Evidence Usage and Guidelines


Remember: Each Debater is responsible for the material he or she reads in a round. Thus, the quality of the evidence in the team file is very important. Do not turn anything in to the team file unless you are very sure about the quality of the source. Be sure that all evidence you turn in is true to the intent of the source that you have quoted.

Additional Guidelines:
  • Full source citation on each bit of testimony -- author, author's qualifications, publication, date, and page. Qualifications are important and should indicate the author's credibility on the issues discussed by the cited testimony.
  • Type evidence (make sure the print is dark enough) on standard size white paper so it will copy well for distribution.
  • Do not edit, alter, or take evidence out of context.
  • Put a claim (thesis argument) at the top of each quote so we know how to file and use the material. Claims must be a clear, short statement of the argument derived from the evidence. General, descriptive categories are not acceptable.
  • Put your initials at the end of each quote so we know who to contact with questions.
  • If -- and it is better that this never happens -- there is any editing, use standard marks to show what is altered ( ... for parts left out and [ ] for items inserted ). This is ONLY done when needed to make the testimony clear. On any edited evidence the meaning of the card must not be changed as a result of the edit. You must provide a photocopy of the original for each piece of edited testimony you turn in.
  • No page breaks in the middle of a card. This makes copying too difficult.
  • Make sure that the evidence is no wider than 6 inches across so that it will fit on 4 x 6 note cards.
  • The bulk of evidence submitted should favor books, scholarly publications or field specific journals. Journalistic sources (newspapers, magazines) should be used sparingly and, if used, should consist predominantly of "experts" rather than "staff writers."
