Passing out flyers seems superior to leaving books around. It more closely resembles awareness raising methods used by most charities, and I think a flyer can be a more effective sales pitch (with a pointer to a website where you can read more) than a book cover. Additionally it should be cheaper per person reached by far, and could give Less Wrong users practice with rejection therapy.
I have a friend who passed out flyers with some success for his life extension charity, and claims to have a contact in the Berkeley area who will pass out flyers for cheap. He tried to get Michael Anissimov to design an SI flyer for this guy to pass out, but Anissimov didn't end up going for it. Get in touch with me if you want.
If anyone feels that they know the issues (extremely) well enough to co-write a succinct, informative, and punchy SI flyer with me, I encourage them to get in contact: michael@intelligence.org. My other assignments prevent me from following through on this alone, I'm afraid. I do appreciate being encouraged to do this, I just feel that it's too much responsibility to take on alone. Such a flyer would need to be of a high quality to give a favorable impression.
Series: How to Purchase AI Risk Reduction
Here's another way we might purchase existential risk reduction: the production of short primers on crucial topics.
Resources like The Sequences and NickBostrom.com have been incredibly effective at gathering and creating a community engaged in x-risk reduction (either through direct action or, perhaps more importantly, through donations), but most people who could make a difference probably won't take the time to read The Sequences or academic papers.
One solution? Short primers on crucial topics.
Facing the Singularity is one example. I'm waiting for some work from remote researchers before I write the last chapter, but once it's complete we'll produce a PDF version and a Kindle version. Already, several people (including Jaan Tallinn) use it as a standard introduction they send to AI risk newbies.
These could even be printed and left lying around wherever we think is most important: say, at the top math, computer science, and formal philosophy departments in the English-speaking world.
The major difficulty in executing such a project would be in finding good writers with the relevant knowledge. Eliezer, Yvain, and myself might qualify, but right now the three of us are otherwise occupied. The time investment of the primary author(s) could be minimized by outsourcing as much of the work as possible to SI's team of remote researchers, writers, and editors.
