Slashdot Mirror
On The Collapse of Complex Societies
One of the mailing lists that I'm on had a great short essay about the disastrous decision that societies can make - and their consequences. The author is Jared Diamond, who also wrote Guns, Germs and Steel (First Slashdot book review was that book), and is still one of the most interesting books I've read in a while.
Fisheries are being depleted around the planet. In each case that the problem is identified ahead of time, the local fishing industry mobilizes to prevent restrictions on their own fishing. They always find some other cause to blame for the loss of fish populations - in Japan, they blame it on whale protection laws; in the Maritime Provinces of Canada, they blamed it on environmental policies. In no case did they accept overfishing as responsible, until it was too late.
Now, the North Sea fisheries are facing the same threat. And predictably, the fishing industries their are in deep denial, insisting that quotas on fishing "threaten their way of life." A group of former fishers from New Brunswick actually travelled to the UK to testify that, in fact, it was quite conceivable that overfishing was responsible, and to beg the British fishing industry to not be as stupid as they had been.
I think this is the key to poor decision making in groups - it's group-delusion, strengthened by fear of challenging group consensus, and fed by short-term self-interest.
I read the book, and I didn't find any "butterfly effect"-style determinism in it. Diamond's explanations for why civilizations rise and fall seem perfectly sensible to me. Would you seriously suggest that a civilization that was lucky enough to rise in an area blessed with an order of magnitude greater arable land (Eurasia) than another (Australia) would have a harder time developing a leisure class, with its concomitant art and science? What might explain it, then? Racial superiority? Manifest destiny?
Guns, Germs, and Steel doesn't nitpick particular instances in history and say, "This is where everything else inevitably sprang from." Diamond's book simply says: People tend to go where food is. If there's enough food, they stay, forming a mass. Masses of people tend to interact in interesting ways, producing culture. Positive feedback loops tend to develop. Cultures that miss out on the effects of the feedback tend to be dominated in the future. That's a powerful enough set of axioms to explain a great deal of history, without being mechanistic enough that it claims to determine how history will unroll into the future. Note the emphasis on large-scale aggregations of humans, long time scales, large land areas, etc. in the book. No butterflies required. Plenty of room for free humans to try and leave their mark in history.
