Sloman Neptun Quotes

[That] the driving force of the evolution of human intelligence was the coordination of multiple cognitive systems to pursue complex, shared goals [is called] the social brain hypothesis. It attributes the increase in intelligence to the increasing size and complexity of hominid social groups. Living in a group confers advantages, as we have seen with hunting, but it also demands certain cognitive abilities. It requires the ability to communicate in sophisticated ways, to understand and incorporate the perspectives of others, and to share common goals. The social brain hypothesis posits that the cognitive demands and adaptive advantages associated with living in a group created a snowball effect: As groups got larger and developed more complex joint behaviors, individuals developed new capabilities to support those behaviors. These new capabilities in turn allowed groups to get even larger and allowed group behavior to become even more complex. ~ Steven Sloman

Individual humans know embarrassingly little about the world, and as history progressed, they came to know less and less. A hunter-gatherer in the Stone Age knew how to make her own clothes, how to start a fire, how to hunt rabbits and how to escape lions. We think we know far more today, but as individuals, we actually know far less. We rely on the expertise of others for almost all our needs. In one humbling experiment, people were asked to evaluate how well they understood the workings of an ordinary zip. Most people confidently replied that they understood them very well – after all, they use zips all the time. They were then asked to describe in as much detail as possible all the steps involved in the zip's operation. Most had no idea.2 This is what Steven Sloman and Philip Fernbach have termed 'the knowledge illusion'. We think we know a lot, even though individually we know very little, because we treat knowledge in the minds of others as if it were our own. ~ Yuval Noah Harari
