An example of an analogy used in public science discourse:
"I often think of executive functioning like air traffic control, so in air traffic control they are trying to land the planes, get them to take off, they are trying to make sure they are filtering out distractions themselves, and that's what executive functioning is, it's multitasking, it is planning, it is strategising, that sort of thing."
Dr Jules Montagu (consultant neurologist and author) was talking on an episode of the BBC radio/podcast series 'Dementia: Unexpected Stories of the Mind')
