Visual Villainy

How to undermine humanity with evil dataviz.

You’ve heard “how charts lie.” Maybe you’ve fibbed with statistics. Perhaps you’ve even dabbled with truncated y-axes. But this talk will encourage you to be even more ambitious with your evil data deeds.

Instead of just misleading audiences, why not unravel the social fabric of society? Or sabotage an election? Or spread mis­information?

To do this, we’ll explore an evil toolkit of design techniques that are scientifically proven to promote the three P’s of evil dataviz: Plagues, Prejudice, and Polarization.


Workshop Overview

Let’s say you’ve been hired by evil alligators to create evil dataviz. Your design goal is to unleash havoc and general mayhem. How might we use dataviz to sow division, spread pandemics, and convince your fellow citizens that climate-change-induced sea level rise is in their best interest?

Your goals may not be so nefarious, but your charts might be. Trusted institutions like the EPA, CDC, and Census Department don’t intend for their data to cause mayhem, but this is often the effect.

This humorous keynote is adapted from Eli Holder and Gabrielle Merite's Outlier 2024 keynote address. It promotes positively influential dataviz through a bit of silly reverse psychology.

In this workshop, we’ll learn ways to make better non-evil dataviz by exploring some of the many odd ways data visualization can be accidentally evil. We’ll review recent dataviz research projects related to the social impact of data visualization, data advocacy and data journalism.

By highlighting ways to make evil charts, we hope to give social-impact oriented data communicators a more intuitive sense of the ways that data advocacy can backfire and some alternative approaches for creating more positively disruptive charts.


"Your talk was easily my favorite amongst all the great talks this past week! It was a super clever way to address bias in data viz."

"Amazing presentation today! I don't think I've ever intentionally done an evil data visualization but your talk certainly made me rethink some of my assumptions."

"[The talk] is pushing me to practice more visualizations showing variability and look out for deceptive visuals."

"Visual Villainy... was brilliant! I was really looking forward to attending this keynote live (virtually) that despite having 4 hours of sleep (thanks to a teething toddler), I opened up my computer at 7:30 am to make sure I don't miss it live. They cleverly show us how specific dataviz and design techniques can mislead to promote prejudice, polarization and plagues. The tips are SOO good that I'm scared their keynote will be watched by the wrong group"
Data Communication Coach

Learning Objectives

After this workshop, attendees will learn:

Motivation. Understanding the latest research on the downstream consequences of social misbeliefs, and how they’re promoted by popular, conventional wisdom in data visualization design.

Awareness. Using the ABSURD framework to identify six critical sources of information backfire and how they manifest in public facing dataviz.

  1. Always Be Neutral
  2. Blame People Not Systems
  3. Stir Dissent With Stereotypes
  4. Undermine Social Norms
  5. Repeat, Repeat, Repeat
  6. Doomsday

New visualization techniques. Learn alternative visualization approaches for social impact, by tracing chart examples from “good” to “evil.”
