Error Rates of Hand-Counted Voting Systems
The error rate for hand-counted ballots is about two percent.
All voting systems have nonzero error rates. This doesn’t surprise technologists, but does surprise the general public. There’s a myth out there that elections are perfectly accurate, down to the single vote. They’re not. If the vote is within a few percentage points, they’re likely a statistical tie. (The problem, of course, is that elections must produce a single winner.)

“two percent” I find that extraordinarily hard to believe. Ask someone from retail management if 2% failure rate in the cash drawer or a 2% failure rate in invoicing or a 2% failure rate in inventory is acceptable, even amongst overworked, underpaid, unmotivated, undersupervised low level employees. Something as simple as counting Ds and Rs by wide awake, motivated people is simply not going to fail at a 2% rate “accidentally”. There must be a flaw in the experiment. Maybe the experiment was funded or controlled by someone with an axe to grind?
