A stranger's eye can help you pick best profile picture

When it comes to your profile picture, you may want to let a stranger do the choosing as a recent study has suggested so.

In the first study to investigate the process by which people choose their profile pictures, researchers at UNSW Sydney, Australia found that images selected by strangers convey more favourable first impressions than images people select for themselves.

The findings appear to contradict previous research which showed that people tend to portray themselves more favourably than others.

Lead author David White said: "Our findings suggest that people make poor choices when selecting flattering images of themselves for online profile pictures, which affects other people's perception of them. This effect is likely to have a substantial impact on online interactions, the impressions people form and the decisions they base on them, including whether to employ, date, befriend or even vote for someone."

He added, "Previous work has shown that people make inferences about an individual's character and personality within a split second of seeing a photograph of their face, so our results have clear practical implications; if you want to put your best face forward, it makes sense to ask someone else to choose your picture."

To find out whether selecting one's own profile picture might have a positive or negative effect on first impressions, the researchers asked 102 students to select two out of 12 photos of their own face that they were most or least likely to use as a profile picture in three online network contexts: social networks, dating sites and professional networks.

White noted: "Our results demonstrate that people know how to select profile pictures that fit specific networking contexts and make positive impressions on strangers: dating images appear more attractive, and professional images appear more competent."

However, when the researchers showed these images to unfamiliar viewers (i.e. strangers) they had recruited via the internet and asked them to rate how attractive, trustworthy, dominant, confident or competent the person in them appeared, they found that the images people had selected for themselves made a less favorable impression than images selected by others.

White added: "Future research needs to investigate the mechanisms that underlie the choices people make when selecting profile pictures to find out why people seem to have a limited ability to select the most flattering images of themselves."

The study is published in journal Cognitive Research: Principles and Implications.
