SPEECH: I would like to begin with an important question: Where do wars start? From the UNESCO charter, we learn that war starts in the minds of people. War doesn’t start with AI or technology. War starts with the information we consume, in the information we distribute and engage with, and with the information we create. This implies an important social change that comes from the Fourth Industrial Revolution, specifically from the creation of information networks, how they operate, and how we are part of the distribution process.
In today’s networks, information is the main good that we are discussing and distributing, creating. Then, it is essential to understand the information creation process. Coming from the idea of the minds of people, it’s in our minds where the separation of us vs. them is created. It usually relies on the creation of stereotypes and highlighting the differences that create divisions; in other words, division is fueled by not knowing each other and the lack of understanding of what can make us a common group. These ideas impact us deeply. On one side, they lead us to the use of stereotypes that secure separation, and on the other side, they help us to justify the creation, consumption, and distribution of a very particular type of information. In consequence, information as a tool must be evaluated as a chain.
When we talk about misinformation or disinformation as a tool for warfare, we’re usually looking at the idea of the creation of this type of information. Thus, when we refer to disinformation campaigns, we limit its study to an operation in which information has been purposely created to produce some harm. In this scenario, we recognize the use of bots, mass distribution of content specially designed for social media and internet-based platforms.
On the side of misinformation, we refer to information that might not have been created with the purpose of causing some harm, but it ends with conversations that are misleading. One example of this happened recently in Costa Rica when one congressman visited an area affected by intense rains, and when sharing about it with the media, he sent a picture of him in the affected place but from a previous visit. We know that he visited the area, but when he sent an image that was not from that very specific moment, he was misleading the media and the population in general. In conclusion, the main difference between misinformation and disinformation is the purpose and the goals for which they are created.
Continuing with the idea of the information chain, once it is created, it is massively distributed, permeating the information ecosystem, in both digital and non-digital networks. The digital distribution usually starts in social media, which is one of the biggest dissemination channels for this type of information because it is fast, emotional, and easy to relate to the situations people are facing. Then we also have media taking over, in some cases, traditional media using breakout news, without an exhaustive checking process.
Some of the problems we see in the distribution process are the existence of echo chambers. These are networks created around our interests and that impede us from receiving information that is posted outside those chambers. So, thinking of the idea that war starts in the mind of people, if we’re only receiving information that is confirming our stereotypes and biases, then it is extremely easy to use information as a tool for warfare, because it is endorsing the preexisting believe of us vs. them. Then, the question is, how do we break this cycle? What do we do? The answer is simple: analyze the information. Some of the questions we can ask ourselves are: What is this information bringing to me as a person? How am I part of this echo chamber? Am I contributing to the distribution of misinformation or disinformation?
Disinformation campaigns rely on the use of emotions to ensure a connection with the audience. Thus, if it is relying on us vs. them, outrage and stereotypes, fear, anxiety, and conflict, then it is very likely that we are receiving disinformation.
To move away from the temptation to share that content, we need to consider our responsibility and find a path to disrupt the cycle, and it is precisely on this point that we go back to our minds.
If we are conscious of who we are in the network society, how this information is getting to us, then it’s easy to take effective actions to break the cycle by doing something different. To counter the effects of these campaigns, it is worth identifying the main beneficiary of the information, the context, or the group for which disinformation is relevant, and considering the larger effects of the division that it is causing.
We must recognize that it will be specific people or groups who are creating this type of information and disinformation campaigns, with clear goals and intentions. They need society to think about a specific topic, and they are disseminating information to increase division and polarization. This is why, before sharing, it is crucial to stop and say: Is it worth sharing?
These are simple questions to explore, and that I want to leave you with, because if war begins in the minds of people, so does peace. We need to be intentional in the creation of peace, and for that, awareness of the type of information we consume and share is essential. If we can fight the temptation of sharing content that promotes division and polarization, we can do our part to build the society we want.
As we say at the University for Peace, if you want peace, work for peace. This work starts with us, in the most private space – our mind – and from there it impacts our networks and our society. If you can identify how the information is affecting you and stop the distribution cycle, you’re already building peace.
As users, we’re not powerless, we can create change by bringing unity when we recognize the us vs. them dynamic, dismantling echo chambers by accessing different ideas and consuming information that challenges our believes, and stopping the cycle by impeding the limitation of these types of contents. Change doesn’t happen suddenly, but remember, if you want peace, work for it.
