“Where body language is giving mixed signals (eg. a smile that borders on a grimace or fails to involve the eyes) then the more negative, less socially desirable component is usually the more telling. This is because we are more often motivated to conceal unpleasant truths and anti-social feelings than pleasant, benign ones.”

“Where body language conflicts with the words that are being said, the body language will usually be the more 'truthful' in the sense of revealing true feelings.”

“In almost any aspect of our social lives, the ability to interpret accurately the signals of body language, and to manage the impression we are giving to others, may be critical to our success, or even our survival.”

“The eyes are the most powerful social signalers that we have and hence are sometimes called 'the windows of the soul' One of the key elments of what is called 'social skills training' is getting just the right amount of eye contact. Too little and we come across as shy and awkward; too much and we seem rude.”

“It has been found that people are more sensitive to negative faces, picking sad and angry expressions out of a crowd more quickly than positive ones. This is perhaps because we use them as indicators of threat.”

“Faces may be hard to read because humans are complex social animals that have learned to suppress the display of emotions for various reasons. It is often inappropriate to show negative emotions like hatred and contempt in public, so people go about wearing socially acceptable faces rather like masks.”

“Mirroring the body language of the interviewers may be a way of increasing rapport and making them feel more receptive towards you.”
