Systems thinking forms the way we think about peace. One example is the relationship between the free flow of information and a functioning government.

Systems theory

Systems theory originated while scientists were attempting to better understand the workings of organisms, such as cells or the human body.

Through such studies, it became clear that breaking subjects down into their constituent parts and using cause-and-effect thinking was inadequate to explain the operation of the whole.

The concept of linear causality

We imagine we live in a simple linear world where we feel we have to pick particular actions to alter the specific cause of a problem.

This is played out in many ways: doctors frequently look for localised causes of a disease; politicians get tough on crime; economists assume that shifts in one economic factor, such as an interest rate, can ‘explain’ everything that subsequently occurs.

The concept of linear causality is deeply embedded in our understanding of the world and the way we interact within it; it is built into our subconscious. We undertake an action and expect an outcome.

In the physical world the same actions always result in the same outcome. Throw a ball into the air and gravity will always cause it to fall at the same rate.

Ideas of cause and effect also appeal to us because they lead to the creation of apparently persuasive narratives or stories. Like stories, explanations of cause and effect are linear. A cause is like the beginning of a story, and an effect is like the end of a story.

The difficulty is that such an approach is partial and incomplete at best.

Examining Causality

Understanding the physical world through examining causality has enabled great strides in human progress. Modern empirical science arose because of it.

However, there are problems. Causality implies that all effects can be tracked back linearly to initial causes. The logical extension is that we live in a clockwork universe where the conditions are predetermined and there is no room for genuine novelty.

Causality is excellent for explaining discrete and well-isolated phenomena. But as we add more variables, the complexity expands exponentially. This makes attempts to isolate linear causal effects not just ineffective but potentially misleading.

The act of simplification destroys the integrity of the model by denying the importance of its inherent complexity. Linear causality is not in itself an illusion.

The illusion is that we believe we are able to explain the complexity around us by using linear causality alone.

Systems Thinking and Positive Peace

Systems thinking forms the basis of how we think about Positive Peace. An example would be the relationship between the free flow of information and a well-functioning government.

Governments can regulate what information is available, but information can also change governments. The two are highly correlated and mutually affect each other.

This is very different from causal thinking where the effect does not influence the cause.

Memories in Laos: Applying systems thinking

One of my best memories, and an experience that made me think about systems, occurred in Laos in the early 1990s.

At the time, Laos was a closed country for all but a few Westerners and when we visited villages there, sometimes a six-hour drive over dusty dirt tracks, hundreds of people would turn out simply to see us.

They always held a welcoming ceremony for us followed by a community lunch. We would sit cross-legged on the floor of the community hall, inevitably a traditional wooden building built on pillars 2 metres high.

It consisted of one room, with undulating floors that, like the walls, had cracks that you could see through. During the feast our hosts would give us copious amounts of highly potent, clear rice wine, chicken and rice.

The hospitality was impeccable, but I’ve learnt to be cautious about food. I have come down with stomach problems four times in Laos and Cambodia and each time it took from four to ten months to recover.

We would take the food, pretend to put it into our mouths, hide it in our hands and then put it into our pockets. It meant we couldn’t wear the same pants the next day. However, we did drink the rice wine.

At the end of the feast, groups of villagers would come up to tie a piece of string around our wrists – up to five people on each wrist at a time – while chanting a benevolent incantation.

It was truly moving. These were some of the more exhilarating experiences of my life.

Projects in Laos helped provide clean water and contraceptives.

One of the components was to encourage the use of contraception to increase the spacing between children.

The women quickly understood what contraception meant and its power. However, they reasoned that because contraceptives were so powerful, they were better used as a sacrifice to the rice deity.

So they would accept the pills and put them on the altar in their fields. They hoped that the deity would increase their rice yield in appreciation of such a significant offering.

‘The women quickly understood what contraception meant and its power. But they reasoned that because contraceptives were so powerful, they were better used as a sacrifice to the rice deity.’

The cause and effect

We looked at it as cause and effect. Birth control would improve the spacing of children, therefore fewer babies would die.

But that was not what happened in the system. The villagers lived in a world inhabited by deities that controlled their destinies. Their encoded norms suggested that powerful objects were best used to keep the gods happy, regardless of the other benefits that might be forgone.

Interventions will always be less effective without a clear understanding of the host system and the ability to work with it, or around it.

The solution may have been to give contraceptive pills while also providing something to sacrifice to the deities. Or changing the type of contraception, which is what happened eventually. This and similar experiences come back to me time and again.

Applying Systems Thinking to Societies

At the heart of a sustainable future is the realisation that we are part of a system, not independent of it. At one level, systems thinking is easy to grasp. Everyone gets the concept of a web of intersecting relationships.

However, once one digs below the surface it becomes more complex. When applying systems thinking to societies, its conclusions often stand in sharp contrast to traditional ways of dealing with problems.

Peace in the Age of Chaos

Most books about peace pursue a moral approach, but Steve Killelea breaks the mould with this highly original book that begins with the story of his journey from businessman, to philanthropist, and then to peacebuilder. The book spotlights peace as the intersection between a person and their society, and through the data driven theory of change, introduces systems thinking and the drivers of peace as the basis for long term societal change.
