Yes, and this is still true today. I work for a company with a large very non-technical user base. People absolutely will not explore, click on things outside of what they have memorized, or even try basic troubleshooting steps out of fear of breaking things.
It's actually really frustrating when trying to train to certain software or concepts because you have to lay everything out very explicitly, step by step. You cannot leave anything to the imagination or just assume that because the UI is "intuitive" that they will figure it out, because they won't even try.
I've encountered some form of that attitude and behavior at nearly every job I've had.
