Critical thinking refers to deliberately scrutinizing and evaluating theories, concepts, or ideas using reasoned reflection and in-depth analysis. The act of thinking critically involves moving beyond simply understanding information, but extend your reasoning by questioning the source of information, its production, and its presentation in order to expose potential bias or researcher subjectivity [i.e., evidence of being influenced by personal opinions and feelings rather than by external determinants].
Applying critical thinking to investigating a research problem involves actively challenging basic assumptions and questioning the choices and potential motives underpinning how a study was designed and executed and how the author arrived at particular conclusions or recommended courses of action. Applying critical thinking to writing involves effectively synthesizing information and generating compelling arguments.

Applying Critical Thinking to Research and Writing
Professors like to use the term critical thinking; in fact, the idea of being a critical thinker permeates much of higher education writ large. In the classroom, the idea of thinking critically is often mentioned by professors when students ask how they should approach writing a research paper [other approaches your professor might mention include interdisciplinarity, compare and contrast, gendered perspective, multicultural, global, etc.]. However, critical thinking is more than just an approach to research and writing. It is an acquired skill associated with becoming a complex learner capable of discerning important relationships among the elements of, as well as integrating multiple ways of understanding applied to, the research problem. Critical thinking is the lens through which you holistically interrogate a topic.
Given this, critical thinking encompasses a variety of inter-related connotations applied to writing a college-level research paper:
As noted, critical thinking permeates the entire research and writing process. However, it applies in particular to the literature review and discussion sections of your paper. These two sections of a research paper most clearly reflect the external/internal duality of thinking critically.
In reviewing the literature, it is important to reflect upon specific aspects of prior research, such as, 1) determining if the research design effectively establishes cause and effect relationships or provides insight into explaining why certain phenomena do or do not occur; 2) assessing whether the method of gathering data or information supports the objectives of your study; and, 3) evaluating if the assumptions used to arrive at a specific conclusion are evidence-based and relevant to addressing the topic. Critically thinking applies to these elements of reviewing prior research by assessing how each source might perpetuate inequalities or hide the voices of others, thereby, limiting its applicability for understanding the scope of the problem and its impact throughout society.
Critical thinking applies to the discussion section of your paper because this is where you contemplate the findings of your study and explain its significance in relation to addressing the research problem. Discussion involves more than just summarizing findings and describing outcomes. It includes deliberately reflecting upon the importance of the findings and providing a reasoned explanation why your paper helps fill a gap in the literature or expand knowledge and understanding in ways that inform practice. Critical thinking also uses reflection to examine your own beliefs concerning the significance of the results in ways that avoid using biased judgment and decision making.
Using Questions to Enable Critical Thinking
At its most fundamental level, critical thinking is thinking about thinking in ways that improve the effectiveness of your ability to reason, analyze, synthesize, evaluate, and report information and, as a result, it advances deeper explorations of the topic*. From a practical standpoint, critical thinking is an act of introspective self-examination that involves formulating open-ended questions that inspire higher levels of reasoning about a research problem. The purpose of asking questions during the research process is to apply a framework of inquiry that challenges conventional assumptions, scrutinizes the evidence presented, determines how effectively arguments have been supported by that evidence, discerns patterns or trends in the findings, and helps imagine alternative outcomes if new or different factors were introduced.
Below are examples of questions about prior research that can stimulate critical thinking:
NOTE: Being a critical thinker doesn't just happen. Casting a critical eye on how effectively others have studied a research problem requires developing self-confidence in your own abilities to actively engage with information, to consistently ask how and why questions concerning the research, and to deliberately analyze arguments and recommendations set forth by the author. Examining critically your own beliefs and feeling about your writing involves a willingness to be comfortable questioning yourself in a way that promotes a strong sense of self-awareness and introspection. Together, these outward and inward looking habits can help improve your critical thinking skills and inform how to effectively research and write a college-level research paper.
