The internet has revolutionized the way we communicate, collaborate and share information. Online groups have emerged as a powerful tool for collective problem solving, knowledge creation and decision-making. A group of individuals can often generate better solutions to complex problems than an individual working alone. This phenomenon, known as collective intelligence, has been widely observed in various online communities, such as Wikipedia, GitHub, and Stack Overflow. In recent years, researchers have started to investigate the neural mechanisms underlying collective intelligence in online groups. In this blog post, we will explore the latest findings in this field and examine the implications of these findings for the future of online collaboration.
