Advance apologies for coming across strong, but for an article advocating clarity, it is utterly devoid of an examples of how to actually achieve it. If your title starts with "How to..." you should SHOW, not TELL, and the article was a whole lot of telling. And the one example that was accidentally there - the image at the top - did not clarify if it was a good one or not (see discussion here, for example).

Others have found issue with the grammar and sentence structure of the article, I found it totally opaque.

Show me an example of a mental model (or the absence of one). Pull an excerpt from the Times or the economist and contrast it with another publication that is not clear. Wouldnt this help us "understand, know and" eventually "do"?

And given that the advice is to think about your audiences and communicate with purpose, please do ask yourself: What is the purpose of this article? If it's to tell us to strive for clarity, please show us how, don't just tell us to do so.
