Any sources for this? I tend to share this sentiment, but have never really read too deeply into it.

To further this, I think it is important to acknowledge too that these design decisions are not made exclusively because they "look nice." There is value in "sameness" when you are competing with other products/brands/sites that have already established a certain style, convention or pattern. After all, we learn and orient ourselves by subconsciously comparing new experiences with ones we've already had. So when you experience similar patterns in a new interface, it drastically decreases the cognitive load in learning how to use it. To your point though, there is a fine line in how effectively you can push simplicity, and there are many subtle visual variables beyond the reductionist square button that could help to improve legibility of elements as distinct components that are largely ignored in current trends.
The article?
> We also found arrow icons highlight ‘action’ links for users wanting to find help. They're noticeable but, unlike buttons, users actually read the link.
I think it just depends, some things we think are UI affordances aren't, I'm not sure it's just minimalism vs not. Just that you gotta test.

Again the fashion for extreme flatness, with square icons and buttons that disappear into the background are shown to be counter productive and user hostile.
They might "look nice" to some lead designer, but they don't work as well.
Now, if only Google, Microsoft et al were to wake up to this.
The icons the NHS have used seem to nod to hospital signage too - the arrow, the proportions etc. Probably intentional, working from the same start point, but not mentioned here.
