To go “down the rabbit hole” is to be drawn into something disorienting, complicated or bizarre, usually a line of thought, research or curiosity that keeps opening onto further layers the deeper you go. It can describe a conspiracy theory that pulls someone in further and further, an afternoon lost to clicking through unrelated web pages, or a problem that turns out to be far stranger and more tangled than it first appeared. In modern use it has softened somewhat from its original sense of psychedelic strangeness into something closer to simple absorption or distraction, describing anyone who has lost an hour to reading about a topic that had nothing to do with what they started out looking for.
What’s the origin of the phrase ‘down the rabbit hole’?
The phrase as a figure of speech comes directly from Lewis Carroll’s Alice’s Adventures in Wonderland (1865), whose opening chapter is titled “Down the Rabbit-Hole.” In it, Alice chases the White Rabbit into its burrow and tumbles through into the strange, nonsensical world of Wonderland, where ordinary logic no longer applies. That image, of a literal hole in the ground leading to an entirely different and much odder reality, is what gave the expression its figurative life.
The literal term “rabbit hole”, meaning simply an animal’s burrow, is far older than Carroll and has been in use since the seventeenth century. The figurative sense that grew out of his book is much more recent: dictionary editors date it to the mid to late 1930s.
For much of the twentieth century the phrase still carried that original sense of landing somewhere properly strange, where the usual rules had stopped applying. Its modern drift towards plain distraction belongs to the internet age, when following one link after another became the everyday way of getting lost, and the hole in Carroll’s story turned into a fair picture of an evening spent clicking.
