I didn't have time to check the original articles, how is "rape" actually defined?
If I have sex with my wife, no consents given either way, is it me raping her? ("penetration")
Would it be me being raped if we have strapon sex?
Apparently, if laws are gender/genitalia neutral, in "both are drunk" or "no explicit concent was given" scenarios sex partners would be both victims and perpetrators.
FBI in 1997
estimated provably wrong rape accusations at 8%.
I would not call it "super rare".
Note that these are not all false accusations, though, as a number of them falls under "not sure" category.
I find it pecular that people look at these stats through the prism of "why would abused people lie ".
Chances of false accusations are related to
how easy it is to set one up, not to actual number of victims.
