Recent studies show that artificial intelligence (AI) is being increasingly used in research writing, sparking debates among scholars about its potential impact on the authenticity of scientific work. Researchers are beginning to see generative AI as a valid tool in academic writing, but some worry that it could compromise the integrity of genuine research.

Analyses reveal that AI-generated text has become prominent in scientific writing, with words commonly associated with large language models (LLMs) such as "intricate," "pivotal," and "meticulously" being used more frequently. Data collected from different universities indicate that a small percentage of papers in certain fields are now being assisted by AI, with a notable increase in biased reviews in some cases.

Methods like language tests and statistical analysis have been used to identify phrases and words that suggest AI assistance in scientific papers. While some words like 'red' and 'after' remained consistent, there was a significant rise in the use of specific adjectives and adverbs linked to LLM-generated content after 2023.

The study also highlighted disciplinary variations in the adoption of AI language, with fields like computer science leading the way. However, concerns have been raised about ethical challenges when using AI in academic writing, especially in tasks like abstracts and other sections of research papers. Some publishers view AI-assisted writing as plagiarism and unethical, particularly when non-human agents of LLMs contribute to the content.

As AI continues to play a growing role in research, scholars are urged to prioritize transparency and honesty in their work, ensuring that readers are informed about the methods used. While AI can enhance the efficiency of research processes, maintaining research integrity remains crucial to upholding the standards of scholarly communication and ethics in academic writing.
