THE MANUAL COUNTING OF PAPER BALLOTS
Counting paper ballots is inherently manual, but there are better and worse ways
of doing it. One common method is based on ballot reading and tally marks. One
member of a two-person team reads the ballot, declaring those legal votes apparent
from the voter’s marks. The second team member places a mark on his/her tally sheet
for the candidate receiving a vote. This method involves the possibility of a mistake
because the ballot is examined only once or a mistake because only one person is
doing the tallying. Since this method commonly involves reading through the entire
ballot, the ballot reader's eye and brain are not focused on looking for a single type of
data, and thus the reader must expend mental effort to distinguish among the contests
in which choices are made. (INFERIOR METHOD. I think this is how they did it in VT)
(BEST METHOD) At least one state (New Hampshire), in its state recounts, has been using another
process that seems to be less subject to error. This process, based on the use of ballot
sorting and piles, involves one member of a two-person team picking up the ballots and
placing them in piles corresponding to each choice in a particular race. The other team
member observes each ballot as it is placed in a pile. After the sorting process is
complete, one team member counts each pile in stacks of 25 and then the other team
member recounts each stack. This process enables at least two persons to
simultaneously examine each ballot at least once, and to keep things simple by
identifying choices in a single race at a time. If one person makes a mistake, the other
can catch it. This method is often modified so that each ballot is rechecked during the
stack-counting process. Hence, each ballot can be seen two times by each member of
the team, for a total of up to four views of each mark on a ballot in each race. The ballot
sorting and pile method, which involves as many examinations of the same ballot as
there are contests, is noticeably faster than the ballot reading and tally mark approach.
