Sometimes we meet people who immediately become interesting to us or those who cause negative emotions in us. Canadian journalist and writer Malcolm Gladwell, author of the bestselling book Blink, explored this phenomenon in his work.

Gladwell noted that the part of the brain responsible for unconscious perception gives us the ability to spontaneously process information. As an example, they are given: meeting with someone, getting a job, and so on.

The latest findings from research from the University of Maryland School of Medicine suggest that spontaneous and instantaneous compatibility reactions have biological roots. For the study, the behavior of mice was studied. The study showed that enzymes found in parts of the brain that regulate mood and motivation determine who mice want to contact and who is unpleasant for them. At the same time, it is noted that individuals similar in genetics prefer interaction with each other to individuals that differ from them.

The researchers argue that the results of this experiment indicate the factors of preference for social communication among human society. This study was published in Nature.

Scientists hope that this study will help advance the treatment of diseases such as schizophrenia and cognitive decline, when social activity decreases or disappears altogether. By doing this, they want to improve the quality of life of people remote from society.
