To assist with this task, researchers have developed a variety of methods to portray spatial uncertainty. While there has been some testing of the effectiveness of these displays, the possible effects of such representations on decision-making have not yet been thoroughly investigated. Indeed, studies from the psychological literature indicate that people do not always make the same decisions when presented with the same information, and they can also be sensitive to the effects of presentation, task, and context. This paper examines how the use of four different methods to represent positional uncertainty can affect spatial decision-making. The authors found that extremely significant differences in participants' responses were exhibited, depending on the manner in which positional uncertainty was displayed, although little difference was observed in the ability of the participants to comprehend the four display methods. In addition, strong preferences were recorded for certain representations over others.

Testing the effects of thematic uncertainty on spatial decision-making / S. Hope in Cartography and Geographic Information Science, vol 34 n° 3 (July 2007)

There is now a growing recognition that this uncertainty should be communicated to information consumers if they are to be fully informed regarding the decisions being made on the basis of the underlying data. Research to date has tended to focus on the issues of how uncertainty information can be modeled and visualized, with less consideration being given to the subject of how users might apply such information. Studies in the psychological literature clearly indicate decision-making biases when information is ambiguous, with most people displaying ambiguity aversion. Therefore, the research question we seek to answer in this paper is “Do people exhibit a similar bias towards uncertain spatial information?” This paper examines the effects of introducing thematic uncertainty to spatial information in the context of a decision task. The results indicate that many people, including those who consider themselves to be experienced in working with spatial information, do not have an intuitive understanding of how to handle uncertainty in decision-making. Furthermore, our findings reveal that the inclusion of uncertainty information in a GIS output can lead to irrational decisions being made—instead of promoting robust, more fully informed decision-making as intended.
