Final answer:
The most common reason for writing a scientific article is to inform readers by providing factual, evidence-based information and contributing to the scientific community's knowledge.
Step-by-step explanation:
The most common reason for writing a scientific article is to inform readers. Scientists and researchers share their findings through publications to contribute to the collective knowledge of the scientific community and to document their research for peer review. When writing a scientific article, the purpose is often to report new research findings, to explain how science works or to detail a methodological approach. While there can be an element of persuasion, particularly when discussing implications or recommending applications of the research, the primary intent is to provide factual, evidence-based information.
The tone of scientific writing is typically neutral, aimed at an audience that values empirical evidence and logical reasoning. To ensure that readers will take the findings seriously, authors establish credibility by including their credentials and by citing reliable sources. Furthermore, scientific articles help readers think critically about a topic and give strength or credibility to the ideas presented through rigorous methodology and analysis.
