Your level of attractiveness varies depending on who you’re with and how good-looking they are in comparison to you, a small new study shows.

You may think a person’s attractiveness is fixed, but research suggests that context is key when assessing how good-looking someone is. In a cruel, if unsurprising, twist, a person will rank higher on a scale of attractiveness when compared alongside less attractive people than they would when judged alone.

For the study, which was led by psychologists from Royal Holloway, University of London, and published in the journal 40 participants were asked to rate pictures of different faces for their attractiveness.

They were then asked to assess the same faces when they were placed alongside others. When adding these “distractor faces,” the level of attractiveness of the original faces increased from the first round of ranking.
