23.10.2025 20:39 β π 20 π 0 π¬ 2 π 0Decision theory informs us more about what to show than how to show (or how people interpret vis in practice), so I think theory building efforts need to synthesize it with theories of perception, cognition, and social/cultural dynamics.
14.08.2025 01:27 β π 4 π 1 π¬ 1 π 0My suggestion about using decision theory as a deductive framework during design studies is one path toward codifying what we know about decision context in ways that may be useful for making testable predictions about when a particular vis design is likely to be effective.

Thanks Carlos, I didn't realize Gordon was on here.
Your work on AVD was a huge inspiration for this paper. I'd be curious to hear your thoughts on the connects we draw between disclosure and AVD vulnerabilities.
Ultimately, this paper is about the epistemology of data communication. I close with reflections on how to develop a more robust logic of generalization about decision support, and how social norms demanding that research yield guidelines that transcend context are an obstacle.
13.08.2025 16:19 β π 4 π 0 π¬ 0 π 0This work demonstrates the conceptual value of decision theory in visualization research and practice, and provides a primer for unfamiliar readers. My hope is that this will increase the adoption of ideas from decision theory in the visualization community.
13.08.2025 16:19 β π 2 π 0 π¬ 1 π 0I draw on decision theory to analyze the heterogeneity in decision problems that are studied by visualization research. By comparing examples, I call attention to the dimensions on which decision problems vary and when we can(not) expect results to transfer to different settings.
13.08.2025 16:19 β π 2 π 0 π¬ 1 π 0The dominant logic of generalization in visualization research (often implicitly) holds a strong assumption that efficacy of decoding is relatively context invariant, however, much modern research problematizes this assumption. Where does this leave us?
13.08.2025 16:19 β π 2 π 0 π¬ 1 π 0In visualization research and practice, we care a lot about supporting decision-making. However, it's not always clear how findings from empirical research generalizes to various decision contexts.

It's a big milestone for both of us, and I think she's done a wonderful job! Check out the paper and the talk at #ieeevis for more. arxiv.org/abs/2508.08383
13.08.2025 14:48 β π 4 π 0 π¬ 1 π 0I'm extremely excited to share this new paper out of the Data Cognition Lab! In it @krisha-mehta.bsky.social, Gordon Kindlmann, and I reframe visualization as a mechanism for data disclosure and develop a vocabulary for how visualization design induces loss on underlying data signals.

It was truly the honor of my life to work with such incredibly passionate people focused on improving human health. Iβve never experienced a more positive culture where *everyone* cared about their job and serving others.
I wish more HCI research was this careful about measurement. If we do turn the corner, I think weβre gonna find out that a lot of our study results donβt mean what the authors originally said they meant.

06.02.2025 23:22 β π 4 π 0 π¬ 0 π 0I also use that data set, but I ask students to encode all the variables in the table, which rules out a CDF because it doesnβt show the bacteria names. Unless they add the names with annotations. That could be cool. Avoiding occlusion and crowding would be a challenge.
06.02.2025 05:40 β π 1 π 0 π¬ 1 π 0Such a disappointment. Itβs illustrative of a deep political problem on the left, a sort of allergy to disagreement or information that goes against oneβs priorities. This just isnβt a workable approach in a democracy, especially not for a βbig tentβ party.

What tech company will be the first to stand up and say that gutting the NSF is bad actually?
The economic argument seems pretty clear
Less NSF --> fewer PhD students --> fewer researchers --> smaller AI tech pipeline --> slower progress --> less competitive globally
Most of your life wonβt go as planned. Stop placing your happiness, health, and self-actualization on the horizon.
04.02.2025 17:30 β π 4 π 1 π¬ 0 π 0My take is that the βpauseβ rhetoric is bullshit. They want to defund the universities, full stop. Idk why people are in denial that this is the game plan, to eviscerate centers of power on the left starting with educational institutions and government agencies staffed by lefty technocrats.

This is what I thought you were saying, that true marginal density estimation requires different samples, but I wasnβt completely sure. Thanks!
I think Iβm guilty of misusing Monte Carlo integration in this way. Not 100% sure what to do differently, but I appreciate your explanation of the issue.
Somewhere in the U.S., thereβs a scientist staring at their NSF/NIH grant application wondering why they bother. This post is for you. Science and society both need you. Hang in there and know there is a whole community supporting you.
