What Is Critical Thinking? | Definition & Examples
Critical thinking is the ability to effectively analyze information and form a judgment.
To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources.
Critical thinking skills help you to:
- Identify credible sources
- Evaluate and respond to arguments
- Assess alternative viewpoints
- Test hypotheses against relevant criteria
Why is critical thinking important?
Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.
Critical thinking is important in all disciplines and throughout all stages of the research process. The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.
In an academic context, critical thinking can help you to determine whether a source:
- Is free from research bias
- Provides evidence to support its findings
- Considers alternative viewpoints
Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.
Critical thinking examples
Critical thinking can help you to identify reliable sources of information that you can cite in your research paper. It can also guide your own research methods and inform your own arguments.
Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.
Academic examples
However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.
You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them.
In this instance, you have failed to engage with the source critically and have displayed confirmation bias in accepting its conclusions based on a belief you already held.
Nonacademic examples
However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.
You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source.
In this case, you failed to look critically at the claims of the article and check whether they were backed up with evidence because you were already inclined to believe them.
How to think critically
There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.
However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test, these questions focus on the currency, relevance, authority, accuracy, and purpose of a source of information.
When encountering information, ask:
- Who is the author? Are they an expert in their field?
- What do they say? Is their argument clear? Can you summarize it?
- When did they say this? Is the source current?
- Where is the information published? Is it an academic article? Is it a blog? A newspaper article?
- Why did the author publish it? What is their motivation?
- How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion? Do they address alternative arguments?
Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:
- Am I only considering evidence that supports my preconceptions?
- Is my argument expressed clearly and backed up with credible sources?
- Would I be convinced by this argument coming from someone else?
