First impressions, good or bad, are based on facial images and researchers have designed a model to predict which way things will go. The model was used to also reverse the analysis so that facial images could be created that optimized first impressions. The modeling recognized three factors that determined the first impression based on viewing a face.
The research team was led by Tom Hartley and was carried out in the Department of Psychology at the University of York in the United Kingdom. The study report was published in the journal Proceedings of the National Academy of Sciences.
