This document discusses the use of facial coding and analysis of emotions to gain insights into consumer behavior. It provides information on how 95% of mental activity is subconscious and driven by emotions rather than rational thought. Facial coding is presented as a way to quantify emotions based on techniques developed by Darwin, Ekman and others to analyze facial muscle movements and map them to core emotions. Examples are given of how facial coding has been used to analyze reactions to TV ads and predict sales. The document also discusses using models of human personality traits like the Big Five to develop deeper understandings of consumers and how their traits relate to behaviors, attitudes and values.
