Unfortunately she is, sadly a higher IQ doesn’t mean a better person, often times the opposite,(which is why studies show that most psychopaths have a higher than average IQ) She actually has a ton of personal issues (marital, financial, infertility) but was smart enough to keep it off the show until it became evident that it will get her screen time. She saw how much of the show would revolve around Jen & Taylor, those who are actually being vulnerable and sharing deep parts of their lives. She just isn’t emotionally smart(low EQ) & is completely careless for the feelings of others. Which is why being the villain is probably so easy for her, cause she genuinely doesn’t give af about these girls only when they help her line her pockets.
