Complexity Theory

I’ve heard about Complexity Theory. It sounds like reductionism to me, though I’m told I’m wrong there. Dwelling somewhere between chaos and determinism, complexity theory seems, perhaps nobly, to be trying to understand the structure or natural laws governing the existential balance between chance and order. It seems a bit like divining the principles of an engineered universe. And certainly there are things that seem very highly engineered, in physics for example, positively deterministic systems, until we encounter quantum mechanics. Then our understanding is pushed perilously close to chaos. The weakness in seeking an understanding to predictable outcomes for highly complex events is the somewhat quantum nature of the causal agents, you and me. We defy reductive reasoning.

If reductive reasoning presumes that the complexity of a thing can be defined or reduced to a single cause or formula, its logic hangs on causal networks that are patterned or replicable in some way. If the exact same state exists in all aspects, then the exact same effects will descend from a single causal event. Expanding the cause to a set of causal states, changes little. There are two possible shortcomings in this theory, which do not falsify it, but may certainly dilute if not neutralize it.

The first is an easy shortcoming to predict: the exact same state existing in all aspects. This is an extremely improbable, if even vaguely possible occurrence. If the universe began with a big bang or has always exist, with our understanding of it deriving from passing through time and space, then, whether or not it is progressing, it is always changing as we see it. Therefore, we have already passed through the time and place where things were as they were, and can never pass through that time and place again, we assume. Even if we were there again—and there’s no reason to doubt that that ‘there and then’ with us in it hasn’t, doesn’t and won’t always exist—it would still be the only time and place where “the exact same state [is] existing in all aspects.” So much for exactness; what about similarity?

There is promise of usefulness in this notion of reductionism at a less exacting level. The weather forecast is based on gathering aspects of climatology patterns, on which meteorologists’ computers, applying algorithms based on past results of similar states, can predict the probability of a range of outcomes. The forces of the irrational deterministic world seem pretty well subject to the reductionist theory. But what about the rational world?

The second shortcoming is degree of predictability on non-deterministic events. First of all, in human interactions, past data of the specificity needed to formulate reasonably reliable algorithms may not very well exist. Take for example the cases of Iraq, Libya and Syria. How much critical data can be collected from the first two situations from which to predict a reliable pattern for events as outcomes of the third? In the first place, there was only the slightest number of aspects in Iraq and Libya to call them so much as similar, and Syria shares an even smaller number with both. And it hardly matters how many conflicts we examine, in comparison with the more than 30,000 days of weather data from which to draw positive probabilities. We get what amounts to a weak guess of the final outcome. What’s more, weather is highly regular in its patterns due to our solar cycles compared with human events that have a slight daily and annual pattern and a life cycle. None of these cycles are very regular, especially in a world of global, continuous communications.

The second shortcoming is also subject to rational disruption. Reductive reasoning can easily be applied to poker; there are a known number of cards of each value in the deck and in play. The game is pure chance, except that players fold and bluff, rationally disrupting the course of chance. Even if we come up with reasonably reliable predictors of probability for massively complex human events, or even for our own life events, we will always have to deal with the folding and bluffing of other players in the guessing games of life.

Perhaps I will be proved wrong. Maybe people are changing. I have always found one pattern of complex human behavior to be consistent: the more we learn of history, the more we know how little we’ve learned from history—the  more we see that history simply repeats itself. The meteorologists don’t change the weather either. Makes ya’ wonder, doesn’t it
