Georgia doing “hand recount” of 2020 Presidential Election Ballots. Why is “hand recount” better than “computer rescan”?
My initial judgement is that a "computer rescan" would have less chance of being biased and less change of making mistakes than a "hand recount", and so the "hand recount" can only introduce more uncertainty and a worse quality result. Is there any reason I should think otherwise? And if the result is not qualitatively better, then what? 2 out of 3?
