Information cannot be free

Information is an a widely misunderstood feature of modern society.
It is seen as absolute and objective, however, neither of these
are the case. As Shannon pointed out, the relationship between
information and noise is fundamentally paradoxial.
Shannon and the mathematics of information
I will offer the reader a short introduction to the work of Shannon.
Shannon was basically beset with the problem of designing error-free
transmission through a given physical medium (telephone wires).
What he discovered is that:
1) Information, or a messages percieved as informative content
ulitmately depends on the reciever. There is no objectively informative
message. For instance if a lecture is given by a American professor
on Economics, different information will be recieved by, for instance,
an english speaking Economics student, an english speaking Art
student, and a non english speaking person. The quality of the
information depends entirely on the formulations of the recipient.
2) The more information a sender attempts to pack into a message,
the more tendency it has to be percieved as noise. For instance,
acronyms are a popular way to con-dense a message. In example
the message: "NLP is a very hot field at this time."
If it were recieved by someone who had no idea what what Natural
Language Processing was (or Neuro-Linguistic programming) the
message would be meaningless noise- discarded by the perceptory
apparatus of the reciever. We are by no means limited by acronyms,
no real field of study would be possibly without this condensing
or abstracting mechanism.
3) The more redundancy a message contains, the more likelihood
that it will be recieved as information. This is a more complicated
phenomenon to illustrate in terms of literary messages. If you
are familiar with communication engineering, this can be illustrated
by the "checksum" value contained within every packet
or quantum of information. The checksum is used by the recipient
to make sure the information contained within is valid. If found
to be corrupt, it is discarded (and often the source is re-interrogated).
Geneticists believe that the highly redundant nature of our own
DNA is an example of this rule in effect.
Absolute information implies the absence of information
If you take the above principles to thier fullest extent, you
will likely begin to notice thier paradoxical nature. The more
information I attempt to send, the more potential for noise (anti-information
or entropy). The more I try to prevent noise, the less information
(redundancy is a lack of information, redundancy is the lack of
information) I encapsulate in the message.
Now this brings us to the issue of communication networks. It
seems that the thesis of "media engineering" is to allow
the so called "free flow of information" (the popular
hacker mantra). As I illustrated above , the complete free flow
of information would end up as noise (this is evident but conveniently
ignored by the hacker culture). It almost seems as if the proponents
of this theory believe that the so called "lies" or
false information would enevitably burn themselves off in some
kind of semiotic state-change, as if misinformation (which implies
deliberate falsification) were the product of the said obstruction
of the free flow of data. The meaning of "misinformation"
or lies is apparently not directly related to the structure of
communication. ("the truth can be found in a lie" :))
Censor is not a four letter word
If we accept the above terms, that the free flow of information
Is Not The Ideal, then of course we begin to contemplate the realm
of censorship. Censorship is not an altogether detrimental thing.
Even the most so-called liberal parties participate in the activity
of censorship. Without such selective limiting of data, there
would be no coherence, and therefore noise. In the most common
form of internet correspondance, the Listserv (or newsgroup),
the owners of the lists (whose motives range from artistic to
stricly commercial) have to constantly wrestle with the dynamic
of free-flow vs. censorship. In the former situation, we have
the inevitable "flame-war" an explosive sematic feedback
phenomenon, ultimately uncondusive to any kind of useful constructive
discourse. In the latter situation, we have nothing but data put
in-formation by the moderator, with no forum for interchange (this
is often a situation that is highly critisized).
Finally, the purpose of this essay is to dispell the popular
"information should be free" rubric, to show that our
reality is merely the interplay of these two forces: noise, and
information (or as termed in previous essays communication and
information). We cannot base social policies on this platform,
and it is utterly futile to try to realize it (Freenet, ect. ).
Often times, social inequality is blamed on the percieved obstruction
to the access to information. Social inequality, I hypothesize,
is based on other unknown factors (social inertia?).
