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

They say: once there’s a paper 📝, it’s real…
🎉 #MEDem in #EPS @ecpr.bsky.social

The paper outlines how MEDem will strengthen #OpenScience by making data #FAIR in #DemocracyResearch – and how scholars across Europe are joining forces to build a truly open #ResearchInfrastructure ⚙️

Screenshot of the article “Open science in democracy research: the research infrastructure ‘Monitoring Electoral Democracy’ (MEDem)” published in European Political Science. The header shows the journal name, DOI link, and the label “DEBATE.” Below, the title is followed by the author list: Hajo Boomgaarden, Alexia Katsanidou, Sylvia Kritzinger, Georg Lutz, Johanna Willmann, and Jakob-Moritz Eberl. The abstract explains the aims of MEDem as a European research infrastructure to make democracy research data FAIR (findable, accessible, interoperable, reusable). Keywords listed include open science, FAIR data, ESFRI roadmap, research infrastructure, democracy research, data harmonization, data linking, and data set search.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

Wenn man TV-Interviews zur NRW-Wahl sieht, fällt auf: Der AfD-Begriff „Altparteien“ ist inzwischen im alltäglichen Sprachgebrauch angekommen.
Das ist, was Politikwissenschaftler*innen mit Normalisierung meinen (zu der wir uns die Finger blutig schreiben seit Jahr & Tag 🙄).

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**.

Paper: arxiv.org/pdf/2509.08825

$We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation". We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks. For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations. Then, we collect 13 million LLM annotations across plausible LLM configurations. These annotations feed into 1.4 million regressions testing the hypotheses. For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions. Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors. Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models. Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.$
