*Well, I wouldn't necessarily say "most" of the time, but I
  would say "some" of the time, yes. There's the N400. There's a
  moment of choice - always a moment of choice when faced with
  novel input.

  I"m not speaking of patterns - scripts people play, habituated
  behaviors. That's known and easily manipulated. I could write
  books on that alone. It's one of my favorite topics, especially
  when the linkup to the monomyth and how influential that is in
  the way we frame our existences as "stories" and such.

  Myself, I've been in a process of stripping away the stories,
  only to find more stories to be stripped away and taken into
  account.

  So yes, they're real Influencers: When we're running on
  automatic, playing our roles as it were.

  BUT: barring tangible, biochemical pathway issues, is there free
  will?

  Yes, there is. A moment of clarity. There can be many moments of
  clarity with practice.*

  It's still in there. It's never gone - just hiding perhaps. It's
  easier to play the scripts.   Did I share this yet?

  metaphors. I believe we are led and misled and in fact do much
  of our learning (if not all) via metaphors overlaying on
  metaphors. So much so that we often misplace the originals but
  they're still there.

  To me, the fact that there *are* manipulation machines, doesn't
  take away free will existing.
