists in the mind. We introduce a model where
  the amount of nonlocality and the degree of
  quantum uncertainty are parameterized, and demonstrate that increasing
  nonlocality increases the degree of violation, while
  increasing quantum uncertainty decreases the degree of violation.
