This is where I was supposed to look at Windows' pop-up box and read "Do you really want to...", to see what and how much I am about to delete, but evidently I didn't read it. So, maybe if I hear it...
That's exactly where the weak point is. Lots of people, both with and without experience, don't take enough time to read the messages applications pop up to ask both important and not-so-important questions. And because too often the question isn't that important, the messages that are
important fade away in the blur, and people just go for the 'right' answer to get it over with now, asap. I do that all the time, when did you last read the EULA of a new piece of software you installed? Same issues there, IMHO.
So, even when adding sound to the important message, that is going to fade away into the blur, after some time.
I once tried to get a proper, thoughtful, response by generating a random letter that had to be entered before the (usually irreversible) action is proceeded, but even then users manage to do things the wrong way, even when they really meant to do something else. There is no 1 good way, but there is no better way either.
Maybe if all we did (on our computers, ofcourse
) was reversible, then this dilemma would be solved.
