It seems as if human beings require just a teeny dose of narcissism more than anything else, as those who took selfies proved to be happier and more assured of themselves overall.

The results coincide with another recent study which showed that receiving personalised comments on pictures and social media posts are good for our emotional wellbeing.

Speaking with Eurekalert about the study, Moira Burke – a research scientist specialising in human-computer interaction – explained that the comments don’t even have to be long, they just have to be tailored to suit the person reading them.

“We're not talking about anything that's particularly labour-intensive,” she said. “This can be a comment that's just a sentence or two.

“The important thing is that someone such as a close friend takes the time to personalize it.

"The content may be uplifting, and the mere act of communication reminds recipients of the meaningful relationships in their lives."
