Given a ballot box and a line up of people without asking any questions could Sherlock Holmes figure out who voted what?
@email@example.com assuming that this exists in a real-world location and not in an amorphous void-world like most logic problems? absolutely
@firstname.lastname@example.org he would know the local political climate and the ballot options; he would be able to deduce the occupational history and class status of each person in the line, as well as a number of personality characteristics; he would be able to identify in detail how they feel about being at the ballot location and how they feel being around the other people in the ballot line
combining those pieces of information, he could form a very accurate picture of each person's ballot
@email@example.com however, i don't think he'd bother doing this unless he was bored, standing in line to drop off his own ballot, lmao
