The Art of 
Data Storytelling

A fun and bold keynote on trust, perception, and decision-making in the age of AI.

Data is everywhere. Decisions still hesitate.

•  Dashboards grow, but trust shrinks.

  AI accelerates output, but not judgement.

  Insights exist, but there is not action.

It results in 67% of people not trusting their data to make decisions.

(chances are you are feeling like this, too)

 

Let me show you how to fix it.

The problem is not the data.

The problem is how we look at it.

To understand data, you need to change the way you see. Artists train their eye to find patterns and meaning. The same mindset is crucial for data communication.

To turn perception into action, people need structure.

A way to understand how data is noticed, interpreted, and acted upon. That structure is captured in the A.R.T.-model.

A

Attention

What captures attention and frames interpretation. Attention is never neutral. What you highlight shapes what people notice, and what they ignore.

R

Recognize

How people detect patterns, interpret meaning, and decide whether data feels reliable. This is where trust is built or broken.

T

Takeaway

What people remember and do once the data story lands. No takeaway means no decision, no matter how good the data is.

In this keynote, you'll learn how to:

  • Avoid common pitfalls in data visualizations and storytelling that undermine trust

  • Understand how perception shapes data interpretation

  • Guide attention and recognition in data stories

  • Adapt insights to different audiences so they lead to action

  • Navigate the impact of AI on data storytelling without losing critical thinking
