Actually this made me so fucking mad I had to go look it up.
The statement being made here, and the implication of it (that women who do not wear makeup might be 'psychopaths') is both a steaming pile of bullshit and an actively dangerous idea to be promoting.
She's likely referring to this study published last year in which the relationships between cosmetic use and personality traits were measured in, and I quote:
1,410 Brazilian women (Mage = 29.9, SD = 10.35), who completed online Big Five and Dark Triad personality measures, reported their usual makeup usage habits, and detailed their makeup usage across different social scenarios.
Bold and italic emphasis mine.
To be perfectly clear: 'Psychopath' is not a clinical diagnosis and has not been a clinical diagnosis for 45 years now. People may be diagnosed with 'antisocial personality disorder' but no one is getting formally diagnosed with 'psychopathy' in 2025.
But that doesn't matter because the study isn't even about that!
That's right: The study is not looking at clinical diagnosis at all, the study is not saying "women who are clinically diagnosed with antisocial personality disorder are more likely to forgo wearing makeup than women who have not been diagnosed with antisocial personality disorder" at all.
The study is saying "There is a correlation between reporting as not wearing makeup, and receiving a result on a Big Five or Dark Triad personality test that ranks highly for 'psychopathy'."
Personality tests like Big Five, Dark Triad or the more well-known Myers-Briggs Type Indicator (MBTI) are extremely controversial in psychology on matters of accuracy, ethics and utility. They are regarded by many psychologists as pseudoscience, and they are absolutely not a diagnostic tool.
Debunking out of the way, let's talk about why it's dangerous:
Correlation is not causation. Correlation is not causation.
Even if we assume that the original video maker was actually factually correct, and the statement "Women who are diagnosed with antisocial personality disorder are less likely to wear makeup than women who are not" is categorically true, pushing that viewpoint as the be all and end all is going to get so many other categories of women thrown under a bus.
There are a whole bunch of categories of women who might be less inclined to wear make up that has nothing to do with them having ASPD.
Like.
Butches
Autistic women
Women in poverty
People who are not women but you may mistakenly believe are women based on their appearance such as AFAB trans people incl. nonbinary and gnc folks.
Women with other disabilities that prevent them from wearing makeup on a day to day basis like: Disabilities that inhibit fine motor control; disabilities that impact eyesight; disabilities that impact energy levels; disabilities that impact their ability to hold certain positions like having their hands up to their face
You know. A lot of fucking people.
Also including women who just don't want to wear fucking makeup leave them alone Jesus Christ it's not some kind of secret psychopath conspiracy you utter ghouls
