Quote by Daniel Kahneman
““System 2 and the electrical circuits in your home both have limited capacity, but they respond differently to threatened overload. A breaker trips when the demand for current is excessive, causing all devices on that circuit to lose power at once. In contrast, the response to mental overload is selective and precise: System 2 protects the most important activity, so it receives the attention it needs; “spare capacity” is allocated second by second to other tasks. In our version of the gorilla experiment, we instructed the participants to assign priority to the digit task.””

System 2 manages mental overload by allocating attention selectively, unlike electrical breakers that cut power to all devices.
In simple terms: Mental focus works like a circuit breaker, protecting key tasks while sharing spare capacity.
