We live in an uncertain world. From weather events to financial markets, every day we are confronted with uncertainty. However, even experts have difficulty reasoning with uncertainty. Visualizations allow our visual systems to identify patterns in data that would otherwise go unnoticed. Visualizations can also help us focus on relevant data when making probabilistic judgments. Unfortunately, visualizing the uncertainty in complex phenomena such as hurricane forecasts can introduce new problems, as evidenced by the confusion associated with Hurricane Dorian's path. We study state-of-the-art uncertainty visualizations, along with the cognitive processes that lead to misunderstandings of forecast data.
