!TIL 'Historian's Fallacy' - I got there through a maze of twisty little passages: 1) David Collier-Brown: "had [the British] known how to use metadata at that time, they would have identified Paul Revere as one of the organizers in Boston, well before his famous ride" http://broadcast.oreilly.com/2013/10/what-in-the-world-is-the-nsa-d.html 2) "Using Metadata to Find Paul Revere: “Social Networke Analysis,” a small encroachment on freedom, identifies terrorists in the Colonies." http://www.slate.com/articles/health_and_science/science/2013/06/prism_metadata_analysis_paul_revere_identified_by_his_connections_to_other.single.html 3) David Hackett Fischer, who coined the term "Historian's Fallacy" https://en.wikipedia.org/wiki/David_Hackett_Fischer 4) and finally https://en.wikipedia.org/wiki/Historian%27s_fallacy
