Evaluation of information is an important step in achieving information literacy. Websites especially need to be critically examined. The following are some tools that can be used to evaluate information found on the Internet:
Consider the Source: Is the source recognized as credible by the nutrition industry or profession? Does it have a history of imparting information that is balanced and unbiased? Is it potentially biased due to stated or inherent political, social, or professional affiliations? Is the source externally or internally monitored to ensure the information it imparts is fair and unbiased? Is it a primary or secondary source of information?
Check Reviews of Sources: Some common sources of reviews include Book Review Index and Periodical Abstracts. Sources dedicated to vetting online information include http://www.fastcheck.org, http://www.prwatch.org, and http://www.stinkyjournalism.org.
Determine Whether the Source is a Member of or Governed by Reputable Industry Organizations
Look for a Corroborating Source: Does an equally creditable source support the information imparted by the initial source? If not, does the difference lie in the manner in which facts are stated or in the manner they are interpreted? Either way, procede with caution.
Identify the Intended Audience: Is the source imparting information to a general audience or to an audience allied with the nutrition profession? If the information is directed to a general audience, is it thoroughly presented? Does it identify professional sources?
Identify Potential Conflicts of Interest: Is the source supported by advertising? If so, is the information imparted "advertiser friendly?"
Research the Author: Does the author have a degree or other credentials pertaining to the subject of interest? If the author or his/her professional affiliation isn't identified, what makes the author a credible source?
Evaluate the Source's/Author's Sources: Does the author cite sources to support his/her statement? Do the sources have a degree or credentials pertaining to the statement? Is there any potential bias due to political, social, or professional affiliations?
Look for Peer Reviews: Assuming the information derives from a journal, determine whether it has been peer-reviewed, meaning evaluated by qualified individuals in a related field.
Check the Date: Information gathered by online search engines frequently isn't dated. If it's not, be careful, the information may be out-of-date.
