Text reads: About synthetic panels Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels. Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey. Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away.
Text reads: Question-writing best practices To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices: Ask forward-looking and attitudinal questions. Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, “How likely are you to try…?” Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, “When did you last visit…?”
Text reads: Discussion The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002) of the variance in behaviour to be explained by intention and PBC.
Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?
Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"
Good luck drawing reliable conclusions from the answers that Qualtrics' AI model provides to your survey questions... bsky.app/profile/joac...
At today’s lab reading group @carolin-holtermann.bsky.social presented ‘Fairness through Difference Awareness: Measuring Desired Group Discrimination in LLMs’ by @angelinawang.bsky.social et al. (2025).
Lots to think about how we evaluate fairness in language models!
#NLProc #fairness #LLMs
Also see more nuanced takes worth reading from @seanjwestwood.bsky.social (x.com/seanjwestwoo...) and @joshmccrain.bsky.social (bsky.app/profile/josh...) and @phe-lim.bsky.social (bsky.app/profile/phe-...)
The path forward: Survey panels and crowdsourcing platforms must invest in better panel curation and periodic quality verification.
Good to see that @joinprolific.bsky.social is already on it: bsky.app/profile/phe-...
✅ LLM instruction tuning works: tell a model to answer as a human, it will
❌ Silicon sampling still doesn't work: AI responses are plausible but don't accurately represent a real human population
❌ Bot detection fails: it's hard to design tasks that are easy for humans but difficult for LLMs
Now that the hype has cooled off, here's my take on AI-generated survey answers:
This is a real problem, but the paper's core insights aren't exactly news!
A thread with the most important summary... 🧵

Another exhausting day in the lab… conducting very rigorous panettone analysis. Pandoro was evaluated too, because we believe in fair experimental design.
For our weekly reading group, @joachimbaumann.bsky.social presented the upcoming PNAS article "The potential existential threat of large language models to online survey research" by @
@seanjwestwood.bsky.social.
Google AI overviews now reach over 2B users worldwide. But how reliable are they on high stakes topics - for instance, pregnancy and baby care?
We have a new paper - led by Desheng Hu, now accepted at @icwsm.bsky.social - exploring that and finding many issues

Next Wednesday, we are very excited to have
@joachimbaumann.bsky.social, who will present co-authored work on "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation". Paper and information on how to join ⬇️
Can AI simulate human behavior? 🧠
The promise is revolutionary for science & policy. But there’s a huge "IF": Do these simulations actually reflect reality?
To find out, we introduce SimBench: The first large-scale benchmark for group-level social simulation. (1/9)
Cool paper by @eddieyang.bsky.social, confirming our LLM hacking findings (arxiv.org/abs/2509.08825):
✓ LLMs are brittle data annotators
✓ Downstream conclusions flip frequently: LLM hacking risk is real!
✓ Bias correction methods can help but have trade-offs
✓ Use human expert whenever possible
Looks interesting! We have been facing this exact issue - finding big inconsistencies across different LLMs rating the same text.
About last week’s internal hackathon 😏
Last week, we -- the (Amazing) Social Computing Group, held an internal hackathon to work on our informally called “Cultural Imperialism” project.
If you feel uneasy using LLMs for data annotation, you are right (if not, you should). It offers new chances for research that is difficult with traditional #NLP/#textasdata methods, but the risk of false conclusions is high!
Experiment + *evidence-based* mitigation strategies in this preprint 👇
The 94% LLM hacking success rate is achieved by annotating data with several model-prompt configs, then choosing the one that yields the desired result (70% if considering SOTA models only).
The 31-50% risk reflects well-intentioned researchers who just run one reasonable config w/o cherry-picking.
Thank you, Florian :) We use two methods, CDI and DSL. Both debias LLM annotations and reduce false positive conclusions to about 3-13%, on average, but at the cost of a much higher Type II risk (up to 92%). The human-only conclusions have a pretty low Type I risk as well, at a lower Type II risk.
Great question! Performance and LLM hacking risk are negatively correlated. So easy tasks do have lower risk. But even tasks with 96% F1 score showed up to 16% risk of wrong conclusions. Validation is important because high annotation performance doesn't guarantee correct conclusions.
We used 199 different prompts total: some from prior work, others based on human annotation guidelines, and some simple semantic paraphrases
Even when LLMs correctly identify significant effects, estimated effect sizes still deviate from true values by 40-77% (see Type M risk, Table 3 and Figure 3)
Thank you to the amazing @paul-rottger.bsky.social @aurman21.bsky.social @albertwendsjo.bsky.social @florplaza.bsky.social @jbgruber.bsky.social @dirkhovy.bsky.social for this fun collaboration!!
Why this matters: LLM hacking affects any field using AI for data analysis–not just computational social science!
Please check out our preprint, we'd be happy to receive your feedback!
#LLMHacking #SocialScience #ResearchIntegrity #Reproducibility #DataAnnotation #NLP #OpenScience #Statistics
The good news: we found solutions that help mitigate this:
✅ Larger, more capable models are safer (but no guarantee).
✅ Few human annotations beat many AI annotations.
✅ Testing several models and configurations on held-out data helps.
✅ Pre-registering AI choices can prevent cherry-picking.
- Researchers using SOTA models like GPT-4o face a 31-50% chance of false conclusions for plausible hypotheses.
- Risk peaks near significance thresholds (p=0.05), where 70% of "discoveries" may be false.
- Regression correction methods often don't work as they trade off Type I vs. Type II errors.
We tested 18 LLMs on 37 social science annotation tasks (13M labels, 1.4M regressions). By trying different models and prompts, you can make 94% of null results appear statistically significant–or flip findings completely 68% of the time.
Importantly this also concerns well-intentioned researchers!
