Sources & limits.

Numbered citations in each article identify the relevant sources. These records have different purposes and evidentiary weight.

  1. Wand et al., The Butterfly Did It (American Political Science Review, 2001) ↗

    Original peer-reviewed statistical research. Estimated mistaken choices are not individually identified votes or an official revised tally.

  2. Florida Supreme Court, Fladell v. Palm Beach County Canvassing Board (December 1, 2000) ↗

    Primary judicial opinion. Its narrow legal test for voiding an election does not measure usability or prove that no voters were confused.

  3. NIST Election Glossary: overvote, undervote and residual vote ↗

    Technical definitions, not a retrospective finding about an individual Florida ballot; the linked glossary is labeled draft version 1.0.

  4. GAO-02-122: Statistical Analysis of Factors That Affected Uncounted Votes (October 15, 2001) ↗

    Independent federal audit research on national county-level patterns. Correlation and unexplained variation do not establish a coordinated fraud scheme.

  5. Roy Saltman: Improving the Voting Process, NIST colloquium (September 21, 2007) ↗

    Historical technical lecture by an independent consultant and former NBS researcher, hosted by NIST. His interpretations are attributed; hosting is not a court finding.
