I heard somewhere that people who think they're good at multitasking actually work slower than people who think they are bad at multitasking.

The reason is that when you switch between tasks, there is a mental penalty each time for that context switch. People who believe they are good at multitasking switch between tasks more often and so they pay the penalty more often.

Because although most people can multitask, vanishingly few can do it effectively.
