Lengthening the Feedback Loop: A History of Feedback Within the
Context of Systems Theory

Unfortunately, may be most interesting as an example of how
examinations of "the importance of feedback" are weaker in the absence
of perceptual control theory.

Thanks, Tracy. I skimmed it and I'll read it again more thoroughly. My
knee-jerk reaction is to coin a term: "pop feedback" (to go along with "pop
psychology"). She inadvertently endows "the market" with sentience which is
too much of a stretch for me. She also lays everything at Wiener's door (or
in his lap as the case may be). Oh well...as I have said for a long time
now, "Most feedback isn't..." Also, "Feedback isn't between you and me but
between my reference and what I see."

Yes, her attitude toward Wiener seems out of proportion with his
contribution to what she puts under examination.
Another flaw is the way she suggests that positive feedback can be
viewed as structural. The presence of such "feedback" makes a
difference, of course, but one of the basic lessons of PCT is that
positive feedback shows up mainly as an environmental factor, rather
than as a component which comprises portions of organized systems.
I must admit, I've only skimmed the piece as well.
