If you’ve used a dating app, you’ll know the importance of choosing good profile pics. These photos don’t just relay attractiveness; a recent study suggested that 43% of people think they can get a sense of someone’s personality by their picture. You might guess that someone who has included a photo of themselves hiking is an outdoorsy type of person.

In our study, we recruited 1,388 heterosexual American women from 18 to 24 years old to take a short anonymous online survey. In the survey, we presented them with photos of one of two young white men in their early 20s either posing alone or with a cat.

We also asked the women if they defined themselves as a “cat person,” “dog person,” “neither,” or “both.” Most of the women found the men holding cats to be less dateable….
