It is extremely easy to convince yourself that the current system works. Numerous people volunteer to work in election monitoring every year, and any person who is not sure can take a day or two off work to do so at their next election.

Plus, the system overall is dead simple, first grade math skills are enough to understand it: we just count the votes in every precinct, and sum up the votes later up. No hashes, no smart group theory schemes, nothing complex.

Yup. I did this in 2020 and came away pleased at how well the system was designed.

In my country there is usually a recount in some "suspicious" voting stations. The recount about never gives the same results as the original count. People are not very good at counting even if they have good intentions.

-people are bad at counting

-some people might be bad at counting on purpose

-some people might try to influence the results

This happens all the time as proven by multiple recounts. I am not talking about USA here but about EU countries but I imagine it's the same in USA. You just hope those swings are small enough to not influence the end results. I am sure this is usually true but sometimes it's close and then the odds are at least some of those elections went the wrong way.
