Cool paper! learned a lot about shared beliefs. But I was asking myself "why is 50k traders using similar trading patterns an example of collective intelligence"? I expected an example of a collective accomplishing a group goal as opposed to optimizing individual ability to accomplish goals. Noted in first paragraph: "we still lack a coherent formal perspective on what human collective intelligence actually is". But, why not reference the closest definition or propose your own rigorous definition of collective intelligence to ground assumptions in the paper? For instance, in 2007 Legg and Hutter presented a paper, "A Definition of Machine Intelligence" (http://arxiv.org/pdf/0712.3329v1.pdf http://arxiv.org/pdf/0712.3329v1.pdf) which inventoried existing definitions of machine intelligence and suggested their own definition. Seems like these definitional papers would be the starting point for presenting research on any kind of intelligence. Do you see meaningful work in this direction regarding defining collection intelligence?

Thanks! The collective intelligence task in this case is for the community on the site to identify who are the best traders to be mimicking. It's not an explicit group goal, but we are treating it as an implicit one. I wouldn't say we are trying to define collective intelligence per se. e.g., when you offer a model of a dynamical physical process (maybe a ball arching through the air), you can hardly say that your model provides a definition of that physical system. But you can say that the physical model describes the movement of the ball. In the same way, I'd instead say we are simply trying to grabble with how to think about collective intelligence. We are offering a model and a class of models that we expect to display collectively intelligent behavior, and we thereby hypothesize that these models might also explain how collective intelligence in human groups might arise.
