Replication package for: Why Good Experience Can End Joint Activity

Replication package for Zhang, W., "Why Good Experience Can End Joint Activity" (preprint arXiv:2611.02292). It contains the Python code, the anonymized aggregate model inputs, and the simulation and analysis outputs behind the paper's figures, tables and numerical statements. The raw survey files are publicly available on OSF (Vaccarino, Raposo and Muise, 2025; Vowels et al., 2018; Columbus et al., 2021) and are not included here; data_processing/sources.json lists where to download each of the four files. With the released aggregate inputs, the analysis can be reproduced from Step 2 without them. README.md gives the setup and the commands for each replication step, and maps the output files to the paper's figures and tables. A full run takes about an hour.
