I didn't think of it as a need, but rather an imperfection in our evolution -
after all evolutionary adaption is a rough process and far from efficient.  I
thought of this in relation to the measurement problem in QM.  Under the
de-coherence theory of quantum measurement, the wave function doesn't collapse
it continues it's unitary development but the interaction with the macroscopic
environment causes the density matrix to become practically diagonal.  We don't
perceive the very complex wave function that still encodes the pre-measurement
coherence - even though in principle it's observable.  Why? Maybe, because it would
not be evolutionarily favorable to perceive these coherences.  It would be like
seeing wabbits; but not really since these coherent but complex wave functions are
part of standard physics.  It is more like seeing Schrodingers cat.
