That's a really interesting article. The part that most resonated with me came at the end:

  "People can look great on paper but it doesn't mean that they are
  the right person for you.

  "That was basically what came from this whole project - chemistry
  can't be quantified. I have no idea why this guy I am falling for,
  even though he looks terrible on paper and then another guy is
  awesome on paper and I don't care about him at all."

I wish more people tracked the data about their dating experiences and shared their results.
