Entirely dismissing how important looks, vibes, personality are in relationships. Not even dating -- if someone smells, you're not going to be incentives to make friends with them. This seems to me to just be trodding the same pseudoscientific route as MBTI personality tests, trying to condense a person into a list of multiple choice questions. That will never work. No algorithm can do it. Social interaction is not a solved game.

The point isn't to be a complete solution to social interaction, the point is to provide a significantly better than random sampling and pairing.

You can then still apply your usual filters afterwards, such as smell, looks, vibes.

It's a shame that they deduce your ranking just from the questions. I think the algorithm would be perfect if paired with a manual ranking by the user.

There are obvious deal breakers, and then as you grow older you develop “taste”.

These are well defined criteria which can be queried upon.

However the ranking only works if both sides are honest.

Yes, but someone who looks, vibes and smells right can still be totally wrong for you. I often thought that online dating was inefficient because my eyes, ears and nose can rule out most potential mates without even thinking, but it works the other way too: I've had many partners I've enjoyed being physical with but would never want to settle down and start a family or anything (then again, I'm not a breeder at all, so take that with a pinch of salt). So it's six of one, half a dozen of the other. You need all things to be right, and this surely can only be better than e.g. Tinder, where you see only pictures.
