What your Tinder profile picture really reveals about you

Daily Mail - Science & tech 

While dating and personal ads have been around for decades, the way we meet the people we date has changed dramatically in the last five years. Dating apps such as Tinder have captured a large portion of the online dating market. These apps, but especially Tinder, have transformed the way we represent ourselves online when we date. Men are likely to signal specific resources or potential for acquiring resources, while women are more likely to signal pro-social behaviours such as benevolence, charitable work or virtue, researchers found. While attractiveness is important, users are actually signalling much more than just stereotypical looks.
