I remember twenty years ago teaching my parents double click, they then spend years on computer and they still cant understand it. They have 4 modes in their mental model, Left Click, Right Click, and Double Click on both Left and Right. They dont understand when to use which.

A lot of nerds / geeks/ tech people to this day still dont understand what makes the whole touch screen / iPhone UX so special. Scott Forstall said it [2] these people just dont get it. The single tap app opening may have been trivial for most of us, it was a world of difference to 95% of consumers. ( And that is why you should not put these people into consumer tech product design )

[1] Something Steve Jobs said with regards to people dont know how to use a keyboard, but I cant find the video with Google. It was during an interview with Walt Mossberg.

We spent an entire lecture on the concept of right-clicking, and several lectures on changing fonts and font sizes in Microsoft Word.

It blew my mind that this was not innately intuitive, forgetting that I grew up with all of this and it's as second nature my generation as breathing.

If something works when you do it... you just get a habit of it.
