This article does not, and cannot by its design, say that treatment led to higher recidivism. All it really says is that people high on psychopathy measures might be able to game psychiatrists into believing they are doing better, which is surprising to no one.
If you look at Table 2 this point is clear, those who are high in psychopathy show more recidivism when their percieved treatment change is positive. Those who are low on psychopathy show pretty much no difference between high and low treatment effects. Most likely this just means that those who are planning to reoffend try to game the system to make it seem like they've gotten better.
However, it's unclear how the overall group's recidivism is different compared to those who got no treatment at all because this wasn't measured.
More-or-less, this doesn't support your point.
Lol and just like that you never saw those two again
