I agree with ciphergoth that we would probably have an easier time discussing political issues than some other communities, and I agree with HalFinney that it's probably not a very good use of our time anyway. Let's say that everyone on LessWrong agrees on a solution to some political problem. So what? We already have lots of good ideas no one will listen to. It doesn't take a long-time reader of Overcoming Bias to realize marijuana criminalization isn't working so well, but so far the efforts of groups with far more resources than ourselves have been mostly in vain.

If someone came up with a new idea for pulling ropes sideways, that might be useful. For example, Robin's idea of futarchy is interesting, although so large-scale that it would be very hard to implement. If someone came up with a suggestion that brilliant, but for a smaller problem, it might do some good. But I always interpreted our posting policies to permit that sort of thing anyway.

But I think the best thing we could possibly do would be to raise the sanity waterline - a rising tide lifts all boats. That means coming up with compact, attractive summaries of our key findings and spreading them as far as possible. More on this later, possibly.
