Thanks for sharing these useful signs of a female psychopath. I was surprised that the article you linked to, mentions that in female psychopaths there is a higher tendency towards impulsivity something I wouldn't have guessed. The authors also mention that it's pretty difficult to assess the prevalence of female psychopaths since they are harder to detect.
I think just in terms of movie depictions and TV series, I can immediately bring to mind a few male psychopath characters but not many female ones. I'm not sure why there would be a focus on male psychopaths?
Thanks again for sharing this fascinating post and bringing to our attention the signs of female psychopathy.
