🚨 New preprint Do LLMs have stable dispositions measurable using instruments designed for humans? Led by @jelenameyer.bsky.social, our new preprint shows that LLM responses are driven by response bias, rendering their psychological profiles method artifacts. @dgarcia.eu @arc-mpib.bsky.social

This is a good way to think about AI’s shortfall. It’s the journey that brings satisfaction more than the destination. The AI shortcut omits the struggle/friction/elation that makes the outcome worthwhile. Weirdly, it’s also why billionaires become assholes—no friction, no joy.

New paper in Science: In a platform-independent field experiment, we show that reranking content expressing antidemocratic attitudes and partisan animosity in social media feeds alters affective polarization. 🧵
Today, social media platforms hold the sole power to study the effects of feed-ranking algorithms. We developed a platform-independent method that reranks participants’ feeds in real time and used this method to conduct a preregistered 10-day field experiment with 1256 participants on X during the 2024 US presidential campaign. Our experiment used a large language model to rerank posts that expressed antidemocratic attitudes and partisan animosity (AAPA). Decreasing or increasing AAPA exposure shifted out-party partisan animosity by more than 2 points on a 100-point feeling thermometer, with no detectable differences across party lines, providing causal evidence that exposure to AAPA content alters affective polarization. This work establishes a method to study feed algorithms without requiring platform cooperation, enabling independent evaluation of ranking interventions in naturalistic settings.

Almost back from #ic2s2 (thanks Lufthansa). The most positively-surprising impression from the conference, almost a decade after the first edition, is how much the discipline has coalesced. In 2016, it was easy to distinguish a paper authored by computer scientists vs sociologists. Not so easy now!
