Something recently reminded me of Paul McHenry Roberts's How to Say Nothing in 500 Words.
It was written mostly for high school children, but it has lots of solid advice and its primary focus is something crucial: making your writing more interesting to read, aside from writing style.
The sections, "AVOID THE OBVIOUS CONTENT, "TAKE THE LESS USUAL SIDE", and "GET RID OF OBVIOUS PADDING" are most likely useless or groan-worthy obvious to anyone who's at all likely to read this comment. The only section I think is particularly likely to be relevant to rationality writers is "CALL A FOOL A FOOL".
Still, it's a pretty entertaining essay, worth reading in full unless you're really that fucking busy like Luke Muehlhauser is.
The best idea in the whole essay is,
Those sentences that come to you whole, or in two or three doughy lumps, are sure to be bad sentences. They are no creation of yours but pieces of common thought floating in the community soup.
My impression is that high school writing assignments tend not to ask for as much volume as a student can reasonably produce without padding, but college writing assignments frequently ask for more.
If one professor gives assignments demanding at least ten pages, about topics that all invite at least that much legitimate content, other professors will feel the need to assign papers of similar length, lest they give the impression that their topics are less important, or their subject less demanding. Everyone learns to pad, and comes away with the impressio...
The topics of rationality and existential risk reduction need their own Richard Dawkins. Their own Darwin. Their own Voltaire.
Rhetoric moves minds.
Students and masochists aside, people read only what is exciting. So: Want to make an impact? Be exciting. You must be heard before you can turn heads in the right direction.
Thus, I've decided to try harder and actually put effort into the quality of my writing instead of just cranking stuff out quickly so I can fill in inferential gaps and get to the cutting edge of the research subjects I care about.
That's why I asked LWers for their picks of best nonfiction writing on Less Wrong.
It's also why I've been reading lots of good science writing, focusing on those who manage to be exciting while covering fairly complex subjects: Dawkins, Sagan, Gleick, Zimmer, Shermer, Ramachandran, Roach, Sacks, Hawking, Greene, Hofstadter, Penrose, Wilson, Feynman, Kaku, Gould, Bryson, Pinker, Kurzban, and others.
I've also been re-reading lots of books and articles on how to write well: Keys to Great Writing, Style: Lessons in Clarity and Grace, Elements of Style, On Writing Well, The Classic Guide to Better Writing, The Book on Writing, Telling True Stories, Writing Tools, Ideas into Words, The Chicago Guide to Communicating Science, A Field Guide for Science Writers, Six Rules for Rewriting, Writing, Briefly, and Singularity Writing Advice. (Conversations with Eliezer also helped.)
I don't know if I can become the Voltaire of rationality and existential risk reduction, but it seems worth a shot. Every improvement in writing style is beneficial even if my starry goal is never met. Also, it appears I produce better writing without really trying than most people produce with trying. (If you've ever had to grade essays by honors English seniors, you'll know what I mean.) I expect to gain more by striving where I already excel than by pushing where I have little natural talent.
(I won't try to write everything well. Sometimes I should just crank things out. To be honest, I didn't spend much time optimizing this post.)
My other hope is that a few other writers decide they would like to be the Voltaire of rationality and/or existential risk reduction. May this post be useful to them. It's a list of recommendations on writing style pulled from many sources, in no particular order.
And, just one piece of process advice. Do not apply any of these rules while drafting. Instead, write down whatever horrible shit comes out of you and do it quickly. Then revise, revise, revise.
Now: What are your favorite pieces of writing advice?
