The Many Tendrils of the Octopus Map
Eduardo Puerta, Shani Spivak, Michael Correll

TL;DR
This paper analyzes how 'octopus maps' as visual metaphors influence conspiratorial thinking, highlighting the role of visual style and data features in fostering such interpretations.
Contribution
It provides a historical and empirical analysis of octopus maps, revealing how visual rhetoric can promote conspiratorial reasoning even without explicit motifs.
Findings
Visual features can induce 'octopus-like' thinking without explicit imagery.
Data and style choices influence the perception of conspiratorial narratives.
The study calls for more awareness of visual rhetoric in data visualization.
Abstract
Conspiratorial thinking can connect many distinct or distant ills to a central cause. This belief has visual form in the octopus map: a map where a central force (for instance a nation, an ideology, or an ethnicity) is depicted as a literal or figurative octopus, with extending tendrils. In this paper, we explore how octopus maps function as visual arguments through an analysis of historical examples as well as a through a crowd-sourced study on how the underlying data and the use of visual metaphors contribute to specific negative or conspiratorial interpretations. We find that many features of the data or visual style can lead to "octopus-like" thinking in visualizations, even without the use of an explicit octopus motif. We conclude with a call for a deeper analysis of visual rhetoric, and an acknowledgment of the potential for the design of data visualizations to contribute to…
