Writing is different. Generally speaking, argumentative essays are usually written in popular language so that all readers can understand them. SCI academic papers are usually written in professional terms, and generally only professionals can read them. The argumentation method of general papers is relatively simple, and usually only ordinary logic is used for reasoning and argumentation; SCI academic papers are often demonstrated in parallel or cross by various methods, and are demonstrated by modern scientific and technological means according to experimental data and statistical data. General papers only need to conform to the principles of reasoning and argumentation of ordinary logic, while SCI academic papers only need to conform to the principles of scientific reasoning and argumentation. The logical rigor of SCI academic papers is far stronger than that of general papers.
