The trust is the security or firm hope Someone has another individual or something. It is also about the presumption of self and the spirit or vigor to act. For example: “This man does not inspire me confidence, I think I will not accept the deal”, "Juan gave her confidence and she betrayed him", "I have the confidence to defeat the rival".

Starting from this meaning we find a series of terms that also use the concept that we are now analyzing. This would be the case, for example, of the expression "abuse of trust." What she wants to express with her is that someone who has been backed up by another person and given credit at all times has taken advantage of that circumstance, consciously or unconsciously, to harm her or make fun of her.
In the same way, we cannot ignore that there is another term that also uses the word that now occupies us. It is a "vote of confidence." With this expression, what we want to make clear is that someone authorizes another person to carry out a specific action.
However, that same expression is used in the political sphere. And it is established with it that, within some legislative chambers, their members give their support and acceptance to the actions that the reigning government is carrying out in a specific area or situation. In the same way, it is also used to refer to when they give authorization to the government entity to undertake certain tasks.
Precisely within the aforementioned political sector, there is also the expression "trust issue". With it, reference is made to a process by which the head of state or the government are analyzed by the rest of the members of the legislative chamber to, by means of a corresponding vote, decide whether or not to continue performing their duties.
Trust refers, on the other hand, to the familiarity in the deal : "You don't need to comb your hair every time I go to your house, we already have enough confidence", “How dare you talk to me that way? I never gave you such confidence. ”.
For the Social psychology and the sociology , trust is a hypothesis which is done on the future behavior of others. It is a belief that estimates that a person Will be able to act in a certain way in the face of a certain situation: "I'm going to tell my father everything, I have confidence that he understands me and helps me".
In this sense, trust can be strengthened or weakened according to the actions of the other person. In the previous example, if the father helps his son, trust will be strengthened; otherwise, trust will be betrayed and, in the future, it is likely that the child will not act in the same way.
Trust implies a suspension, at least temporary, of the uncertainty regarding the actions of others. When someone trusts the other, he thinks he can predict Your actions and behaviors. Trust, therefore, simplifies social relationships.
