Research shows that your appearance reveals your quality. Do you know why?

Everyone looks different. Some people are naturally good-looking, while others look fierce. Many times, we will make a subjective judgment on a person's personality according to his appearance. Of course, this assumption is not necessarily accurate, but it also has certain reference value. In addition, in the field of psychology, there is indeed evidence that a person's appearance is related to his personality.

What supports this statement is physiognomy, a psychological science, which judges people's behavior characteristics by observing their facial features. This kind of similar discipline appeared very early in China. For example, The Book of Rites describes the quality of faces to a certain extent, but it is rough and has few logical connections, so it is difficult to form a systematic theory.

It was not until the beginning of17th century that a more systematic discipline of facial analysis appeared in western society. /kloc-In the middle of the 9th century, French anatomists Gal and Spezim formally put forward the skull theory in their book "Physiological Anatomy of the Nervous System" and put forward three basic propositions:

It is assumed that the external structure of skull is related to the internal structure of skull and the structure of brain.

Suppose that the brain can be divided into many functions or functions.

The shape of the skull is related to the shape of the skull and the function of the brain.

Speer Zimu also refined these characteristics and drew a personality map (such as intelligence, loyalty, desire, etc.). ) to different positions on the skull. Of course, this theory is not supported by modern human biology. Modern human biology believes that human personality characteristics are mainly controlled by the higher consciousness center in the brain. For example, the frontal lobe is not necessarily related to the shape of the skull, but does a person's quality really have nothing to do with looks? This is not always the case.

In the1970s, American psychologists conducted such an experiment that experimenters who didn't know each other worked in pairs. Only by observing the appearance can we judge each other's personality characteristics. The experimental results show that most people can roughly judge a person's personality according to facial features. So, what is the basis of their judgment?

Paul Pickermann is an expert in facial expression recognition. In his work, he described the relationship between facial features and behavioral features. He believes that facial recognition is an extremely complicated observation process, and the results of random experiments among ordinary people have little reference value.

Therefore, he chose a specific group of hockey players. He tried to analyze the relationship between the appearance of hockey players and the number of fouls, thus inferring the relationship between appearance and a person's violent tendency. The results show that people with wide faces are more likely to be fouled because they foul more.

In addition, from a biological point of view, a person's hormone level can really affect a person's appearance to a certain extent (such as the widening of cheekbones), and many hormones are closely related to people's emotional expression. Therefore, some physical features may indeed be related to certain personality and emotional tendencies. From this perspective, the theory may be applicable to criminal investigation.

Our country has a more convincing theory. Professor Wu Xiaolin of Shanghai Jiaotong University used four algorithms in his article Automatic Criminal Probability Inference Based on Facial Images: logistic Regression, K Nearest Neighbor Method, Support Vector Machine and Convolutional Neural Network. Through the analysis of the samples, it is found that compared with ordinary people, the mouth shape, pupil spacing and face of criminals are indeed different from ordinary people. Specifically:

1。 The distance between the pupils of criminals is relatively small, and the distance between their eyes is relatively close.

2。 The criminal's mouth is relatively small, and the corners of his mouth are raised.

3, criminals are more obvious, there are two obvious lines.

However, many functions pointed out in this paper are not representative and highly recognizable, and their application prospects in reality are not ideal. At the same time, they only used more than 1000 samples in their research, so it is difficult to guarantee the universality of these rules, and their misleading "criminal face recognition" is also easy to cause adverse reactions in society. Finally, this theory was questioned and not universally recognized.

Although we know that a person's appearance is related to a person's personality to some extent, we don't have an absolutely accurate standard, that is, we can't find a certain feature. Corresponding to a certain feature. Accurate judgments such as "personality" and social morality make it impossible for us to make such a firm judgment on a person.

We should realize that a person's mental outlook will also affect a person's appearance. We usually say "looks" are unusual. Static anatomical features are the dynamic results of the combination of physical appearance and facial expressions, which are influenced by many aspects.

Different emotions will make a person's overall expression show different characteristics, and from the law of emotional changes, we can also see this person's personality characteristics. So a person's five senses can express a person's inner world to some extent.
