CHARACTERISTICS OF SCHOLARLY SOURCES
In general, you can feel very confident about the quality and accuracy of information that you find in scholarly sources. However, scholarly sources can be challenging to use because the vocabulary and concepts are technical and specialized.
CHARACTERISTICS OF POPULAR SOURCES
It is not as easy to judge the quality and accuracy of information you find in popular sources (compared to scholarly sources). Your best bet is to stick with reputable, mainstream publications. Watch out for information that has been hyped or sensationalized.
