"Independent research from around the world suggests the actual rate of false reports lies somewhere between 2 per cent and 8 per cent."

Ummm no, no it does not. The research your writers chose to believe said that. In fact the range of values given by research runs much higher than that. In 1994 a Purdue University study looked at false accusations in a small town in the mid-west. They counted the number of false accusations. To be considered a false accusation the accuser herself had to admit the claim was false. When possible the researchers verified with the accused that the new version of events now matched the accused's version. 109 cases were examined.
Fully 41% of the accusation were found false. The admitted motivations for the false accusations were alibis(50%), revenge(30%) and attention-seeking(20%).

The above is a paraphrase of a much longer discussion. Google is your friend.
