## About

This research is part of the [SYNTH research project (#546323839)](https://gepris.dfg.de/gepris/projekt/546323839?language=en), which is conducted as part of the [META-REP Priority Program](https://gepris.dfg.de/gepris/projekt/441890184) aiming to improve the replicability, reproducibility, and generalizability of empirical research in the behavioral sciences. SYNTH contributes to these goals by integrating large language models into current research workflows to reduce burdens on scientists while improving transparency and replicability.
