People use visualizations to make large-scale decisions, such as whether to evacuate a town before a hurricane strike, and more personal decisions, such as which medical treatment to undergo. Given their widespread use and social impact, we believe it is vital to ensure that visualizations clearly and effectively communicate data. We conduct empirical evaluations and qualitative analysis to determine how visualizations both help and hinder the decision-making process. Our goal is to use cognitive science to improve the presentation of information and to train people to be more informed information consumers.
