According to a series of studies published in 2006 by Jennifer Bosson, a social psychologist at the University of South Florida, people form friendships more easily with people who hate the same things they do.
That is exactly what ‘Hater’ works on.

‘Hater’, a new dating app, basically brings together people who hate the same things. It is pretty straight. So if you both dislike trekking, Salman Khan, Donald Trump, even somehow the same mutual friend — there are chances of meeting your future soulmate.
I mean, we get it. Tinder dates can be really a drag. You turn up, talk about a plethora of topics, engage in endless small talk and the end result is usually — Meh! But, don’t you think dating can be much more fun if you can both talk about something you passionately hate? Things are looking pretty bright in my eyes, at least!

Brendan Alper, CEO of Hater, told Digital Trends.
What we hate is an important part of who we are, but it’s often swept under the rug in our public persona. We want people to express themselves more honestly. Plus, it’s easy to start a conversation with someone if you know you both hate pickles.
He told The Cut that he stumbled upon the idea for the app while working on a sketch idea after he had quit his job at Goldman Sachs to become a comedy writer. He said,
The more I thought about it, the more I thought, Hey even though this was a funny idea, it actually makes a lot of sense.

The app, which officially launches on February 8 (but is now available in beta for iOS), lets you swipe up if you love a topic (from a roughly 2,000 topics), down if you hate it, right if you like it, and left if you dislike it. If you have no opinion on a particular topic, you may just dismiss that card. Once you’ve done that, the app selects a group of individuals that share hatred on the same topics as you. Pretty simple, isn’t it?
Well, the idea is definitely new but the bigger question is — Would you use the app?
