Change initiatives

New studies find that easily understandable information tend to spread from the centre of the network and grow outwards. However, looking at social change, it often originates in the periphery and not the core of the network. It tends to emerge in the periphery and grow around the social network only reaching the central people at the end.

This radically changes our classic notion of influence. Consequently, we need to look at what kind of information we want to spread and, most importantly, start looking for important places in the fishing nets to start spreading social change rather than looking for important people like influencers to spread the change in fireworks.

Spreading information is not enough to change people’s behaviour

From new studies on the source of social influence, we see that viral metaphors are useful to describe the way that simple ideas or information, i.e. headline news of a volcanic eruption or news of an organisational scandal, spread in networks.

But there is a big problem with this virus metaphor: to create actual change, you need to do more than spread simple information; you must change people’s behaviours. And those are much harder to influence.

"Dozens of algorithms that are currently used by enterprises seeking to spread new ideas are based on the fallacy that everything spreads virally (…) But this study shows that the ability for information to pass through a social network depends on what type of information it is.” – Damon Centola, Elihu Katz Professor of Communication, Sociology and Engineering

If you want to spread bits of information that are easily digestible, it makes sense to use influencers to spread the information like a virus through the organisation. However, innovative ideas and behaviours do not spread virally because simple exposure is not enough to “infect” you.

If you want to transmit new ways of thinking that may be difficult to understand or challenge an existing set of beliefs, you need to use another approach. When humans consider adopting a new belief or behaviour, we are guided by our own social networks like team members, close colleagues, family members, and not by “influencers”. Therefore, you must seek out hidden locations in the periphery of a network and plant the seed there in order for new beliefs or behaviour to take root and start to grow.

Change happens when people can no longer coordinate

The next bit of “magic” happens when the new idea or complex behaviour has spread from the periphery of a network to other fishing nets in the whole network.

Time and time again, social network scientists have found that once approximately 25% of people in the entire network have adopted a new behaviour, the network reaches what is commonly called “the tipping point”, and the behaviour “spreads” to larger parts of the network.

But why 25%?

The hypothesis is that once 25% of people in the network have adopted a new behaviour, the rest of the people find it difficult to coordinate social behaviour without adopting the new behaviour, for instance using a new leadership model, a new meeting structure, having a 4-day work week etc.

Metaphors matter and your brain runs on metaphors

When you read the word “metaphor” you may think about literary genres like poetry or song lyrics. But research about how the human mind works has shown that your mind runs on metaphors.

A conceptual metaphor, or cognitive metaphor, refers to the understanding of one idea, or conceptual domain, in terms of another. Like when I try to create the metaphor MIND AS A MACHINE in the rubric above by writing that the mind “runs on metaphors”, much like a machine “runs on fuel”. When the mind is conceptualised as an assembly of “mechanical” parts that uses metaphors as “fuel” to make it run, it lets us understand one idea (the human mind) in terms of another idea (a machine).

(If you’re interested in further examples of how the use of metaphors can influence organisational decision making, Gareth Morgan describes eight organisational metaphors in Images of Organization.)

Thinking about change metaphorically as a virus, you will use your knowledge about viruses, how they spread etc. to understand the domain of behavioural change. However, as you have just learnt that’s simply not how complex behavioural change actually happens.

The next step is how

We hope that you have now learnt who to target if you want to change actual behaviour and that the use of metaphors can (mis)guide decision-making. The next step is to learn how you change behaviours.

Reach out if you want to investigate how you can use behavioural design to design change initiatives that are easy and motivating for the people in the fishing nets to use. And if you want to get up to speed on the latest research within social networks, we can highly recommend the new book Change – How to Make Big Things Happen by Damon Centola, a highly accessible book filled with amazing social network research.
