"States should conduct post - election risk - limiting audits . A risk - limiting audit involves hand counting a certain number of ballots to determine whether the reported election outcome was correct. Risk - limiting audits used advanced statistical methods to enable states t o determine that the original vote count was accurate with a high degree of confidence. These audits are useful in detecting any incorrect election outcomes, whether they are caused by a cyberattack or something more mundane like a programming error. Mor eover, conducting these audits as a matter of course increases public confidence in the election system."
