It is rather difficult to find out everything about a person. After all, even about yourself you can not know everything, what can we say about others. How a person can perceive any information, what is in his soul, what skeletons he keeps in the closet - all this is almost impossible to find out. But there are opportunities to learn a lot about a person.
The most accessible information
First of all, you can find out about a person his last name, first name and patronymic, year of birth and place of residence. One conversation is enough for this. You can learn about hobbies and hobbies, about friends and relatives. Such information can be obtained even while in the role of ordinary acquaintances. It is quite easy to find out about the work of an interesting person, what kind of music he likes, what films, what programs. It will also be useful to find it on social networks. All this will help for further investigation, so it is better to record the obtained data somewhere.
Information from sources
Until recently, only law enforcement agencies could receive hidden information, now unlimited access to the Internet allows you to get a lot of information. People spend quite a lot of time on social networks leaving information about themselves. Find the person you are looking for on any social networks and read information about him. It is also worth looking at photographs and videos of the person. From them you can find out about a person's hobbies. Also, scrolling through the wall, you can find a lot of useful information. If possible, it is worth looking at the list of friends, focusing on the most visited. These will most likely be some of your best friends. Try to chat with friends, find out any information. But don't push too hard, ask a lot of questions. Otherwise it will seem like an investigation.
If possible, it is worth contacting the person's neighbors. This is especially true for grandmothers on the bench in front of the house. But here the information may be slightly exaggerated. But you can find out what is happening in a person within the walls of the house.
What can a person tell himself unconsciously?
You can learn about a person's character and manners by facial expressions and gestures. But in order to reliably understand body language, you need to study a lot of literature. But then, when communicating with a person, you can read information on his gestures, as if from an open book. Find out what he doesn't want to talk about, where he's lying, and where he's sincere. As the saying goes, body language can't lie.
Another interesting way is to introduce a person into an extreme situation. Scientists have proven that in a state of stress and shock, a person reveals his true nature. Take him on skydiving, kayaking, or some other extreme trip, and watch his actions, emotions and reactions. During the adrenaline rush, the person will open up completely.
