Nate’s Notes 262: Data Scientist Sebastian Wernicke | Data Doesn’t Convince People—People Do

Great insight from Sebastian. Data doesn’t convince people. People convince people. His fuel savings example captures this perfectly. A 20% improvement felt like a win to Sebastian, but like an accusation to the employee. So Sebastian repositioned it—not as a “big fix,” but as a gradual, step-by-step pilot—making it feel natural and allowing everyone to save face. And an underappreciate tool Sebastian uses to systematically think through motivations and constraints is checklist.

And what especially helps companies make the best use of data is psychological safety. Without it, the highest-paid opinion wins, and the data gets ignored. Plus data is more like an MRI than a clear cut verdict, so it’s important to get people’s perspectives because we can all look at the same data and see a different truth.

In summary, if we want to use data more, we have to understand people better.

It’s a simple idea. Please take it seriously.
