Nature & Technology
Unintended Consequences - Wexelblat's Law
Interview with Alan Wexelblat, Ph.D.
Alan Wexelblat, Ph.D.
with David W. Alvey, Executive Director and Editor - Diplomatic Planet
Introduction - Joel Garreau as a teacher, journalist, author and lecturer
is well versed in looking at cultural revolutions and public policy. In his
Washington Post article on September 2nd, 2001 "Nature's Revenge - Our Planet
Has a Cure for Arrogance: It Makes Technology Into Our Enemy", Garreau looked
at disaster from the perspective of "Nature's Revenge" and the "Law of Unintended
Consequences".
Dr. Alan Wexelblat has been an observer-chronicler of the emerging pattern
of disasters that result from Nature's vagaries and our own actions' "Unintended
Consequences". Wexelblat's Law is wryly expressed as "When it comes to
technological arrogance, nature has a nasty sense of humor". The resulting
disasters - natural events that become magnified with effects that have
unexpected large-scale impact on our man-made systems and our lives - can
be attributed to the overload on Nature and the overexploitation or
disintegration of a layer of relationships within its complex, inter-related
network.
These twisted actions with dire consequences are called "Wexelblat Disasters"
in (ahem) honor of the efforts of Alan Wexelblat who has popularized awareness
of such events - as he, and we, look for signs of these long term, gradual
shifts that build up consequences much as heavy flood waters can build up
behind a dam. We see the water levels rise in the reservoir, but do we see
the new channels being cut back upstream that will eventually circle around
the dam, or the minute cracks in the dam walls that are straining and nearing
collapse?
Our Disruptive Nature Finds the Weakness!
Integrating the human system into nature and the gradual build up of the
consequences of our actions, per Garreau, fascinates Wexelblat - "Two trains
banging into each other are dramatic. But the fact that the land is shifting
and the rails are moving is harder to see". As further described by Garreau:
"It's not the lightning that electrocutes you, it's the wire it knocks down.
It's not the heavy soggy topsoil that gets you, it's the fireball from the
ruptured underground gasoline tank.
It's not the floods that get you, or even the floods levitating the house
off its foundation, it's the natural gas leak when the pipes break."
On September 12, 2001, the day after commercial airliners became adulterated
tools of terror - I went back and re-read Garreau's article for its corollary
on express human causes of techno disasters. Obviously, the actual domino-like
calamitous consequences of the planes and their jet fuel bombs were not
predictable events by these mass-murderers. A best ("worst") case scenario
might have been for them to slice off a corner of a building, topple a wedge
of the building, and to have a fire rage through the floors above. The results
achieved - to take out the shell and the wall of structural supports coupled
with the fierce intensity of the fire to cause both buildings to implode
- becomes fantastic guesswork that could not possibly be directed or designed.
Dr. Wexelblat earned his doctorate at MIT's Media Lab where he designed and
studied systems (sometimes called Community Support Systems or Digital Ecologies)
to help people achieve working partnerships among themselves and with machines.
Per Dr. Wexelblat: "The basic notion is that you have a group of people,
probably dispersed in space and time, who need assistance with an
information-related task (search, browsing, navigation, retrieval,
recommendation) and they turn over part of this task to computer systems
that help them by finding, organizing, and recommending knowledge sources,
including other people."
DPlanet: Dr. Wexelblat, am I reaching too far to relate "Nature's Revenge"
and the "Law of Unintended Consequences" to the recent disaster at the World
Trade Center in New York? Do those general issues of using common and benign
technology to disrupt apply as we assess this entire scene?
Dr. Wexelblat:
I think there are two phenomena at work here.
One is best labeled as William Gibson put it in his mid-80s cyberpunk novels:
the street finds its own uses for things. That is, given a device or system,
the users of that device or system will adapt it to the purposes they have
in mind, without regard for the intentions of the system
designers/implementers/maintainers.
A good low-technology example: in Brazil, the phone company kept finding
that the handsets were torn off its public phones. The reason turned out
to be that someone had discovered that if you hooked up these handsets to
a car battery and put it in the water it would emit tones that were very
attractive to the kinds of fish that these fishermen wished to catch.
