The speed limit of human thought is ridiculously low

How fast do humans think? It’s slower than you might expect. The peripheral nervous system, the network of nerves that delivers information between the brain and the body, takes in environmental information at over a billion bits per second, a speed comparable to a lightning-fast internet connection. But people think and process that information at just ten bits per second. This vast gulf hints at major unexplored questions in neuroscience and human cognition. “That number is ridiculously small ...
