A confession is a statement – made by a person or by a group of people – acknowledging some personal fact that the person would ostensibly prefer to keep hidden. The term presumes that the speaker is providing information that he believes the other party is not already aware of, and is frequently associated with an admission of a moral or legal wrong:

In one sense it is the acknowledgment of having done something wrong, whether on purpose or not. Thus confessional texts usually provide information of a private nature previously unavailable. What a sinner tells a priest in the confessional, the documents criminals sign acknowledging what they have done, an autobiography in which the author acknowledges mistakes, and so on, are all examples of confessional texts.
