A survey by an American multinational company looked at social media habits and found that looking as good as possible on Facebook profile pages is the main priority of 56 per cent of Britons, the Daily Mail reported.
More than half Britons admitted they want to be more like their 'social media personas' than their real selves.
Women carefully hand-pick flattering pictures of themselves to post, while men craft their personalities around intelligence and courageous behaviour.
Social media users from the Middle East and the rest of Europe were far more concerned about appearing intelligent when posting online.
Sixty-one per cent of people from these regions said they wanted to seem intellectual when sharing content and views across social media, the survey said.
The most common reason for indulging in such 'social lies' was finding love or friendship, given by 51 per cent of women and 40 per cent of men.
Impressing other people and covering up insecurities also rated highly as reasons, but nearly half (48 per cent) believe posts that are 'just too good to be true' generally are, the survey by Intel found.
Ninety-one per cent agreed that there are some topics which have no place on social websites.
Eighty-five per cent also felt that people share information that's better left unsaid, while over 70 per cent have felt uncomfortable about friends' posts about them.
Swearing topped the annoying habit chart
