At the Modern Data Stack Conference 2021, Thomas Cooley Professor of Ethical Leadership at New York University, Jonathan Haidt, discussed how emotion and storytelling can be more persuasive than data. He explained that humans are the "last mile" for data, as they often ignore contradictory information. Our irrational side is like an elephant, difficult to control, while our rational side is a small rider on that elephant. Reason acts as a press secretary, always trying to justify what we want to believe. Haidt suggested using storytelling and speaking to deeply held values to change minds more effectively. He also emphasized the importance of understanding others and being open to discussion and disagreement.