A more high-tech example of this is email. Supposedly designed just to carry
messages it has now become a primary means of file transport (via attachments)
of data storage (via people keeping large email inboxes or files of past
email) and of spreading destruction (via the numerous Outlook viruses and
worms of the past few years).
The second phenomenon is sometimes called the "Law of Unintended Consequences."
This happens when large effort is exerted towards one effect, but a second
effect happens - often opposite to what you desire.
It is my opinion that this "law" comes into play most often when people use
technological systems, or legal systems, to try and enforce social change
or policy (domestic or foreign). Two recent examples are these:
Recently, freelance writers sued over copyrights for their articles in online
databases. In particular, the New York Times was a defendant, but the goal
was to establish a US nation-wide legal precedent. The goal was to force
these publications (such as the New York Times) to pay royalties for publication
of the freelance articles. The writers won, but the unintended consequence
was that the New York Times refused to pay and simply stripped all freelancers'
articles out of its online database.
Sadly, I fear that Osama bin Laden is an example of this same law. Our intention
was to "contain" or "protect the world from" communism. In doing so we created,
trained, and financed radical Islamic extremists who first turned to the
production of heroin to finance their activities and, starting in about 1983
with the attacks on our troops in Lebanon, have now turned to massively bloody
acts of terrorism against us.
The key difference I see is that the first kind of effect isn't really easily
predictable. The second is, or should be. We need to focus not simply on
achieving our goals but on doing so in ways that minimize the chances of
unintended consequences arising.
DPlanet: Looking at evil intent and direct consequences - is there a logic
to or a difference in strategy between attacking the hardware - denial of
service attacks, disconnecting server clusters or telecom junctions - versus
attacking the information and intellectual property itself - flooding sites
with bogus info, wrapping propaganda in mainstream formats, or deleting en
masse corporations and their workers?
Our limited experience in the types of losses that many of the companies
resident in the World Trade Towers have experienced - where they have lost
their institutional data files and the key personnel who represent the
relationships and the institutional memory and practices - would suggest
that most of these companies will fold within the next three years in addition
to those that will not re open or will quickly go into bankruptcy. Also,
within the context of your interest in the effects of slow, less loud shifts
in nature - Should we be more aware of this paradigm shift as we view our
technology and its abilities to become destructive and disruptive of nature
and its penchant to compound the natural consequences of weather, gravity,
building cities near rivers and coastlines, clusterings of intellectual property,
etc.?
Dr. Wexelblat:
I'm not sure these are comparable. It seems to me there are fundamental
differences in kind, not merely in scale.
The fact of the matter is that the attacks on the World Trade Center towers
were astonishingly low-technology. The weapons used - box cutters and small
knives - could not have been stopped without banning all carry-on luggage
and body-searching all passengers. Even then, ground crew servicing the airplanes
could have been subverted to plant such weapons for later use.
What strikes me as sui generis in this case is that the "rules of the game"
have changed. I simply don't see any successful hijack scenarios occurring
in the future, because all air passengers now have been forced to realize
that they may not get out safely and indeed their lives may be taken in the
course of massive destruction.
The apparent downing of the UAL flight over PA as a possible consequence
of passenger action shows us the likely course of future attempted hijackings
of passenger craft. If we had wanted to prevent such a scenario the methods
were well known before 9/11. El Al has an aggressive "air marshals" program
coupled with reinforced airplane cockpits and training that the pilots must
not leave the cabin while the passengers are on board. Boarding an El Al
plane only happens after extensive luggage searches and intense questioning
from motivated employees.
As a result it costs more to fly on El Al, but they don't get hijacked. In
the US we turned airport and airplane security over to the airlines themselves.
These corporations are legally bound to maximize their value to stockholders.
Providing high levels of security was too expensive and it simply wasn't
done. Security personnel at airports make something like $5.75 per hour,
less than some people working at McDonald's. Some low-price airlines pay
their pilots only $15,000-30,000 per year.
It is not hard to look at this and see how the law of unintended consequences
has come to haunt us. Goal: cheap air travel; unintended consequence: severe
vulnerability to terrorism.
