I think general attractiveness and expressions may make a difference, I know it was touched on, but Yasmin’s big smile is a lovely feature. And while Lindsay is pretty, if both had the same shade of skin color you would have to admit that she’s not as beautiful as Yasmin, nor is she smiling so broadly. Kate vs Joanna, similar story, Joanna’s smile is engaging, and it’s difficult to tell how attractive Kate actually is, while Joanna’s facial features are definitely on the very lovely side. How much does this come into play? If Joanna were not so beautiful, I bet her swipe rate would have been lower and her religion more of a deciding factor than it already was. So next question, how much does actual beauty reduce our making logical decisions on who to date? Would we give up personal ideals or concepts of who we should be with when confronted by a disarmingly beautiful potential match?
