From childhood, every person knows that it is not worth having any dealings with traitors and unreliable people.
However, American psychologists have made interesting conclusions. It turns out that betrayal does not always lead to a breakdown in trust and in some cases can be justified.
Research on this topic was conducted at the initiative of employees of the University of California, Los Angeles.

The results of the work were published in the scientific journal Evolution and Human Behavior.
Research by scientists
If you imagine that betrayal can bring benefits, then it will not become a reason for the breakdown of relations.
The researchers came to these conclusions while studying public opinion about trust, reputation and attitudes towards betrayal.
It turns out that when evaluating the actions of certain people, many of us proceed from how this fact affected each of us personally.
That is, if your friend or acquaintance has blabbed to you a third person’s secret, then this person becomes something like an informant for you.
The level of trust in a person decreases.
But if the same fact turned out to be useful for you, then it will not affect the level of trust.
Moreover, this effect is observed in all types of relationships, both personal and friendly, as well as professional.
Conclusion
Scientists believe that people in such situations are often guided by personal gain.
Therefore, the attitude towards traitors can be flexible and depend on the circumstances.
