Many people have experienced that when you were doing something casually, a tune suddenly jumped into your head? No, this song is played over and over again, until you find that your movements are already in tune. Congratulations! You've been attacked by the brainwashing divine comedy!

you're not alone in this experience. More than 9% people suffer from this kind of torture at least once a week, and about a quarter of them have this kind of experience several times a day. Things that don't need much attention, such as waiting for the water to boil or waiting for the red light, are more likely to attract the invasion of brainwashing divine comedy.

this phenomenon is one of the great secrets of the brain. Scientists can't fully understand why those tunes stay in our heads so easily.

a psychological view holds that "brainwashing divine comedy" is a psychological image. Such images are either visible, for example, when you close your eyes and imagine a red van, or audible, for example, when you imagine a baby crying or the sizzling of hot oil in a pan.

"Brainwashing Divine Comedy" is a special form of audible images, because their appearance is unconscious. For example, you don't plug your ears and think hard about the song "Little Apple". Of course, or should I say, in theory, you wouldn't. It just barges into the music background in your head and then wanders around like an uninvited guest. "

The Divine Comedy of Brainwashing" is mostly vivid, and they are usually composed of a tone, not a so-called chord. An iconic feature of "Brainwashing Divine Comedy" is that they tend to fall into a cycle and repeat it thousands of times every minute. Remembering is also the mission of those "infinite loops" in brainwashing divine comedy. Those songs that have been played repeatedly recently are more likely to haunt you in your mind.

If repetition is almost a trigger, then maybe we should blame the emergence of "brainwashing divine comedy" on modern technology. In the past hundred years, audio equipment has been popularized at an incredible speed, which has helped people to hear the same music over and over again. Records, tapes, CDs, and those handy MP3 players.

So, is it those technologies that breed all kinds of unique modern experiences, and "Brainwashing Divine Comedy" only appeared in the late 2th century?

This can be answered by Mark Twain. In 1876, just a year before the phonograph was successfully developed, he wrote a short story, imagining a rhythmic jingle taking over the whole town insidiously.

This example, together with other things, shows that "Brainwashing Divine Comedy" is a basic psychological phenomenon, perhaps only strengthened by modern recording technology, but it is not a new thing in this century.

So, yes, any great historical figure, from Shakespeare to sacagawea, has also hesitated when the "brainwashing divine comedy" occupied his head.

it's hard to think of anything that invades the brain except music, which has such a wide influence. Why can music do it? Why can't watercolors get stuck in your brain? And those ice cream ice cream?

There is a theory that it has something to do with the way music is expressed in memory. When we are listening to those known songs, we always hear the next note we expect in advance. It is difficult for us to remember only one note. If we want to think about the pitch of "Le" in "Happy Birthday to You", we have to go back from "Zhu" to "Le". In this way, a tune seems to be a "habit". Just like once you start tying your shoelaces, you will unconsciously tie a bow before you stop. Once a word is mentioned, because, for example, someone says "two", and then naturally someone will sing "tiger" along with it, and then it will go on and on.

but most of this is just speculation. The fact is that we still don't know why we are so susceptible to the brainwashing divine comedy. But a better understanding of them will give us important clues about how the human brain works.

Maybe next time we will be trapped by the melody of Sister Fruit and cannot escape, then we will use it as the starting point of the scientific journey to unlock the great mystery about basic understanding. In case of failure, well, just hum along with it. It's still nice anyway, isn't it?
