I don't believe that is what is meant by "6 cents is what the human ear can
perceive".  

Maybe I'm totally wrong, but 5 or 6 cents of mistuning won't sound sour or off or
bad when played in an ensemble of other properly tuned instruments.  You'll hear
the phasing, even if it's different by 1 cent or less, but it won't sound like a
6th grade band concert.  In fact, I tune synth instruments or VCOs a teensy bit
off on purpose to get fatness.  Sometimes I tune them off more than 6 cents to
make it sound sour on purpose - if that's what the art I'm attempting demands. 
But regardless, I can hear it, and probably all of us here can.  

It may also have to do with pitch memory.  Play a note that is dead on.  Then play
one that is 5 cents off the previous note, with some seconds of silence in
between.  Can you tell the difference then?  Not sure, but I'd guess not if the
notes are close enough.  I'd also guess that everyone's threshhold of detection is
a little different.
