Tiene la matemática el poder para descifrar cómo funciona un sistema específico de voto electrónico?
En 2004 en Venezuela se realizó un referéndum del cual dependía la permanencia de Hugo Chávez Frías en la presidencia de la República. El resultado oficial le dio el triunfo y gracias a ello pudo mantenerse en el poder. Este fue el debut de las máquinas de votación de Smartmatic. La falta de transparencia que marcó aquel evento dejó en muchos venezolanos la sensación de fraude. Varios grupos de académicos produjeron escritos que muestran evidencias, basadas en matemática estadística contra la veracidad los resultados que habían dado las máquinas. Algunos de ellos fueron publicados por importantes revistas científicas como International Statistical Review y Statistical Science. Smartmatic comenzó una vertiginosa expansión que la llevó a ser líder mundial en la automatización del voto. Sólo siete meses después de aquel referéndum compró Sequoia Voting System, compañía que años más tarde pasaría a ser propiedad de Dominion Voting System. Por todo esto, descifrar cómo funcionan las máquinas de votación que se estrenaron en la Venezuela gobernada por Chávez, es un tema relevante y global. A lo largo de este libro, su autor, Guillermo Salas, físico y coautor del artículo Analysis of the 2004 Venezuela Referendum: The Official Results Versus the Petition Signatures publicado por Statistical Science, muestra una serie de hechos que le permiten al lector responder por sí mismo si la matemática tiene o no el poder para descifrar el funcionamiento de este sistema de votación. Lo hace usando un lenguaje sencillo, intuitivo y ameno, que no requiere del lector conocimientos especializados.Pay with
