You might enjoy my Evidence Based Policy discussion board at www.ebpforum.org. The site is for guessing the future results of ongoing policy experiments or have an idea of a policy that could be experimented with, you don't need to register to take part in polls where you can try to predict the results of future policy experiment results or give your opinion on whether an intervention idea would work.
