Both men and women have claimed that one of the biggest turn-offs to a person is an overly negative mindset or personality. It makes sense, as nearly everything comes with a Debbie Downer-like attitude. You cannot tell them anything you hope to get a positive reaction about, as they won’t be happy for you. This makes it hard to be friends or romantic partners with people like this as any good news you’re excited about will be met with absolutely zero joy.
We want others to give us joy and positivity back when we tell them exciting things about us. It is part of human interaction, and we all truly need this. That is also why a more positive attitude makes a person more likable. You WANT to tell them happy news because they will give you happiness back. You might even feel comfortable telling them bad news as they will try to spin something positive out of it to make you feel better. Overall, a negative attitude or personality is like a black hole. No one wants to be caught up in that.
