AI-assisted social media posting increases the volume of content people produce. However, that content is perceived as lower quality than purely human-generated posts. A dangerous spiral that may flood social media with low-quality content. Results from a controlled study:

This is a poor argument against LLM simulations. It suggests that LLM-based behavioral models should capture nuances that no model ever has (do agent-based models go to the toilet?). Ofc, ABM is meant to be interpretable, but social science also needs predictive power (where LLM simulations excel)
