In that case people would swipe on just the attractive users and on every bio without reading them.
A simple fix would be to only allow users to swipe on 20% of the photos and 20% of the bios.

And everybody else will follow suit once they realize it's an effective strategy. And you'll have a race to bottom.
That being said, it seems silly to try and force people that only care about looks into caring about bios. Who are we to tell them how to select a partner? Maybe they would be most happy with an attractive partner that doesn't share any of their interests. If that's who they want to find, then instead of telling them they're wrong, we should help them do it.
