Love rat's performance and its typical tiger.

Whether a man is scum has nothing to do with whether they are excellent or not, but with their moral bottom line.

They are used to deceiving and manipulating others, do not like to abide by social norms, have no scruples about the safety of others and themselves, are aggressive towards people, are always irresponsible, are good at using sweet words, have no guilt after hurting others, have weak feelings and have no concept of love.

In short, love rat is an antisocial personality, or a disease with "no bad symptoms".

Does that sound terrible? But such people are probably hiding around us. According to a survey of social psychology, they have a mental illness called badness. What is bad? Now let's give you a popular science first.

The disease comes from a book "Be careful, disease is disease" written by Dr. Martha Stott of Harvard Medical School. Illness refers to a person who has no conscience, but it means that this person has an "antisocial personality", which is indeed characterized as mental illness. At the same time, the book reveals a more frightening data: 4% of people in the whole society will have unhealthy symptoms, which means that one in every 25 people around you is what we often say about love rat.

What is conscience?

The word "conscience" first appeared in Mencius, and Zhu's annotation said: conscience is a kind of natural goodness. The so-called heart of benevolence and righteousness. Conscience is an instinctive reaction, and it is a sensory reaction gradually formed after our contact with society. Just like when you see a person fall on the road, you instinctively want to go over and help him up. When you see your friend sad, your first thought is to comfort her.

In addition, conscience also controls our desires and tells us not to do anything wrong. Why don't you fight back when you feel that others have offended you? Why do you like a girl very much and don't pry into the corner? That's because your conscience is telling you that once you do these things, you will be punished and you will feel guilty.
