American voting relies heavily on technology. Voting machines and ballot counters have sped up the formerly tedious process of counting votes. Yet long-standing research shows that these technologies are susceptible to errors and manipulation that could elect the wrong person. In the 2016 presidential election, those concerns made their way into public consciousness, worrying both sides of the political fence. The uncertainty led to a set of last-minute, expensive state recounts—most of which were incomplete or blocked by courts. But we could ensure that all elections are fair and accurate with one simple low-tech fix: risk-limiting audits. Risk-limiting audits are specific to elections, but they are very similar to the audits that are routinely required of corporate America. Under them, a random sample of ballots is chosen and then hand-counted. That sample, plus a little applied math, can tell us whether the machines picked the right winner.Full Article: How Applied Mathematics Could Help Democracy - The Atlantic.
