All these years we've heard that opposites attract. However, the latest study has discarded this theory and it claims that people often get attracted to people with whom they share similar interests.
This study was published by the American Psychological Association. It was further mentioned in the study that people who have shared interests represent a deeper and more fundamental similarity, called an essence.
The lead author Charles Chu, assistant professor at the Boston University Questrom School of Business, said that we like someone who agrees with us on a political issue, shares our music preferences, or simply laughs at the same thing as us not purely because of those similarities, but because those similarities suggest something more — this person is, in essence, like me, and as such, they share my views of the world at large.
