> Normal people don't understand what the word deterministic is

I would argue that they implicitly do, as any user expects the same action performed on a computer or similar system to provide the same outcome.

> For another, if they give the same task to three different people they're going to get three different results

Give the same three tasks to a single user to be executed three times separately, and he will get supremely annoyed if his actions do not give him the same results.

Not even implicitly understand. A layman is perfectly capable of understanding what deterministic behavior is, and claiming otherwise is just condescension.

Then you and I work with very different people. Here it seems "reset it and try again" is considered a viable problem solving technique.
