Being critical in science is important.
Critically appraising information you read becomes intuitive, but like any skill set, this takes practice. As scientists, we have to make sure we consider all of the variables of the information find. There is a lot of pseudoscience and bad science out there, but there is also a lot of good science that just changes over time as we learn more
What is RADAR?
The RADAR Framework can help you remember what kinds of questions you should be asking about an information source as you evaluate it for quality and usefulness in your research.
Relevance: the importance of the information for your needs
|
Authority: the source of your information
|
Date: the timeliness of the information
|
Accuracy: the reliability, truthfulness, and correctness of the content
|
Purpose: the reason the information exists
|
What is the difference between primary, secondary, and tertiary sources?
Primary | Secondary | Tertiary |
---|---|---|
Primary sources are first-hand accounts or individual representations. They are created by those who have directly witnessed what they are describing. |
Secondary sources interpret and/or analyze primary sources, as they offer different perspectives, analyses and conclusions on a given topic. | Tertiary sources are a compilation or digest of primary and secondary materials. Generally, they are agreed upon fact. |

When you search for information online, think about the type of information you are finding online, is it scholarly or not scholarly, and how does it help you. If it's for an assignment you want to make sure it's scholarly.
Popular Information
Non-scholarly information is written at a more general level, and may be written by experts or non-experts. Non-scholarly information can help you understand a topic, but does not have the same level of authority, depth or academic rigour as scholarly material. Wikipedia is an example of non-scholarly information. While the information may be helpful you often don't know who wrote it, what their expertise is, and you cannot always trust the sources attached.
Non-Scholarly Information generally:
Academic Information:
Academic information is written by an expert in the field, and often is aimed at the level for people who are also experts in that field. While you are learning it is important to remember that you need to build a trusted foundation of knowledge. Generally this information is available in journals, textbooks, and technical documents and goes through a formal peer review process.
Scholarly information will generally include the following:
