    "subtitle": null,
    "abstract": "The blue circle on smartphone displays is an everyday visualization of uncertainty; with the circle size indicating\nuncertainty of one’s location. Like error bars on graphs, it is a discrete visualization of a graded probability function. Two\nexperiments examined the effectiveness of different visualizations of location estimates varying whether and how uncertainty\nwas visualized (uniform blue circle showing confidence interval, faded circle showing graded probability, or both). Given a\nknown location and visualizations of the estimates of two “smartphones” of that location, participants judged which smartphone\nshowed the better location estimation. Participants reported using two primary heuristics (1) choosing the blue circle that\nwas closest to the known location (distance) and (2) choosing the smaller circle (size). Visualizing graded probability with\nfaded circles biased participants towards the distance heuristic. Visualizing confidence intervals with uniform circles biased\nparticipants towards the size heuristic (and using uncertainty information) and produced more accurate judgments",
