We found that there are only 25 places we can go on regularly and old favorites are deleted as new favorites increase

by Rist Art

People constantly search for favorite places such as new homes, new restaurants, new bars, but it turned out that the number of places visited regularly at one point is always kept to "25 places". When "new place" enters the list, it seems that it is a mechanism to delete the place that you have been visiting from the list.

In a study published at Nature Human Behavior, researchers analyzed the behavior of 40,000 people collected from four data sets. Laura Alessandretti and Andrea Baronchelli who are researchers of Applied Mathematics at the University College London who studied at the University College of London are Sen Lehmann who studies the relationship between physics, sociology and computer science at the Technical University of Denmark and Mr. Sune Lehmann of Sony Mobile Communications I did a project with researchers.

According to Alessandretti, the original research was to analyze the data set for 1000 college students. As a result of this survey, it was shown that "people are going only to a limited number of places, even if the place of visit changes," he said, "If we target a wider range of subjects, different results will be shown" He predicted that he had data analysis of 40,000 people. However, as a result of investigations, the same results were shown for the first time even for 40,000 people around the world with different customs and gender.

"People are always balancing between curiosity and laziness." "Think about restaurants and gyms, you will find that we are always accepting one place and throwing away one place. The behavior of such a person led to the unexpected result that "we are always visiting a certain number of places and not always because it is not enough time." "Also, I have found evidence that this research is related to 'the number of social relationships that can be held at one time', but further research is necessary to confirm this point, "Baronchelli says I will. According to previous studies, evolutionary biologist Robin Dunbar says, "For human beings, an average of about 150 people (100 to 230 people) is the cognitive upper limit of the number of individuals who can maintain a stable relationship with each other" I was showing .

"Our research is the first to officially show the link between human mobility and cognition, and by revealing this connection we will be able to design better public spaces and transportation agencies. Ultimately we believe it will encourage all of us to create a more sustainable and healthy urban environment, "Baronchelli said.
