Wonder Twin Powers: 7 Fascinating Things That Make Twins Unique

Bet you didn’t know these cool facts and hidden histories about twins.

If you have a new set of multiples, welcome to a really marvelous journey through the land of child development. Twins get the pleasure and the challenge of growing and learning with a buddy, and watching this relationship unfold will blow your mind on a daily basis.

Here are some surprising facts and obscure histories about twins, everything from the latest research and landmark studies to the weird and almost mystical tales woven about famous and not-so-famous twins.

  1. Twins have an uncanny percentage of ESP or telepathic events. Science has no explanation, but twins report reading each other’s thoughts, having spontaneous responses to stimulus that is affecting the other twin, and even predicting that their double is in danger. A researcher named Guy Lyon Palyfair has written extensively on twins strange capacity for telepathy here: https://www.amazon.com/Twin-Telepathy-Guy-L-Playfair-ebook/dp/B007SOAYX4?ie=UTF8&btkr=1&ref_=dp-kindle-redirect.
  1. Some twins are mirror images of each other. About 25 percent of identical twins develop directly facing each other, meaning they become exact reflections of one another. For example, one twin may have a birthmark on her left arm, while the other twin has a birthmark on her right, or one twin may be right handed and the other left-handed. In extreme cases, one mirror-image twin’s organs may be reversed, with the heart on the right and liver on the left!
  1. Twins can create their own private language. The scientific term for this is cryptophasia, meaning “secret language,” and researchers estimate that 50% of twins have flexed this special muscle1. We found this phenomenon cool and interesting enough to dedicate an entire blog post to it here: http://www.discobratz.com/blog/double-talk-the-secret-language-of-twins/.
  1. Separated twins sometimes have bizarre identical preferences. It sent a shockwave through the scientific community when a study that traced biological twins who had been separated at birth found that they often did the same job, bought the same brands, and even named their pets the same names. It seems preferences and skills are more in born than we thought2.
  1. Twins tend to be slightly behind the development curve compared with single children. Because they are often low birth weight from having to share resources in the womb, twins can develop a little slower than other children. Pediatricians refer to this as “adjusted age” and inform parents there is not cause for alarm, twins just develop a little differently than singles3.
  1. The number of twins born in the U.S. has skyrocketed. Partly due to in vitro fertility treatments, and partly because of better prenatal care, twins have seen a bumper crop in the last 30 years. In fact, doubles hit an all time high in 2014, constituting 33.9 twins per 1,000 births4.
  1. Identical twins do not have identical brains. Learning shapes the brain anatomically, and so even if the stimulus is the same, or similar, at a very early age, twin brains start to individuate5.


It is an awe-inspiring and intimate look at the marvel of humanity to parent twins. You will watch them grow into their own unique people, but also cultivate a lifelong bond that will at times seem almost super-heroic. The science on this special experience is bounteous.
