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.”” [Daniel Kahneman](https://sms4smile.com/quotes/author/daniel-kahneman/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. 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. Key Takeaway Prioritize important tasks and let less critical ones wait. Themes attention mental overload prioritization cognitive control Mood focused reflective Type cognitive psychological When to use this quote - working on demanding projects - studying for exams - making important decisions - handling emergencies Key Concepts dual‑process theory resource allocation Questions to Reflect On - How do you decide which task deserves your full attention? - What strategies help you protect mental bandwidth? A Different Perspective Limited mental capacity can still be overwhelmed if too many high‑priority tasks compete. ★ ★ ★ ★ ★ No ratings yet [Capacity Respond](https://sms4smile.com/quotes/about/capacity-respond-6139971/) [Mental Overload](https://sms4smile.com/quotes/about/mental-overload-1723542/) [Overload](https://sms4smile.com/quotes/about/overload/) [Overload Breaker](https://sms4smile.com/quotes/about/overload-breaker-6139970/) [Spare Capacity](https://sms4smile.com/quotes/about/spare-capacity-4866613/) ## Related quotes > [“We normally avoid mental overload by dividing our tasks into multiple easy steps, committing intermediate results to long-term memory or to paper rather than…](https://sms4smile.com/quotes/daniel-kahneman/we-normally-avoid-mental-overload-by-dividing-our-tasks-into-multiple/) [Daniel Kahneman](https://sms4smile.com/quotes/author/daniel-kahneman/) > [The market is perfectly well supplied at the moment but spare capacity is very limited.](https://sms4smile.com/quotes/claude-mandil/the-market-is-perfectly-well-supplied-at-the-moment-but-spare/) [Claude Mandil](https://sms4smile.com/quotes/author/claude-mandil/) > [There are moments when mental overload can render words impossible.](https://sms4smile.com/quotes/nicholas-sparks/there-are-moments-when-mental-overload-can-render-words-impossible/) [Nicholas Sparks](https://sms4smile.com/quotes/author/nicholas-sparks/) > [I want to prove that Holst's 'The Planets' can be as much of a sensory overload as a concert by the Grateful Dead, and…](https://sms4smile.com/quotes/charles-hazlewood/i-want-to-prove-that-holst-s-the-planets-can-be-as-much-of-a-sensory/) [Charles Hazlewood](https://sms4smile.com/quotes/author/charles-hazlewood/) > [In an age of information overload ... the last thing any of us needs is more information about God.
