There is an iconic scene in the cult classic The Matrix that makes for a great metaphor. Morpheus gives Neo a choice between two pills: ‘You take the blue pill and the story ends. You wake up in your bed and believe whatever you want to believe. You take the red pill and you stay in wonderland and I show you how deep the rabbit hole goes.’
