From the chapter:

In this chapter, we will review the cognitive and psychological research related to collective intelligence. We will begin by exploring how cognitive biases can affect collective behavior, both in individuals and in groups. Next, we will discuss the issue of expertise, and discuss how more knowledgeable individuals may behave differently, and how they can be identified. We will also review some recent research on consensus-based models and meta-cognitive models such as the Bayesian truth serum that identify knowledgeable individuals in the absence of any ground truth. We will then look at how information sharing between individuals affects the collective performance, and review a number of studies that manipulate how that information is shared. Finally, we will look at collective intelligence within a single mind.
