Thinking

**Author:** John Brockman

**Estimated Reading Time:** 42 minutes

**What You'll Learn:**

How leading scientists understand the mind, why your brain is more like a political arena than a computer, what forecasting tournaments reveal about expert predictions, why simple heuristics often beat complex analysis, how your brain mispredicts your own future feelings, and what rare neurological conditions teach us about human nature.

**Who This Book Is For:**

Anyone who wants to understand how the mind actually works, not how we imagine it works. This book is for readers curious about the frontiers of cognitive science, behavioral economics, neuroscience, and social psychology. It is for people who make decisions under uncertainty, which is to say, everyone.

Every era has a dominant metaphor for the mind. In the age of hydraulics, the mind was a system of pressures and flows. In the age of the telegraph, it was a network of signals. In the age of the computer, it became an information processor, a machine that takes inputs, runs algorithms, and produces outputs. But what if the mind is not a machine at all? What if the brain is better understood as a society, a collection of competing agents with their own interests, forming alliances, breaking them, and sometimes working at cross-purposes? What if the stability we experience as consciousness is not the default state of the system but a hard-won achievement, a temporary truce among warring factions? These are the questions that animate the conversations in John Brockman's Thinking. Brockman, through his Edge Foundation, has spent decades bringing together the world's most innovative scientists and asking them the questions that matter. This book collects the insights that emerged from those conversations, and the result is a portrait of the mind that is far stranger and more interesting than the one most of us carry around. The problem is that most people operate with an outdated model of their own minds. They believe they are rational actors who carefully weigh evidence and make optimal decisions. They believe their memories are reliable recordings of past events. They believe their predictions about their own future feelings are accurate. They believe their moral judgments are the product of careful reasoning. The research presented in this book suggests otherwise. Consider the humble neuron. For decades, neuroscientists treated neurons as simple switches, dutiful components in a vast computational machine. But what happens when you think of neurons as agents, entities with their own agendas that must be kept in line and properly rewarded? What happens when you recognize that neurons can form coalitions, compete for influence, and even rebel against the system that contains them? The answer is that the brain starts to look less like a bureaucracy…
