I've identified 2 dozen of them, and organized them into what we call Attractive Archtypes. It's simply a matter of presenting what you're about in a cool sounding way.
I scoured the internet for evidence claiming otherwise.
The best I could find was a 2015 academic study, which said "If you can get the potential date to stop and think about your headline message..will increase their liking."I couldn't think of an effective way to check if a dating profile headline was "stop & think" worthy.
An attraction technologist at heart, he travels the world in search of beautiful women, new ways to help men with their online dating, and the perfect single malt whiskey.
Remember the main purpose of the profile pics is to grab someone’s attention.
But I have learned a lot over the years about what makes for a good headline for a dating site. Most dating websites & apps don't use them anymore.
