If quantum scientists thought the slit experiment was exciting, they should study IT user preferences and be amazed how depending on the mode of communication/observation, customers will both scrutinize every letter you write while simultaneously not reading it at all, will know every wrong pixel of your UI but not know where the button for "Thing" (labeled "Thing") is, and how anything you make is somehow the best worst average thing they've ever seen.

If you're ever user facing it's a harsh but quick lesson that you can't really count on any users to follow any real pattern. Different persons latch onto different things, with adamant proponents and opponents of everything with a huge swatch of grey shades in-between. At a certain point you just need to decide when the "grey" is no longer grey for you on a particular subject and start to optimize for the part that cares while checking why the grey part isn't as interested.

A lot of conversations with clients I have are with those in the grey territory, where they don't quite know what they want but they know they want it. Often times, they're more looking for a reference architecture and something to compare their current processes/workflows to, and this usually is pretty simple to work with. Those that are proponents of a feature N are typically vocal and picky, but the feedback tends to be pretty good and the guidance is clear on how they envision it, since there's a clear workflow on their side a lot of times that they want to optimize. Opponents of feature N typically bring out the edge cases and demand a solution, and are equally, if not more vocal than the proponents.

It's really a tricky thing, and it's never really clear which is going to be "best" for users/the dev team.
