Before using information from a source, you should always critically evaluate it. What does this mean?
It means approaching new information or an unfamiliar source with some skepticism. You know better than to accept everything you're told at face value, so don't treat research any different. How do you know it can be trusted? How do you know if it is an appropriate source to use for your purposes?
While your brain is already evaluating new information everyday, taking some time think about specific questions to ask yourself and how to answer those questions is helpful.
Before using any information you should critically evaluate the source. Put it through the CRAAP Test:
