There's a speed limit to human thought — and it's ridiculously low

How fast do humans think? According to a new study, it's slower than you might expect.

The peripheral nervous system — the network of nerves that deliver 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 10 bits per second, researchers report in the study.