If we wish to avoid this kind of thing happening in the future, we must look
for such consequences. For example, if one consequence is a new willingness
of airline passengers to fight hijackers to the death, then it is only logical
to look for cases where a future hijacker could commandeer a similar plane
without risking an aggressive hostile response from passengers.
To me this suggests cargo planes, such as the fleets operated by FedEx, UPS,
and so on. If I was in charge of national transportation I would be insisting
on massive increases in security on such planes, background checks on all
employees, and much tighter screening of cargo loaded into such planes. It
doesn't take genius-level imagination to see that once in control of a cargo
plane a terrorist could remove the benign cargo and load it up with explosives,
such as the so-called fertilizer bomb used in Oklahoma City.
With that said, I do think there is a relationship between technology, technology
analysis, and our response to these acts of aggression. Joel Garreau, who
first interviewed me, has a very thoughtful piece in the Washington Post
"Disconnect the Dots - Maybe We Can't Cut Off Terror's Head, but We Can Take
Out Its Nodes" (2001-Sept-16) on using network analysis and network-disabling
attacks against terrorist groups.
As to slow shifts in nature -- I think the sad context here is that we are
forever fighting the last war, or countering the previous paradigm. Sailing
aircraft carrier groups to Afghanistan is what I would call a "Maginot Line"
response to these acts. We need to stop responding as if we were still fighting
the last war and start responding as if we wanted to fight the next one.
Note that I do not say "win" because I think the old concepts of win and
lose are not applicable here. We are in need of adapting some of the thinking
that goes into designing systems in harmony with long-term shifts. We must
design flexible responses, adaptive responses, and anticipatory responses.
Having a US President standing up there saying we will "win" this "war" is
as discouraging as it is absurd. Neither term applies to this situation.
The kind of thinking I think is needed to combat climate-change crises can
also be applied to these kinds of situations.
DPlanet: You have expertise in looking at information management - searching
for and accessing the needed information from the internet - and also in
the security issues of privacy and shared access that also apply to the internet.
How will the fundamentals of access across the internet or the rules for
personal privacy change as a result of these events - the unintended
consequences?
Dr. Wexelblat:
I don't think the rules for personal privacy will change as a result of this
event, except minorly at airports, where we've never had much in the way
of privacy anyway. I've heard some pretty silly things in the last week,
including airlines banning open beverage containers and requiring ID for
infants. I confess I have a hard time seeing my 16-month-old taking control
of a plane and I'm not at all sure how it helps anyone to hassle parents.
I also don't think the fundamentals of access online will change. The FBI
will get more power to snoop into our lives. People will conveniently forget
that the FBi and the CIA were not reigned in capriciously. They were reigned
in because when unfettered they did more harm than good, both at home and
abroad.
I continue to stress that this was a low-tech attack. CNN is now reporting
that bin Laden has thrown away his cell phones, pagers, and other high-tech
gadgets. They're irrelevant to him. I don't understand why this point doesn't
penetrate to people.
DPlanet: Do we have to work from a vulnerability mind-set?
Dr. Wexelblat:
Do you mean in the physical world or on the 'net? In both worlds we are
vulnerable. While we discuss this, a new worm (currently being called W32.nimda)
is busily wreaking havoc across the servers of corporate America. Like the
airlines, these financially oriented entities have decided that real security
is too complex and too costly. So they continue to be vulnerable.
DPlanet: How do we lock the cabin doors on the internet?
Dr. Wexelblat:
That's a cute metaphor but I don't think it's applicable. The Net far more
resembles bin Laden's organization than it does an aircraft. The net is
distributed, with some key nodes and massive redundancy. The story about
it being designed to survive a nuclear attack is apocryphal, but nevertheless
the Net has proven its resiliency against forms of attack ranging from
distributed denial of service storms to misplaced backhoes.
DPlanet: Do we widen the digital divide by creating separate, multiple "virtual
private networks" with very controlled entry and exits points and access
levels?
