The Probability Broach is a 1979 science fiction novel by American writer L. Neil Smith.[1]

It is set in an alternate history, the so-called "Gallatin Universe", where a libertarian society has formed on the North American continent, styled the North American Confederacy (NAC). This history was created when the Declaration of Independence has the word unanimous added to the preamble, to read that governments "derive their just power from the unanimous consent of the governed".
