What words do you hear all the time that just sends you screaming?
'Multi-tasking', as used by employers to describe one of the requirements of a job they're advertising for.
Multi-tasking, as used to describe a human activity, is BS.
"Human multi-tasking or multitasking
is the performance by an individual of appearing to handle more than one task at the same time. The term is derived from computer multitasking. An example of multitasking is listening to a radio interview while typing an email. Multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention.
Research on human multitasking
Since the 1990s, experimental psychologists have started experiments on the nature and limits of human multitasking. It has been proven multitasking is not as workable as concentrated times. In general, these studies have disclosed that people show severe interference when even very simple tasks are performed at the same time, if both tasks require selecting and producing action (e.g., Gladstones, Regan, & Lee, 1989; Pashler, 1994). Many researchers believe that action planning represents a "bottleneck", which the human brain can only perform one task at a time."
