      Thread about gender and personality. How separable are men and women based on their answers to the mini-IPIP-20 questionnaire? TLDR: Prediction accuracy goes from 50% -> 65% with 20 questions.pic.twitter.com/VeETziRQR3

      So I tried the OKCupid dataset. I took the first 20 items, i.e. those with most data. These are shown in second pic. Then fit random forest to predict sex (2 options only). It only got to 72% accuracy, against base rate of 58%. Not that impressive.pic.twitter.com/l79wgEKqpd

      Cool! That even includes interest in casual sex, which I thought would be a pretty good indicator.

      Of course, these participants are selected for being on OKCupid, a left-wing dating site, so somewhat range restricted which probably reduces sex differences a bit -- but still. Surprised it's only 72 even with RF. I could try more, but already took me hours to fit this on laptop

          Isn't a dating site very sensitive to response bias? You're answering questions in front of prospective future partners.

          There's also the problem of knowing thyself. I've seen plenty of people claim they're empathetic when they're not, or that they try to avoid drama when they're one of the most drama-ridden people I know, etc.

          Yes, self-reports are always problematic but I'd guess that self-reports on dating sites are especially prone to bias

          I can see the errors working towards providing separation though. If there is a difference between the ideal man and woman than each gender will try and mark those answers. Men might be willing to say they take risks (smoke/drink), while women demure on that.

          Even if it's not respondents are more likely to give responses that would match them with the kind of partner they seek. Those will be different on a site like OkCupid compared to a more hookup oriented site as Tinder.

          Oh, I know that potential mates can see the responses. Was just wondering if I could play with the data.
