A confession is a statement – made by a person or by a group of persons – acknowledging some personal fact that the person (or the group) would ostensibly prefer to keep hidden.
With respect to confessions of wrongdoing, there are several specific kinds of confessions that have significance beyond the social.
A legal confession involves an admission of some wrongdoing that has a legal consequence, while the concept of confession in religion varies widely across various belief systems, and is usually more akin to a ritual by which the person acknowledges thoughts or actions considered sinful or morally wrong within the confines of the confessor’s religion.
Confession often benefits the one who is confessing.
Confessants are more likely to confess when the expected benefits outweigh the marginal costs (when the benefit of the offense to them is high, the cost to the victim is low, and the probability of information leakage is high).
People may undertake social confessions in order to relieve feelings of guilt or to seek forgiveness from a wronged party, but such confessions may also serve to create social bonds between the confessant and the confessor, and may prompt the listener to reply with confessions of their own.
A person may therefore confess wrongdoing to another person as a means of creating such a social bond, or of extracting reciprocal information from the other person.
In U.S. law, a confession must be voluntary in order to be admissible.Confessions (whether forced or otherwise) may feature in formal or informal show trials.In India sections 24 to 30 of Indian Evidence Act, 1872 deals with confession,but the word confession has not been defined in any statute ,but it has been judicially interpreted to mean an admission of all the ingredients of an offence.
It reads: When any fact is deposed to as discovered in consequence of information received from a person accused of any offence, in the custody of a police officer, so much of such information, whether it amounts to a confession or not, as relates distinctly to the fact thereby discovered, may be proved.
