My point was that not everybody tries different things. We’d never gotten a complaint before because every other person would try to tap a different part of the button (it was a fairly large button that took up 90% of the width of the screen). I just picked a example that was top of mind, but I’ve seen this in a lot of different contexts involving technology. I’ve had to help people with resistive touchscreen after watching them jab at the same place over and over.

The UI should have the sole purpose of enabling a user to accurately select a candidate, but they aren’t actually made that way. The county in question even provides sticks to help make selections more accurately, so it’s apparently been an issue with their machines for years.
