With so much information at our fingertips, it's important to be able to critically evaluate information to distinguish trustworthy and relevant information from unreliable and irrelevant data. For example, when searching online for information to support an essay, being able to tell if a website is a suitable, high quality source is vital. The ability to evaluate information is not just a useful skill at college and university, but also in life in general. There is a growing problem of online misinformation over the last decade, so being able to spot when the information you're presented with may be false or heavily biased will ensure you stay well informed.

One method of evaluating an information source is to apply the CRAAP test. This stands for Currency, Relevance, Authority, Accuracy and Purpose. These criteria are useful measures of a source's credibility, so use these prompts to kickstart your evaluation.
How recent is the information?
The importance of currency depends on your topic. You may need to think carefully about when your sources were published. An older source isn't necessarily a bad source, but more recently published books and articles tend to provide more up-to-date and reliable information. For example, articles published in the 90s won't help you if you're writing an essay on contemporary crime statistics, but if you were doing a comparison of crime statistics over time, you would need sources from many different decades.
Is the information relevant to your research question or assignment objectives?
The information you use should directly address your research question. It should also be the appropriate level for you needs - not too simplistic and not too advanced. Always consider if your sources offers unique information that you haven't seen in other sources.
Who is the author or publisher?
Is the author an expert in this field? Check their credentials and affiliations.
In the case of websites, check the domain to see if its commercial, education or governmental.
A source's authority is one of the most significant indicators of its reliability.
How reliable, truthful or correct is the information?
Look at the evidence provided and see if it's supported by the data or research. Has the information been reviewed or vetted? For example, journal articles published in peer-reviewed journals hold more credibility. Books recommended by your tutors or library information advisers are more reliable/
Also think about the language of the information source. Is it clearly relying on supported evidence and citations? Or is it make emotional driven arguments? This could be an indication of bias, or a source with an agenda.
For what reason does the information exist?
Has the information been produced to inform, to sell a product, to persuade readers to a certain opinion, or to entertain?
In traditional research or reading, an individual might deeply engage with a single source, reading it from top to bottom and trying to glean its validity from the content alone. Lateral reading, on the other hand, is about moving outside the initial source and conducting quick searches about the information or the organisation presenting it. Instead of diving deep into a single source, you're skimming across multiple sources to validate the first.
If in doubt and you're not sure about the quality of a source, you can always ask your Library Information Adviser for help.
