A reasonable person will want to observe a few short rules when reconstructing or evaluating history. Adapted from Wendie E. Schneider’s distillation of the 2000 ruling in Irving v. Penguin Books and Lipstadt.

1. Know the Basics of Evidence
a. Primary Evidence is created by a participant in the event under investigation
i. Contemporary evidence is created at the time of the event
ii. Late evidence (usually recollection) is created after the event
b. Secondary Evidence, contemporary or late, is created by those not present at the event and often includes interpolation or speculation
c. Provenance
i. If the story or artifact changed hands, was there opportunity for unintentional error to have crept in?
ii. Was any source likely to have altered the story or artifact?
d. Plausibility
i. Is the story or artifact anachronistic?
ii. Is the story or artifact contradicted by science?
2. Evaluate the Evidence before Publishing a Conclusion
a. Treat all sources with appropriate reservations
b. Do not dismiss counter-evidence without scholarly consideration
c. Be even-handed in treatment of evidence
d. Identify speculation when suggesting conclusions
e. Correctly transcribe or translate documents. Omissions or elisions should be used to clarify evidence, not alter it
f. Weigh the authenticity of all accounts
g. Consider the motives of historical actors
3. Avoid Fraud, the deliberate misrepresentation or manipulation of historical evidence
a. Do not knowingly present forgery as genuine
b. Do not suggest implausible reasons for dismissing genuine evidence or reasonable conjecture
c. Do not attribute distorted conclusions to sources
d. Do not manipulate statistics to alter conclusions
e. Do not deliberately mis-translate texts
