“Second to his investing talents, Warren Buffet is known for having a deep-rooted respect for clear communication within companies. His own shareholder letters are so well written that they are often considered the gold standard for the medium.
When introducing the SEC’s official Plain English Handbook, Buffet chose to offer up his “unoriginal but useful tip” to act as if you are communicating to a single person.
Buffet usually writes with one of his sisters in mind, noting that while highly intelligent, she has little experience with investing. If he sees a passage that will confuse her, he knows he hasn’t written it properly.
Good advice to all kinds of writing, including academic writing.
