To answer your question, despite David Gerard's advice:
I would not lie to donors about the likely impact of their donations, the evidence concerning SIAI's ability or inability to pull off projects, how we compare to other organizations aimed at existential risk reduction, etc. (I don't have all the answers, but I aim for accuracy and revise my beliefs and my statements as evidence comes in; I've actively tried to gather info on whether we or FHI reduce risk more per dollar, and I often recommend to donors that they do their own legwork with that charity comparison to improve knowledge and incentives). If a maniacal donor with a gun came searching for a Jew I had hidden in my house, or if I somehow had a "how to destroy the world" recipe and someone asked me how to use it, I suppose lying would be more tempting.
While I cannot speak for others, I suspect that Michael Vassar, Eliezer, Jasen, and others feel similarly, especially about the "not lying to one's cooperative partners" point.
Ideally, I'd like to save the world. One way to do that involves contributing academic research, which raises the question of what's the most effective way of doing that.
The traditional wisdom says if you want to do research, you should get a job in a university. But for the most part the system seems to be set up so that you first spend a long time working for someone else and research their ideas, after which you can lead your own group, but then most of your time will be spent on applying for grants and other administrative trivia rather than actually researching the interesting stuff. Also, in Finland at least, all professors need to also spend time doing teaching, so that's another time sink.
I suspect I would have more time to actually dedicate on research, and I could get doing it quicker, if I took a part-time job and did the research in my spare time. E.g. the recommended rates for a freelance journalist in Finland would allow me to spend a week each month doing work and three weeks doing research, of course assuming that I can pull off the freelance journalism part.
What (dis)advantages does this have compared to the traditional model?

EDIT: Note that while I certainly do appreciate comments specific to my situation, I posted this over at LW and not Discussion because I was hoping the discussion would also be useful for others who might be considering an academic path. So feel free to also provide commentary that's US-specific, say.
