Spent time with #Tableau calculated fields today. Created Product Value Category field & ran into problem - some products categorized as BOTH categories. Took a min to realize: transaction-level data means same product, different prices. Note to self: check data structure before building categories.

Getting more confident with calculated fields in Tableau. Understanding how to create categories and conditions without modifying source data. Game-changer for analysis flexibility. Small wins add up. #datafam What Tableau feature clicked for you once you actually used it?" #dataviz

Spent 2 hours yesterday working on Tableau fundamentals. Still very much a beginner learning how to work with calculated fields, but I'm committed to building real fluency with data tools. #datafam For anyone else learning #dataviz: what's a tricky technical concept you're wrestling with right now?

One of the loudest bells tolling for social science right now is that the decade of abundant data on humans is coming to a close. Whether you work on digital trace or surveys, LLM pollution is a serious problem, even while the wide roll out of LLMs creates an urgent need for social science.
A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸
How about we reconsider the idea that sciencey science involves collecting own data.

AI-generated ‘participants’ can lead social science experiments astray, study finds
Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

Re-upping this again. I assisted the amazing team at @onthemedia.bsky.social developing the breaking news consumers handbook, and its recommendations still hold true to this day.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Σ Waterfall charts are perfect for showing both individual contributions & cumulative impact. Each bar shows how much each subcategory adds to total- you can instantly see which categories drive the biggest changes.

≡ Arrays and matrices are basically the same (unlike in math/programming) because #Tableau treats everything as "rows × columns." Arrays store lists of values, matrices represent data structure - but both are just rectangular grids. I was probably just overthinking this 👀 #dataviz #LearningInPublic

≠ Until recently, I sometimes confused dimensions vs attributes in #Tableau (because they're both categorical) - classic case of surface similarity bias. But now I know dimensions structure your viz (create groups), while attributes just add context (annotate). #dataviz #datapsych #LearningInPublic

🤯 #Tableau hierarchy order matters! I thought they were just groupings but they're drill-down paths (duh). My "database table" mindset made me miss the tree structure hiding in plain sight 🧠

But instead we scientists are a bunch of cowards, afraid to rock the boat, indoctrinated to rationalize the status quo.

I really beg datavis researchers to start engaging with this.
The role of the chart here is to provide a cover of objectivity.
It’s reifying the entire fucking opinion section into a 2d space to lens it some Cartesian legitimacy or something equally dark. So, so gross.

We can quibble about the placement of each item but the original sin here is the very existence of this graph. Why on earth would a news organization rank social issues like they're weapons in an RPG?
Of course the NYT sees the "DEI" stuff positively & is neutral on anti-trans discrimination

Part of my dissertation on history of psych examined the mental hygiene movement. Trump's obsession with IQ and 'the blood' are clearly based on essentialist eugenics (marginalized after WWII, but never disappeared). We are seeing re-normalization of bigoted, factless 100+ year old false narrative.
