here's a preprint of the unhinged paper i wrote with @lane

we stop just short of saying that the unthinking use of frequentist statistics puts your very soul at hazard

Toward a Logic of Generalization about Visualization as a Decision Aid Visualization as a discipline often grapples with generalization by reasoning about how study results on the efficacy of a tool in one context might apply to another context. This work offers an accou...

Announcing my forthcoming short paper at #ieeevis! In this solo-author work, I examine and critique the logic of generalization about decision support in visualization research. arxiv.org/abs/2508.06751

Designing for Disclosure in Data Visualizations Visualizing data often entails data transformations that can reveal and hide information, operations we dub disclosure tactics. Whether designers hide information intentionally or as an implicit conse...

This work, with Gordon Kindlmann and @kalealex.bsky.social, marks my first paper as a PhD student. I’d love to hear your thoughts! n/n

Furthermore, we unpack broader implications of reframing visualization as a mechanism for data disclosure such as in authoring tools where designers like Fred are recommended possible visualization designs based on their disclosure goals. 8/n

From this analysis, we present a taxonomy of 13 data operations, what we dub disclosure tactics. These tactics give us a shared vocabulary to think about design tradeoffs in terms of disclosure, whether it is to protect privacy, persuade viewers, or simplify complex patterns. 7/n

We analyzed 425 examples of visualization techniques to study how designers made choices about information disclosure - about what information is hidden and what information is revealed in a chart. 6/n

In our new paper, we ask: Can these decisions be made more deliberate? Can we name and describe the operations that shape what a visualization reveals, distorts, or hides? 5/n

Without clear guidance from existing tools, he’s left to experiment until something “looks right,” hoping it meets both goals. 4/n

The image is a four-panel comic illustrating a privacy dilemma in data visualization. In the first panel, a scatterplot shows individual data points, and Fred wants to hide these while still showing clusters. The second panel shows aggregation into a heatmap, which distorts clusters and can still reveal individuals. The third panel depicts adding noise, which hides clusters but requires fine tuning and introduces spurious signals. The fourth panel shows smoothed contour shapes that reveal only the clusters, which Fred finds effective and easy to produce.

For example, imagine a bio-statistician Fred who works at a university medical center. He’s tasked with revealing clusters in patient data to an industry partner, while protecting patient privacy. 3/n

Visualizing real-world data means making tradeoffs: Datasets can be messy, high-dimensional, or contain sensitive information. Designers are constantly making judgment calls about what to show and what to leave out.  2/n

I am excited to share a new paper titled “Designing for Disclosure in Data Visualizations” set to appear at IEEE VIS 2025 (link below). 1/n

Lenacapavir: The miracle drug that could end AIDS Hard Drugs · Episode

LAUNCH DAY 🚀

Today I’m launching a new podcast, Hard Drugs, with Jacob Trefethen (@jacobtref.bsky.social)

Our first episode is about lenacapavir — a new HIV drug that blocks infections with an efficacy rate of nearly 100%, and which could completely change the fight against HIV worldwide.

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(

So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

We added global temperature anomaly charts *coloured by El Nino / La Nina periods*.

Today's "cool" years are warmer than "warm" years of the past.

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork}
