Iceberg Sensemaking =================== Type: Research Organization: UBC and Linköping University Dates: 2022-25 Topics: Critical visualization, Sensemaking, Data practice, Epistemic humility Summary ------- A process model, written with Tamara Munzner, for the below-the-waterline schemas and judgment that shape any data analysis, kept separate from the newsroom papers Charles co-authored as an academic advisor. Project Notes ------------- Iceberg Sensemaking, written with Tamara Munzner, starts from a simple problem: data is only the visible part of an analysis. Beneath it are schemas about what exists, what matters, and how observations should be organized. Those schemas may remain tacit, even while they determine what can be collected and what a result can mean. The model describes analysis as an iterative process of adding, checking, and refining both data and schemas. It treats data as a schematic artifact rather than a neutral representation, and it allows multiple interpretations to remain in play instead of forcing them into a single account. Four scenarios test the model against practical problems: data that was never collected, data wrangling, inconvenient observations, and the apparent objectivity of sensors. The paper offers analysts a vocabulary for examining their own interpretive work. Its aim is not to make judgment disappear, but to make judgment available for scrutiny. Related newsroom studies on data preparation and multi-table wrangling (Dirty Data in the Newsroom, Table Scraps, OpenRoundup) were led by Stephen Kasica as doctoral research. Charles appears on those papers as co-author and academic advisor, not as lead author. They are catalogued under Writing with that credit, not as primary exhibits of this project.
