I love this. Thank you for introducing me to "Norman Doors". I hadn't realized someone else had described this in such detail. I have been complaining about this years.

Ok this will be a tangent, but I also take this one step farther and also talk about "documentation". Just for the record, I don't think documentation is all good or all bad, but it definitely can be used incorrectly and in excess. And Norman Doors and a great way to get this point across.

When someone creates or installs a Norman Door by accident or out of ignorance and then realizes there is a problem, they often think "I know, I will document it!" and they add little placards to the door that says "Push/Pull" or some such. They see that this helps with a small subset of users and thinks "there, I fixed the problem, people just need to read the documentation and now it is their problem if they don't". But if you watch users of the door, a large portion will still use the door incorrectly because... people don't read documentation. If they don't read documentation, is it the users fault the door was designed incorrectly or was it the designers problem?

I use this as an example for my developers on thinking before documenting troublesome code or a confusing interface to first ask "can I design this so it is less confusing?" and if so, that would usually be preferable to adding documentation "to solve the problem". Well designed code (or doors) with no documentation always beats poor designs with documentation.

There's a funny example of even the "documentation" going wrong. At a local mall, there is a set of doors and they have put the word "PULL" (vertically like:

P

U

L

L

) on the window of the door, so from the wrong/opposite side, you still see the word "PULL" when you should PUSH (even if most of the letters are backward) so you still are tempted to take the wrong action when you see it. (I tried to explain the ridiculousness of it to the person I was with, but I don't think they cared.)

I've long suspected that I have a particular form of...dyslexia?, because I suffer from that Pull/Push thing, but also freeze when confronted with elevator door buttons that look like this: <>/><, and with public bathroom entrances, because in Spanish it's usually H/M (hombres/mujeres), but in English it's M/F (male/female), so the presence of the M throws me for a loop. My read on this is that if I see both options at the same time, my brain stutters for a second.

Same here! It's especially difficult when you're trying to quickly figure out the button to help someone who is about to miss the elevator.

Which reminds me of another "there, problem solved!" pet peeve of mine. I call it the Default Trap.

In many cases (Norman Doors are an example), there are two or more equally valid ways to do something. By "equally valid", I mean there is no clear standard for whether it should operate one way or the other, and if you ask 100 people which way it should work (which no one ever does), you get something approaching 50%.

So the product manager or perhaps developer simply says "make it a setting", and everyone agrees and declares the problem solved.

But the problem is, you have to choose a default. And 90% of the time, no one is going to change that default, or even discover how to. So you have to be very correct about assuming which value is the best default - and at that point, it probably doesn't matter that you make it an option.

The alternative I've seen to this is to ask the user which way they want it during the setup process. Light vs Dark mode is an example of this. The net result of this user choice is a longer, more complex, and burdensome onboarding process that is rife with decision fatigue. Once the user has chosen, if they don't like their choice, they may not know how to change it, since that initial action was outside of any standard interface.

The other issue with settings for everything is that the settings become bloated. In OS X, and to some extent iOS, I knew where all the settings were for the most part. Browsing them all to see what was available was a consumable thing, and I could largely remember where to go without much trouble. As macOS and iOS have added more settings to try and please everyone, and now redesigned the Settings apps... I've given up. I have no idea where most things are, what is in there, and have to search for everything and hope I use the right words.

There is an old video of Steve Jobs[0] talking about how every product is a series of decisions and trade offs. People pay companies to make all these decisions, and ideally, there is a company that makes decisions to similar enough sensibilities as yourself so that you can buy a product and use it without much fuss. It seems more and more that these decisions are all being pushed to the consumer, which in some ways makes a worse product. If I wanted infinite chose at the expense of complexity, I'd be running Gentoo or Arch. People choose macOS because it's supposed to be easy.
