How common are false allegations of child sexual abuse?

Research has shown that false allegations of child sexual abuse by children are rare. Some research has shown the percentages to be as low as one percent. It has been proven that allegations made by child abuse victims compare closely with those of the confessions of pedophiles. Evidence shows that very few children have lied originally. Children have a tendency to minimize and deny abuse and not exaggerate or over-report such reports. Several studies have shown that only a small percentage of child sexual abuse reports are fictitious. Some studies have shown that children understate occurrences of abuse.

Others believe that:

While false (by definition, allegations that are made in bad faith with malice aforethought) allegations of child sexual abuse are uncommon at about 2% - 5%, the numbers of unfounded source misattribution allegations of the same are high. Most of these unfounded (without foundation) allegations are via suggestible children suffering from source/reality monitoring problems and exacerbated by governmental officials who conduct improper forensic child interviews. These officials oftentimes employ a non-NICHD methodology, introducing taint to the interview - e.g. scripting, closed-ended questions, suggestive and leading questions, play therapy (anatomical dolls, puppets and/or drawings), guided imagery, stereotype induction and positive reinforcement.
