Bottleneck is about “the Narrowness of Now”, the shockingly low information rate of human learning, our learning bottleneck. It is what we discover when we dare to apply the science of information to the psychology of perception. The book is aimed at anyone interested in the science behind our everyday human experience, and how we learn about the world around us. It reveals insights that will forever change your perspective on the world and people around you. - There is a paradox: The world we inhabit and experience through our senses appears incredibly detailed and rich in information, yet there is no scientific evidence that we are able to absorb more than a tiny trickle of fresh information from the reality that surrounds us. Bottleneck reveals the quantifiable evidence that most of the world we experience is an internal mental construct based on our history, how our mind creates a plausible narrative to make sense of what little we actually sense. This has profound implications for interactions between humans and technology. For example; it offers a scientific insight into the process of prejudice, inviting us to peer beyond our cosy moral judgements. Bottleneck also peers into the future, exploring how our learning bottleneck imposes a fundamental limit to humanity’s ability to conceive ever greater ideas.
