  • 1. Strategies for Evaluating Information Tomado de Teaching and Marketing Electronic Information Programs , 2003 . Doanld A. Barclay
  • 2. The Basic Strategy for Evaluating Information
    • Question all information regardless of its source.
    • Be reasonable – no information can be absolutely perfect.
  • 3. Currency
    • Is the information up to date?
    • If it is not, does this matter for your purpose?
      • Primary-source information may be old but still valuable.
  • 4. Example Of Currency Not Being Important
    • What year did George Washington die? Any of the following sources could provide the correct (or incorrect) information:
      • A book published in 1830.
      • An article printed in 1928.
      • A Web page created yesterday.
  • 5. Example Of Currency Being Important
      • I need information on a start-up company in which I might invest.
      • I need to decide on the best therapy for my asthma.
      • I need to know how many acres of rainforest remain in the Amazon Basin.
      • I need the most recent information on federal expenditures on education.
  • 6. Currency
    • If information is online and currency is important, when was the information last updated?
    • Be aware that date information was created may be different from date it was put in a particular “container.”
  • 7. Original information : Galen’s writings on medicine. Created circa 160 to 207 AD. Container 1 : Manuscript book written in 1150. Container 2 : Printed book published in 1821. Container 3 : Web page created in 2002.
  • 8. Authority
    • Arguably the most important thing to consider when evaluating information.
    • Authority refers to who created the information and is responsible for its credibility.
  • 9. Authority
    • Personal Author
      • An individual of group of individuals acting as an author.
    • Corporate Author
      • A business, agency, organization, or other body acting as an author.
  • 10. Authority
    • Who is the author?
      • Author should be clearly identified.
    • Is the author an authority?
      • Does the author have the education, experience, or combination of the two to write authoritatively about the topic in question?
  • 11. Authority
    • Is the author affiliated with a reputable institution (university, agency, business, etc.)?
    • Authors sometimes exaggerate, lie, or hedge about their qualifications.
      • What does it mean when an author claims to be “a leading researcher” or “a noted authority”?
      • Does a Ph.D. in music qualify an author as an expert on water pollution?
  • 12. Publisher
    • The publisher is the person or group who makes public a piece of information.
    • Many types of publishers:
      • Commercial.
      • Academic.
      • Government agency.
      • Association.
  • 13. Publisher
    • As a rule, the more reputable the publisher, the more reliable the information.
    • Self-published information is notoriously unreliable.
      • Most Web pages are self-published.
  • 14. Funding
    • Follow the money.
    • Who put up the money to make the information public?
    • Is there a conflict of interest?
      • Tobacco company pays for “research” into the effects of smoking on health.
  • 15. Print Equivalent?
    • Is a piece of electronic information the exact equivalent of printed information?
      • If so, then both are equally credible.
    • Are there discrepancies—intentional or accidental—between “identical” electronic and print versions?
  • 16. Purpose
    • All information has some purpose, such as:
      • Direct sales.
      • Advertising.
      • Public relations.
      • Education.
      • Entertainment.
      • Advocating social, religious, or political agendas.
      • Authorial ego gratification.
      • Career advancement (including earning tenure).
  • 17. Purpose
    • Information may have more than one purpose.
      • Example: A Web site could be both educational and entertaining.
    • Does the purpose of the information reveal any conflicts of interest?
  • 18. Conflict of Interest?
    • Valerie’s Vitamin Villa offers many articles extolling the benefits of taking vitamins.
    • Valerie’s Vitamin Villa also sells vitamins online.
    • Because of this conflict of interest, information from articles found on Valerie’s Vitamin Villa should undergo extra scrutiny before it is accepted as credible.
  • 19. Intended Audience
    • The intended audience can tell you if the information is appropriate for your purpose.
    • Example: Sources of information on nutrition might be aimed at one of the following audiences:
      • Children.
      • General public.
      • Owners of health-food stores.
      • Scholarly researchers.
  • 20. Accuracy
    • Web standards for spelling and grammar are looser than for print.
    • However, information riddled with errors of spelling, grammar, punctuation, or fact should raise questions.
      • If source cannot correctly spell Prozac , can you trust it to provide accurate dosage information?
  • 21. Independent Confirmation
    • Does author accurately cite the specific sources used?
    • Can the same or similar information be verified by other sources?
      • Are these sources truly independent of each other?
    • If the same bad information appears in 100 sources, that does not make it good information.
  • 22. Coverage
    • In what depth does the source cover its topic?
    • Does it include extraneous information?
    • Does it exclude information that should be included?
  • 23. Final Thoughts on Evaluating Information
    • Maintain a healthy skepticism about all information.
    • Question the purpose behind every piece of information.
    • Don’t be fooled by cool. Great graphics, polished presentation, and glib language do not in themselves guarantee that the information being presented is good information.
