In October 23, 2005 a national referendum was carried out in Brazil about
the prohibition of firearm commerce in the country. We combined classic poll
opinion tools and electroencephalography (EEG) analysis to study vote decision
one week before the referendum. Our poll opinion allowed people to provide
us a second opinion on if and how they could change vote until Election Day.
We also asked people to estimate the influence of media propaganda upon their
vote decision. Here we show that election results were predicted by our poll
if the vote migration disclosed by the second opinion was taken into consideration.
We also found that vote decision correlated with the EEG recorded during vote
decision-making. The estimated propaganda influence also correlated with the
EEG recorded during the reading of 6 of the most frequent media advertisement
and provided information to model the Vote Decision Space associated with
the referendum campaign.
