According to the Merriam-Webster dictionary, Objective is defined as "expressing or dealing with perceived facts or conditions without distortion by personal feelings, prejudices, or interpretations." And the Cambridge Dictionary gives the similar definition: “based on actual facts and not influenced by personal beliefs or feelings.” It is obvious that to be objective, personal opinions about the research question or hypothesis must be eliminated in the research design, research process and reporting method. The aim of any type of research is to be objective, which means that the result can show more effective information and can be generalized to more situations. Almost all books on research method in social sciences discuss that research should be objective and focus more on how to be objective. They state that the research method can determine whether the research findings are objective or not (Fowler, 2009, etc.). In particular, research methods such as randomly selected participants, Latin square for the arrangement of experiment levels between subjects and double-blind experience, etc. they are designed to achieve the research objective. It seems that objectivity is an "automatic presupposition if the instruments are sufficiently scientific." (Cassel, 2002). However, it is difficult to find a paper that discusses the likelihood that research findings are not objective. Considering that social science research focuses more on complex human behaviors (Jackson, 2007), the study of conflict as a social science subject is, in my opinion, impossible to be objective. Since human behaviors are complex and are influenced by changes in mood or emotions, by situations around oneself and by information coming from outside, interpersonal interaction...... at the center of the card ..... .it is as much as possible in the world of human beings. quantitative research paper and find out some factors related to the conflict, such as cultural background, religion, economic situation and so on. Then it will be easier for the next search to compare the search results and get more information. Nowadays, subjective evaluation is a popular research topic, as are subjective evaluations of happiness, workload, and stress. I suppose that this kind of research approach may be suitable for studies on conflict situations, because the conflict situation is related to human emotions and behaviors, so it should be more effective to ask subjects to evaluate their subjective levels and to do statistics with values ​​based on subjective evaluation. The results can also be compared between groups and obtain a “subjective” conclusion based on the data.