Dr. Wexelblat:
This already exists. In the small, most corporations have VPNs already. Internet
2 is well underway, with strict access rules. The Web population has done
a fabulous job of segregating itself already, with the top 100 or so sites
absorbing a huge percentage of the traffic. None of this has anything to
do with last week.
DPlanet: Does the communal internet have to die? Do we want financial transaction
electrons roaring along the same optic routes as my email to you? Do we pull
the plug on almost everyone so that same information route cannot be used
from inside a terrorist's bunker?
Dr. Wexelblat:
No, yes, and no. In that order.
Terrorists don't inhabit bunkers, except on those rare days when someone
is shelling them. They walk the same streets as you and I. They attend the
same colleges, the same flight schools, sit in the same parks, and fly from
the same airports. A mentality that says we can draw a line in the physical
world and somehow put "them" on the other side from "us" is a fantasy.
Given that, there is no conceivable means by which the terrorists can be
restricted from the 'net either. All we could do is cripple our most powerful
recent engine of information freedom and economic progress.
DPlanet: Is it heresy to now say that we rely too much on technology?
Dr. Wexelblat:
Of course not. Many people have been saying this in many forms for a very
long time.
DPlanet: I am sure that many people are looking at airport security procedures
and saying - "Why didn't the computer pick up the fact that there were four
middle eastern men paying for one-way tickets with cash at the gate - and
trigger some warning?" Are we that technology sophisticated?
Dr. Wexelblat:
Again, there is a fallacious assumption here that somehow evildoers will
kindly tattoo a mark on their foreheads or on their financial records that
will allow us to identify them so we can draw that nice safe line separating
us from them.
I'm sure these people all used credit cards, just like you and I. I bet they
even had good credit histories, just like you and I. I'm sure they bought
round-trip tickets, just like you and I.
This is the fallacy underlying so-called profiling, which used to be called
"racial profiling" before someone realized that was a big stupid flag to
march under. People are not statistics, and attempting to reduce the general
to the personal leads to egregious errors and intrusions. Profiling has been
a consistent failure every place it has been used.
DPlanet: Alternatively - Do we want "Big Brother" intrusions to take over
human interaction and assessment? "Well, that's procedure!" -- By relying
on a computer print out to challenge someone anonymously - what are we saying
about the individual, culture and ethics?
Dr. Wexelblat:
Quite a bit, and much more than I have time and space to answer here. I will
just point out that this is the normal state of affairs now. Again, I don't
see massive changes coming about after the tragedy of 9-11.
DPlanet: What have we abdicated? What are the new points of conflict between
inward looking self interest and outward looking self-expression?
Personal Freedoms versus Group Security?
Dr. Wexelblat:
The conflict between the personal good and the group good has always been
there. It's not a matter of chance that people consistently quote Ben Franklin
on this. It just takes different forms at different places and times. What
I think we've abdicated is the notion that anything other than the pursuit
of money is noble, worthy of protection, or available as a priority. If you
want to lay the blame for this at the feet of some god, lay it at Mammon's
feet.
"I don't mind an environment where the ability to better oneself is available
to all; what I find repugnant is that we consistently sacrifice all other
goods, from personal safety to national preservation to that one goal."
If you want to see the new points of conflict, go watch an IMF meeting or
G8 summit. The so-called leaders of the free world huddle in massive fortresses
or behind ranks of shoulder-to-shoulder cossacks and the (corporate) press
continues to report it as if nothing was amiss.
If you want to see the new points of conflict, go watch as a corporation
(Adobe) uses the national police force (FBI) to arrest a foreign national
(Sklyarov) for violating an absurd law (DCMA) when what he did wasn't even
illegal in the jurisdiction in which he did it.
For all the death, destruction, and tragedy bin Laden and his followers are
a drop of excrement on the buttock of the early 21st century. Aggrandizing
them, or attributing to them consequences that were already well underway
before he started running heroin, is just missing the point.
Bruce Sterling correctly pointed out that most ills of the present decade
will be attributed to what he called "The Four Horsemen of the Modern Apocalypse:
"
drug kingpins, international terrorists, hackers, and child
pornographers. bin Laden is just the most prominent example of one group.
DPlanet: Thank you. (DWA)
