@davidaugust “completely wrong” has a double meaning here:
1- it is incorrect (see my other toots in this thread)
2- it is a damaging syllogistic thinking
I have seen designers applying this rule by refusing to have text, feedback, labels, onboarding, etc. because of the daunting fear of being told by other designers that the presence of copy was the proof of their design being a failure (which I also witnessed btw). It is nothing more than a toxic catchy sentence.
@davidaugust Another thing: “explaining the interface” has been interpreted by a lot of designers as “I don’t have to justify my choices and my work” which contributed to the designer rock star phenomenon.
The impact of this poster few years ago (when minimalism was trendy) has been extremely detrimental for the profession (behind the scene: very little designers grew in their roles with a manager being a designer too so those kind of posters were too often guiding principles)
