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.

Is MAGA a community or is it a cult? 🤷

The biological transhumanism and digital eugenics promoted by some of the most powerful people in Silicon Valley amounts to pro-extinctionism, @xriskology.bsky.social‬ writes. www.techpolicy.press/digital-euge...

When Trump demands foreign countries pay tariffs, they're laughing at him 🤡 No country can force another to pay its taxes 🙄 If China imposed taxes on Americans - they'd simply ignore them. US importers pay tariffs, American consumers end up footing the bill #EconomicsExplained #TrumpTariffs 🫡

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. Easy in #Tableau with calculated field (sales difference) #dataviz #LearningInPublic

≡ 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 🧠
