Using artificial intelligence responsibly is critical for academic integrity. Always adhere to these three ground rules:
- Fact-Check Every Citation: AI models can occasionally hallucinate references. Always verify sources using primary databases like Google Scholar or JSTOR.
- Maintain Your Voice: Treat AI outputs as a draft framework. Infuse your analysis, original conclusions, and personal writing voice into every paragraph.
- Check University Policies: Ensure your institution permits AI-assisted editing or research support prior to submission.
