Cognitive Load
Your brain's bandwidth, and how to manage it
Your brain has a processing bottleneck, and it's smaller than you think. Cognitive load refers to the total amount of mental effort your working memory is handling at any given moment. When the load exceeds your capacity, performance degrades fast: you make errors, miss details, or lose track of what you were doing.
Cognitive load is why following a recipe in an unfamiliar kitchen is harder than in your own. The kitchen takes load you'd otherwise spend on the recipe. The same dynamic shows up everywhere: a difficult conversation in a noisy restaurant, complex math when you're tired, learning a new language while jet-lagged. The most useful move is usually to reduce competing demands rather than try harder. Quiet the room, finish one task before starting the next, write down what you don't need to hold in your head.
