Tinder, whether it originally was intended that way or not, has been designed to promote and reward the most superficial behaviours in the dating world. That's why.
Most dating apps are to a large extent the same. I've been pondering using Hinge lately, which is supposed to be better than most, until I had a chat about it with my flatmate the other day.
Dating multiple people at a time has in many cities apparently become the norm now, which is especially easy for women because of how horny many guys are. It doesn't mean those dates will necessarily be any good of course, which is only
part of the reason why lots of women now do this. I can't be bothered to list the other reasons. I'm growing out of winging about these things.
If you have a problem with how dating apps work, then don't use them. Or at least, have a hard think about what it is you are looking for, set yourself some robust standards and deal breakers, stick to them religiously, and toss the people who don't measure-up to them. I've simplified my deal-breakers a lot:
3.
Not currently in a relationship, open relationship, situantionship, recently broken up or dating multiple people
4.
Not lying or withholding information about any of the above
I value my time, for one, and I'd expect the above list to save me a lot of wasted time going on dates with people who just aren't worth the effort... but that also assumes that they will just compliantly filter themselves out. Most of those questions aren't the typical ice-breakers you would ask on a first or even second date, but it's best to get it out of the way rather than finding out about that sort of crap 3 months in, then trying to backtrack and instead ending up in a 'situantionship' because you no longer like them as much as you thought or wanted to.
The four points above cover all the main bases I can think of, without getting into the minutia of it all. Point 1 covers lifestyle. Point 2 covers financial responsibility. Point 3 covers attachment styles. Point 4 covers personality / trustworthiness. Those 4 points together correlate strongly enough with a multitude of over deal-breakers of mine, that I probably don't even have to bring those up anymore.
