He says there are some links between the 11 genetic markers, called MHC type, and attraction.
"There is some idea that maybe when we mate, we avoid individuals with the same MHC type. It's still very, very, very, very controversial as to whether humans can even do this.
And there's really very little science into whether it would help us predict mates," Nielsen said.
Profiles are concise and settings are also pared down, like with Tinder, but swiping up allows you to scroll through additional photos instead of super-liking someone.
This means that just because someone twitched their thumb up on your photo, you won’t have to see their profile first every time you open the app, even though you swipe left on their profile every time.
The scientists found that women were more attracted to the scent of a man whose genetics were more different than their own.
But Nielsen says that kind of study has never really been repeated successfully.Following Cambridge Analytica, the company added an additional method to create a profile — by adding your phone number.You’ll then be able to upload photos and fill out your profile information the same way you normally would had you signed up through Facebook instead.Creating a fuller picture Pheramor creators say critics are too concerned about the app’s use of pheromones.They note that the app does not only look at genetic information. This information offers a fuller picture of someone’s behavior and interests.However, Nielsen added that research has shown that mice can recognize DNA that is similar to the DNA of their parents.
