      Interesting thread on how accurately you can predict someone's gender with their answers to just 20 questions from a personality test. More than you might think, as it turns out.https://twitter.com/AndrewCutler13/status/1075535228792422400 …

      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

      Pretty bad, but ocean items were not made to tell sexes. I bet one can easily get near 100% with 10 well chosen items. (eg crying frequency)

      Sure, I have no doubt that you can get close to 100% if you chose the questions specifically with predicting gender in mind, but in my opinion 65% ain't that bad when you just used 20 questions from a personality test that wasn't designed for that.

      (I mean, at this pace, soon you'll be able to beat 65% just by asking *one* question, i. e. do you vote Republican or Democrat ^_^)

      Okcupid questions were not designed to tell sex but I'm sure one can do better than 65pct using first 20 items, or random set of 20 items.

      Since I ran tried, yes I was right, but not very much so. I got 72% with random forest. Hmm!

          You mean random forest on 20 randomly selected questions from your OkCupid dataset?
