We present an online platform, called BeeMe, designed to test the current boundaries of Internet collective action and problem solving.BeeMe allows a scalable internet crowd of online users to collectively control the actions of a human surrogate acting in physical space.BeeMe demonstrates how intelligent goal-oriented decision-making can emerge from large crowds in quasi real-time. We analyzed data collected from a global BeeMe live performance that involved thousands of individuals, collectively solving a sci-fi Internet mystery. We study simple heuristic algorithms that read in users' chat messages and output human actionable commands representing majority preferences, and compare their performance to the behavior of a human operator solving the same task. Results show that simple heuristics can achieve near-human performance in interpreting the democratic consensus. When human and machine's output differ, the discrepancy is often due to human bias favoring non-representative views. We discuss our results in light of previous work and the contemporary debate on democratic digital systems.Humans are extreme cooperators [18,20]. The evolution of language allowed our species to coordinate actions, thoughts and intentions. Contrary to other social species -like eusocial insects and other primates -humans cooperate in large-scale societies of largely non-related individuals [4,6,8]. The increasing returns of group scale, evident for instance in warfare, big game hunting, or tax collection, has put pressure on humans to develop norms and institutions that allow increasingly larger social groups to cooperate and act together [3,21,22]. Social norms and institutionsdefined as the set of culturally acquired rules governing the behavior of individuals in specific contexts [21]-are considered solutions to the collective action problem, arising when selfish instincts must be suppressed in favor of higher group payoffs [8,13,17]. Religion and political states are thought to have provided a range of innovations-like moralizing gods, policing and representative hierarchies -that maintain fairness, punish non-cooperators and increase
