Writing Style: Citations, grammar, precise writing rather than generalizations, no personal attacks but rather than answering an argument.
Author: What are the author's credentials? (e.g., education, background, and employer. What else have they published? *Check WorldCat, Google Scholar, & Article Databases like ProQuest, PsycInfo, or Scopus)
Read: Read the information and decide for yourself. Synthesis distinguishes research from reports.
Purpose: Look for "About us." Any bias? Is it for commerce, to advocate, or to inform?
