Trust, Heart, and Logic: Use Data to Power Your Mission’s Impact

by Doug Weiss | Dec 19, 2025 | Consulting, Fundraising

When you use data to demonstrate your organization’s effectiveness, you build trust and credibility. But bear in mind: While data connects with the mind, stories grab the heart. So, combine both, and you create a compelling message that engages donors, inspires your audience, and demonstrates measurable impact.

In today’s world of information overload, your audience must constantly evaluate whether your message is authentic and effective. Yes, donors want to see the impact of your mission—but they also want to feel it.

The power of Aristotle’s rhetorical triangle

Aristotle’s rhetorical triangle is a classic model for persuasive communication that emphasizes three appeals: ethos, pathos, and logos. When used together, they provide a framework to help you build stories that are both emotionally moving and logically convincing.

Ethos: build credibility and trust

Ethos appeals to the audience’s sense of credibility and authority. It answers the question, “Why should I believe you?”

Nonprofits and ministries build credibility through authenticity and transparency. Share your mission clearly and back it up with stories of real impact. Highlight the expertise of your leadership, showcase testimonials from those you serve, and celebrate partnerships that add credibility.

Pathos: connect through emotion

Pathos appeals to the emotions. This is the heartbeat of storytelling. Emotional stories create empathy, which then helps your audience understand the human side of your mission.

For instance, instead of a presentation that contains only your annual statistics, add the story of Lisa—a single mother who found hope and stability through your programs. Once the audience connects with Lisa’s story, you can add, “Last year, 250 families like Lisa’s found permanent housing through our program.”

This approach transforms a number into a story of impact.

Logos: engage logic with data

Logos appeals to reason and logic. It is where your data reinforces your story and demonstrates measurable results. Data provides structure and validation and gives your audience confidence that your organization is effective and responsible. Emotions move people to act; numbers show them their action makes a difference.

For example:

  • “Our discipleship program helped 50 students grow in their walk with God.”
  • “Since we launched our clean water initiative, 12 new wells have been built, which provide safe drinking water for over 5,000 people.”

These facts build a logical case for your organization’s impact. But remember: The goal is not to overwhelm with statistics; rather, the goal is to integrate meaningful data points that strengthen your story.

When storytelling and data come together, they create a dynamic message that builds trust (ethos), connects with hearts (pathos), and satisfies logic (logos). This balanced approach transforms ordinary communication into a story of purpose, progress, and proof.
