A new study has revealed that slight difference in people's expressions in pictures can lead to develop considerably diverse first impressions of that individual to others.
Alexander Todorov of Princeton University said that the results suggest that impressions from still photos of individuals could be deeply misleading and the pictures posted online can affect people in unexpected and undesired ways causing subtly biased decisions.
What the study has revealed is something that people in the business of image manipulation have known for a long time yet most psychology research treats face images as veridical representations of individuals, he added.
The study also implies that there really isn't a static link between face and personality.
The research is published in Psychological Science, a journal of the Association for Psychological Science.
