Discovering communication strategies to drive social change

In the information age, where narratives compete for attention, the skill of persuasion becomes an essential tool for organizations focused on social development. However, the challenge extends beyond merely transmitting messages. Ethically exercised persuasive communication seeks to establish an emotional bond that motivates and generates commitment. It always respects individual freedom and recognizes that each person has their own way of understanding the world and making informed decisions. Often, arguments contrary to their viewpoints are ignored or adapted to pre-existing cognitive patterns, making the change in opinion and behavior a complex and delicate process.

Today is Giving Tuesday, and I’d like to use this day as an ideal stage to explore how persuasion techniques can be a catalyst for social change. This analysis questions traditional methods like the ‘Matlock Method‘, where presenting compelling data is believed to be enough to convince. This approach often fails because it assumes that society, if not understanding or sharing our worldview, simply lacks information. This perspective treats society as a passive jury that only needs to be ‘informed’ to make the ‘right’ decision, without considering the broader context. It fails to recognize that people are constantly bombarded with information and face time constraints in their daily lives, affecting their ability and willingness to process new messages.

Think for a moment about how you started to care about the cause you defend or the policies you wish to promote. Was it through an informative brochure, direct contact with the problem, or perhaps a positive personal experience? It’s emotions that engage us. If the strategy you’re using for your project is not the one that would have motivated you, why expect it to work for others?

In this context, persuasion for sustainable development is a complex process that involves more than mere argumentation. It is intrinsically linked to understanding people’s attitudes, beliefs, and values. This process seeks not only to inform but also to transform, starting with an emotional and experiential connection that can lead to active commitment to a cause.

The relevance of persuasion in NGOs

For non-governmental organizations and social justice initiatives, navigating the vast sea of data and information requires more than just presenting convincing facts. Persuasion here manifests in the ability to create messages that not only reach the public but also mobilize them through a process of personal and emotional transformation. An example is the World Wildlife Fund (WWF) initiative for endangered species conservation. WWF uses impactful images and emotive narratives, but their success is also due to how they guide their audience through Rogers’ theory stages: from awareness of the crisis to the confirmation of their commitment to conservation.

WWF’s strategy illustrates how understanding these stages can help NGOs design more effective communications. Initially, they focus on awareness, using data and evidence to make the problem visible. Then, through emotional narratives and interpersonal communication, they move their audience to the persuasion stage, where positive attitudes and beliefs towards the cause are generated. Decision and implementation come when individuals take concrete actions, like donating or participating in conservation campaigns. Finally, confirmation occurs when WWF recognizes and values its members’ commitment, not just with a thank-you but by keeping them informed about the impact of their actions and how they contribute to broader achievements. This continuous positive feedback creates a lasting support cycle, where members feel an integral part of the mission and motivated to continue participating.

Effective influence methods: Applying Cialdini's 6 principles of persuasion

Robert Cialdini, a prominent psychologist and author of “Influence: The Psychology of Persuasion“, one of my go-to books, has been a key figure in the study of persuasion and its profound effect on decision-making. His six principles of persuasion are vital for understanding how the psychology of persuasion is essential to deciphering our daily decision-making and what preferences have been identified by scientists for communicators or strategists to effectively reach their audience and generate a significant and lasting impact.

  1. Reciprocity – Khan Foundation: The Khan Foundation exemplifies the principle of reciprocity by offering free, high-quality education. This generosity prompts users to support and promote the foundation, creating a cycle of giving and receiving that strengthens the community and the organization’s mission.
  2. Commitment and consistency – Greenpeace: Greenpeace employs the principle of commitment and consistency by encouraging people to take small actions, such as signing a petition, that gradually lead to more significant commitments. This technique ensures that followers remain true to their initial values, strengthening their long-term relationship with the organization.
  3. Social proof – Save the Children: Save the Children applies the principle of social proof by sharing testimonials from children and families benefited by their programs. These personal and moving stories not only demonstrate the real impact of their work but also motivate others to join and support the cause.
  4. Authority – World Health Organization (WHO): WHO uses the principle of authority by backing its public health campaigns with statements from recognized medical experts. This strategy increases the credibility and trust in their messages, encouraging the audience to take action based on expert advice.
  5. Liking – UNICEF: UNICEF employs the principle of liking by using charismatic spokespersons and emotional campaigns to connect with their audience. The presence of celebrities and the creation of messages that resonate emotionally with the public increase the effectiveness of their campaigns.
  6. Scarcity – Natural Disaster Response: Natural disaster response campaigns illustrate the principle of scarcity, emphasizing the immediate need for help and the urgency to act. This perception of limited time and urgency motivates people to contribute quickly.

Case study: and persuasion in action, co-founded by renowned actor and activist Matt Damon along with former football player Gary White, has become an exemplary model of how to use effective persuasion techniques in communication for development. Their innovative and sustainable approach to the global water crisis has made a significant impact, demonstrating the power of strategic and emotionally resonant communication.

Applying Aristotle's classic persuasion concepts in a real campaign: DonorsChoose

Aristotle’s persuasion principles, far from being mere techniques, are fundamental pillars in the psychology of human motivation with deep roots in the history of thought. To illustrate how these principles are applied in a modern and cohesive context, let’s take the example of the Giving Tuesday 2022 campaign by DonorsChoose, a platform that allows people to donate directly to school projects.

  • Pathos (Emotion): DonorsChoose shared moving stories of benefited classrooms and students. These emotive narratives created a deep connection with the audience, motivating action through empathy and emotional commitment.
  • Ethos (Credibility): The platform established its credibility by showing the tangible impact of donations on educational projects. Testimonials from teachers and data on project success reinforced trust in their mission and the effectiveness of their methods.
  • Logos (Logic): DonorsChoose also used data and statistics to underline the importance of education in the development of students and communities. They presented logical and well-founded arguments to convince donors of the critical need for their work.
  • Kairos (Opportunity): Capitalizing on the opportune moment of Giving Tuesday, the platform intensified the urgency of their message. This strategic timing with a day dedicated to generosity maximized public attention and support.

This campaign is a notable example of how effective integration of Pathos, Ethos, Logos, and Kairos can generate significant impact. On this occasion, they managed to raise a substantial amount of funds, demonstrating the efficacy of applying these millennia-old principles in modern communication strategies.


Ethically and creatively applied persuasion is a transformative force in the world of NGOs and social justice initiatives. This analysis reveals that beyond mere strategies, persuasion techniques are bridges that connect hearts and minds with vital causes, driving attention and action.

In an era of abundant but often disoriented information, the ability to communicate with purpose and passion becomes essential. As communicators, we have the challenge and opportunity to use our skills to positively influence, narrate meaningful stories, and motivate collective action toward a more equitable and empathetic world.
