If you've got one of those faces that naturally looks, well, a little bit mean and glareyeven when you're thinking happy thoughts about rainbows and kittens and stuff, then we are right there with you.

As it turns out, so are these two behaviouralscientists, who have been studying 'resting bitch face' and who have come to a conclusion that there's actually a legitimate reason some of us have it - and it has nothing to do with having a bad attitude.

The good news is that you now have a anexcuse when people accuse you of looking as though you dgaf,as according to their studiesit's down to genetics and naturally occurswhen you are born witha particularcombination of facial characteristics.

The point is that because of genetics, your neutral face may look like it contains a whole lot of attitude while others have a blanker and more inoffensive version of theexpressionless face.

After using some fancy software and the help of Noldus Information Technology to scan 10,000 human faces, the pair came to the conclusion that around 3% of us naturallyhave a neutralfacial expressionthat readsas being tingedmorewith disdain and sadness than the average, despite the face it isn't actually the case at all.

The softwareproves this by reading these people as having twice the scientific level of contempt on their face than the usual, somthing judgedthrough subtle facial markers like a slight curl of a lip, a slight squint of the eyes and a burrowing of the brows.

“FaceReader is not detecting enough contempt to reflect true contempt, because these faces are not actually displaying contempt,” scientist Abbe Macbeth toldThe Washington Post. “It just looks like contempt to the viewer. Thus, it is the perception of that unconscious, subtle contempt expression that defines RBF.”

Interestingly RBF is also found in both men and women, meaning that any assumption that it's a predominately female attribute mustactually be more of a reflection of society's attitudes to women.

"That [smiling] is something that’s expected from women far more than it’s expected from men, and there’s a lot of anecdotal articles and scientific literature on that," scientist Macbeth tells New York Magazine about their findings.

"So RBF isn’t necessarily something that occurs more in women, but we’re more attuned to notice it in women because women have more pressure on them to be happy and smiley and to get along with others."

Interesting, isn't it? Just a thought but it's probably worth considering this next time you read a headline that brands celebs like Kristen Stewart, Anna Wintour and Victoria Beckham as having resting bitch face. *Sasy nail painting emoji*
