Not only are swipes underused to build consensus, I dont even believe Tinder is the best example. Baby name apps are. A couple download an app, join a meeting room and swipe. Common names appear on a list.
Now imagine that a restaurant picker could determine whether you never want mexican or dont want mexican today.
Swipes are too often thought of as a binary left/right, when really they are more of a radial menu. Swipe left-up could mean not this time. Swipe left-down means never. Swipe straight up to signify something as to come back to. Swiping is easily 4 to 6 to 8 different outputs of vote. The screen should represent a different color for each one until you let go, so you know which option you are releasing on. Things like Maya have had radial menus forever. If you built true swiping radial menus, you can even have a second later of options once the first has been hovered over for a while.
I would not go into radial menu unless it is some kind of specialist app. I would cut it down to left/right up/down - yes tinder is quite binary and does not have "maybe" as an option.
Still you have to build database of choices which will cost quite some money.
Tinder has this upside that their database of choices is building on its own.
Technically tinder is already more than binary, as upswipe is a different form of positive swipe than right swipe. It works there. Theres really no reason that throwing a picture to one of the four corners cant work.
