A false allegation can occur as the result of intentional lying on the part of the accuser; or unintentionally, due to a confabulation, either arising spontaneously due to mental illness or resulting from deliberate or accidental suggestive questioning, or faulty interviewing techniques. Researchers Poole and Lindsay suggested in 1997 applying separate labels to the two concepts, proposing the term "false allegations" be used specifically when the accuser is aware they are lying, and "false suspicions" (weasel word phrase; dissimulation) for the wider range of false accusations in which suggestive questioning may have been involved.
A false allegation of child sexual abuse is an accusation that a person committed one or more acts of child sexual abuse when in reality there was no perpetration of abuse by the accused person as alleged. Such accusations can be brought by the victim, or by another person on the alleged victim's behalf. Studies of child abuse allegations suggest that the overall rate of false accusation is under 10%, as approximated based on multiple studies. Of the allegations determined to be false, only a small portion originated with the child, the studies showed; most false allegations originated with an adult bringing the accusations on behalf of a child, and of those, a large majority occurred in the context of divorce and child-custody battles.
Research by the Workplace Bullying Institute, suggests that "falsely accused someone of 'errors' not actually made" is the most common of all bullying tactics experienced, in 71 percent of cases.
