The best ways to ensure that your information is accurate is to:
1. Verify the information -- if you find information from a source or website whose quality is in doubt, go to a reputable source you're familiar with or to a database to find information that supports or refutes the the less certain source.
2. Triangulate the information -- if you come across facts or opinions that are controversial or in dispute, look for three or more sources that corroborate the statement or idea.
