Paper – Iceberg Sensemaking: A Process Model for Critical Data Analysis and Visualization” (arXiv 2022)

Charles Berret and Tamara Munzner

Abstract
We offer a new model of the sensemaking process for data science and visual analytics. Whereas past sensemaking models have been built on theoretical foundations in cognitivism and positivism, this model adopts interpretivist foundations in order to reframe data sensemaking in humanistic terms. We identify five key principles centered on the concept of schemas: Tacit and Explicit Schemas, Schemas First and Always, Data as a Schematic Artifact, Schematic Multiplicity, and Sensemaking Over Time. Our model uses the analogy of an iceberg, where data is the visible tip of the schema underneath it. The analysis process iteratively refines both the data and its schema in tandem. We compare the roles of schemas in past sensemaking models and draw conceptual distinctions based on a historical review of schemas in different philosophical traditions. We validate the descriptive, predictive, and explanatory power of our model through four analysis scenarios: uncovering data injustice, investigating official data, teaching data wrangling, and producing data mashups.

Journalism – “Newsrooms are making leaking easier and more secure than ever” (CJR 2017)

As a break from dissertation writing, I accepted an invitation from the editors of the Columbia Journalism Review to write an article revisiting last year’s Tow Center report on the use of SecureDrop in newsrooms. Here in the early months of the Trump presidency, all indications point to an incredible surge in the use of secure whistleblowing tools among Washington insiders hoping to contact journalists anonymously. A handful of my sources not only confirmed that this is the case, but also offered some sense of how they’ve coordinated this growing stream of information. Find the article here.

Interview – Talking SecureDrop on the “It’s All Journalism” Podcast

Posting this a bit late, but I was invited to speak on the podcast “It’s All Journalism” back in June. They were curious about my research on SecureDrop and I think we covered the subject pretty well in just under thirty minutes.
