Podcast: Crypto-Gram 15 Dec 2006: random errors and systemic errors

from the Dec 15, 2006 Crypto-Gram Newsletter
by Bruce Schneier

There are two basic types of voting errors: random errors and systemic errors. Random errors are just that, random - equally likely to happen to anyone. In a close race, random errors won't change the result because votes intended for candidate A that mistakenly go to candidate B happen at the same rate as votes intended for B that mistakenly go to A.

Historically, recounts in close elections rarely change the result. The recount will find the few percent of the errors in each direction, and they'll cancel each other out.
