The Science Behind: Doppelgangers

According to ancient legends, seeing your doppelganger is actually a bad omen. It is said that if you meet your doppelganger, death may soon follow. So, as cool as it is to see someone who looks exactly like you if you find your doppelganger, RUN FOR YOUR LIFE.

What are doppelgangers? Doppelgänger is German for double-walker. They are a non-biological twin or look-alike—they are not genetically related to you nor do they have any connection to your family history, but their features are similar to yours.

What is the probability of you having a living doppelganger? The chances of an individual looking exactly like someone else in all eight features is very slim; about one in a trillion! So, mathematically speaking, there is definitely a chance, but good luck if you want to find yours!

As I was going through my research materials for this article, I found an article in a blog I read out of curiosity. I found an example that explains my point above very well. The following quote is by Zaria Gorvett (BBC).

"It’s a mathematical certainty, but reversing the problem reveals just how staggeringly long the monkey would have to toil. Ignoring grammar, the monkey has a one in 26 chance of correctly typing the first letter of Macbeth. So far, so good. But already by the second letter, the chance has shrunk to one in 676 (26 x 26) and by the end of the fourth line (22 letters), it’s one in 13 quintillions. When you multiply probabilities together, the chances of something actually happening disappear very, very quickly."

You might have heard somewhere that you have 7 lookalikes.

According to BBC, “Even with 7.4 billion people on the planet, [there is] only a one in 135 chance that there’s a single pair of doppelgangers.” So imagine how unlikely it is to find seven of them! And even though there is such a tiny chance that you’ll find one of your doppelgangers, if you are mathematically lucky enough, you might just find them. However, don’t expect them to look exactly like you, because those odds are too low—one in one trillion.

Until next time, my friends!!!!!!!
