Many twins have this experience: although they are in different places, their emotional situation is often very similar. Sometimes, even they themselves will doubt whether there is really "telepathy" between them.

In fact, this is only because the climax and trough of their emotional cycle always come at the same time. However, if one of the twins learns that the other is depressed or high, it will usually be quickly recognized by the other emotional contagion.

Jim Lewis and his twin brother Jim springer were born in 1940, but separated after five weeks.

When they met again, people were surprised to find that both brothers were 1.8 meters tall and weighed 82 kilograms. Their skin color, appearance and voice are the same, that is, their standing posture is exactly the same as that of their fork hands. Each of them is surrounded by a circle of white wooden chairs on a big tree trunk in front of the house. Besides, everyone has had vasectomy, and they all have the strange habit of chewing their nails with their teeth.

Thomas bouchard, a psychologist at the University of Minnesota, gave them an intelligence test. In the intelligence test, their thinking ability and reaction are also very similar.

In terms of hobbies, they both like carpentry, don't like studying, like smoking, like racing and don't like baseball. Both of them have suffered from periodic migraine since 10. Pain often lasts 12 hours, and aspirin or other drugs are ineffective.

More interestingly, there are similarities in intelligence factors between siblings of the same parents and between fraternal twins and identical twins. The intellectual similarity between identical twins is the highest, with an average of 25 percentage points higher than that of fraternal twins.

From the existing genetic knowledge, we can know that identical twins are similar in intelligence level, thinking mode and problem-solving steps because of the same genes. When they are faced with the same test environment and test questions, they are likely to choose the same problem-solving methods or even make the same mistakes.

A pair of twin sisters took the big exam, and they had to choose one of the six multiple-choice questions to do when taking the composition exam. The invigilator found that the twin sisters had chosen the same question, so she paid special attention. When they handed in their papers, the invigilator wrote on their papers: "Nancy and Ruth are sitting in two corners of the classroom. They chose the same question and told the same story word for word. "
