Touche - the prediction mechanism, the event, then the
  Inhibition before the N400 then the N400.*

  It's true, we're never "in" the present moment. Quite impossible
  due to our machinery.*

  I tend towards seeing these kinds of things as hysteresis; and
  the lag is critical to take into account.

  But let's consider the anticipation-based-on-past-inputs/the
  action/the inhibition/the n400 "circuit" as a single processing
  unit.

  I still don't see how the existence of the lag invalidates free
  will. We make changes to resolve cognitive dissonance, either to
  our outer environment or to our "inner" environment. [try to
  change what's around us, or restructuring our beliefs/ideas in
  some fashion] generally... yet we also hold contradictory
  beliefs simultaneously with ease most of the time.

  The thing about this: It all makes sense. I see us as state
  machines - anticipation machines; driving through life
  experiencing Time as if driving forward while looking backwards
  and SHOCKED when a rock comes crashing through the mirror which
  we thought was a window...

  ... yet it doesn't, for me, invalidate free will.

  In short, it's a nice story to conclude there's no free will
  except the sociological consequences would be absolutely
  dreadful should a society decide en masse that "yes, there is no
  free will". Courts? Poof gone. Reasoning? Why bother?

  To me, since we CAN'T PREDICT with any sort of accuracy all
  possible choices of a person, it's far TOO SOON to declare free
  will doesn't exist.*

  I couldn't recommend to anyone that we have no free will because
  all of these subtle nuances will be completely lost on most
  people, even if explained.

  It would be disasterous for a society to believe they have no
  free will. Dreadful.*

  Also, you have to consider that it is the VERY SAME supposedly
  determinate systems that built the machines to measure the lag
  to provide the determination that we have no free will.*

  I still content that "there is no free will" is an interesting
  fairy tale backed by a nice story filled with neural circuitry
  measured in laboratory conditions isolated from reality.

  We do not know enough about the brain for this level of
  certainty. It remains a fairy tale to my ears, one that is
  somewhat inspirational and freeing, but a story nonetheless.
  Certainty is also an illusion. It is an emotional state. Reason
  is an illusion for the same reason. Can't have reason without an
  emotional push. Yet we still have to act 'as if' these things
  are true, just as we have to act 'as if' free will is true
  because from a pragmatic perspective, it's true. The
  distinctions only need come into play in certain circumstances.
  Apologies for bringing seemingly unrelated things into it. It's
  a subject I'm passionate about because overconfidence in a
  deterministic Universe is a very bad thing.
