Not sure if there is any evidence to back up that claim.

There is plenty of evidence to back up that claim. First off, have you not read the major implications of the totally unjustified McMartin pre-school atrocity of the late 1980s? It's hardly an unknown event:

Further, make a major point to read Debbie Nathan and Michael Snedeker's book Satan's Silence extremely important expose of the satanic ritual abuse hysteria and the "repressed memory syndrome" nonsense that were accepted as unquestionable fact by both the police and the media in the total absence of tangible evidence, and based on bogus testimony from children who were bullied by social workers and cops into saying what they wanted to here:

Well there is no presumption when it comes to children because unless science has got it all wrong they ARE essentially much less mature than adults, particularly below puberty.

Science has gotten it all wrong about many things, including the still-ongoing presumption of inherent adolescent incompetence.
