So some people were shown, "Today is election day," the simpler one, and some people were shown the one with that tiny tweak with those little thumbnails of your friends who clicked on "I voted." This simple tweak. OK? So the pictures were the only change, and that post shown just once turned out an additional 340,000 voters in that election, according to this research as confirmed by the voter rolls. A fluke? No. Because in 2012, they repeated the same experiment.
Solo esa pequeña modificación. Así que las fotos fueron el único cambio, y esa publicación que fue mostrada solo una vez añadió 340 000 votantes en esa elección, según este estudio confirmado por los padrones electorales. ¿Suerte? No. Porque en 2012, repitieron el experimento.
