When you're setting up an online dating profile, there is one part of it that is more important than anything else: your profile picture. As nice as it would be if we lived in a society that thought the "About Me" section was more important than the evidence of physical attraction, we don't (at least when it comes to first impressions). And so, if you're trying to make a good impression on all of the online suitors out there, you have to pick the right profile picture. Ideally, your profile picture shouldn't only show off how beautiful you are (look at you!)— it should also show off a little bit of your personality while drawing people in. This is a daunting and intimidating task. Luckily, it is also one that researchers have shown a lot of interest in. Since online dating and social media profiles became really popular, scientists and researchers have been doing studies and surveys to find out just what your profile picture is saying to those that are looking.
