I assume they're in the group of users these sorts of interfaces are designed for. Hunt and peck typing, will dutifully following the flow chart of interaction across multiple pages and assume they are wrong when they are made to start again when they click a wrong button, and not being annoyed when the "you are being logged out in 30 seconds. Cancel?" message pops up. Or, they are used to finding someone who's "good with computers" to assist. That alone probably hides so much garbage UX from being known to developers.
