A lesson on the importance of using established patterns, courtesy of my frustration today with Amazon.

Iāve been lucky enough to work in the realm of design for a long time, so I get frustrated when something simple doesnāt look or work the way I expect, even if it doesnāt really matter.
Side note: Iām all for experimenting and creativity, but Iām hardpressed to see how this is good for the user in any fashion. Also, itās totally cool for you to think Iām blowing this out of proportion. I kind of am, but details matter.
For the curious (you, I hope), if you want to read a full book description, you have to click a āRead moreā control, which reveals the full summary. Hereās what it looks like:

The orientation of the little arrow (carrot, chevron, call it what you willā¦) makes zero sense. Typically, you expect an arrow to indicate the action it will take, but in this case, it is pointing the one direction that is least associated with revealing additional text below the current text. Does the left arrow mean that something will appear on the left, or the text will move that way or, what?!
It would make far more sense to have that arrow point right to open it and left to close it:
> Read moreĀ
< Read less
Or down to open it and up to close it:
ā±½ Read more
ā Read less
Or a combo pointing right to open it and up to close it (see the next section):
> Read more
ā Read less
Amazon designers knowĀ better
Look no further than a few pixels above our initial example to show the right way to mark up the exact same type of control:

Yup, exactly what weād expect.
Amazon is (in)famous for its culture of experimenting with every last detail, so I wouldnāt be surprised if this silently disappears down the road. I hope it will. But, it serves as a great reminder that not everything needs to be tested. There are a lot of established patterns that work specifically because of how humans think.
(I also wouldnāt be surprised if a Designer lost the argument about trying this in the first place.)
Arrows specifically indicate direction. They focus attention and move the eye to a specific place. This isnāt unique to the web or online productsāāāitās a pattern we encounter everywhere online and off.
The inconsistency only compounds the issue and frustration.
Amazon can do better.
Iām not even going to dig into the myriad other ways theyāre using arrows on the exact same pageā¦
