Warmth Appraisals of warmth have a greater impact on interpersonal and
intergroup relations than appraisals of competence. Warmth is, therefore, the primary dimension within the SCM. Assessments of an out-group or individual's potential threat level predicts the group or person's place along the warmth dimension's high/low spectrum. From an evolutionary perspective, warmth is primary because having a keen understanding of a person's competency is not as relevant if you already know that they are not trying to harm you. Early versions of the SCM predicted that intergroup or interpersonal
competition drove ratings of warmth (low competition → high warmth; high competition → low warmth). In 2015, Kervyn, Fiske, and Yzerbyt expanded the SCM's original definition of threat also include to
symbolic threats, based on Kinder and
Sears (1981)'s
symbolic racism theory, which stems from in-group fears over perceived threats to culture or value norms. In the same paper, Kervyn, Fiske, and Yzerbyt also broadened their concept of warmth and defined it as an umbrella term that encompasses both sociability and morality. This reconceptualization of warmth responded to earlier work by Leach, Ellemers, and Barreto (2007) who argued that the warmth dimension conflated two variables (1) sociability, which describes attributes such as cooperation and kindness, and (2) morality, describing an internal ethical sense. They proposed an alternative three-dimension model, which retained competence and divides warmth into morality and sociability. Their plea for the importance of morality in intergroup perception was also echoed by Brambilla et al. (2011) and Brambilla et al. (2012). In addition to broadening the definition of warmth to include morality, Kervyn, Fiske, and Yzerbyt also countered that early theoretical definitions of warmth had, in fact, included adjectives related to morality even though morality measures were not included when warmth was later operationalized during empirical tests.
Competence People or groups who appear "high in status" are judged as more competent than those with low status. The competence dimension definition and prediction on the basis of status has been robust in the literature, and as such, has not faced the same criticism as the warmth dimension. Durante et al. (2013) cross-cultural review of the literature reported an average correlation between status and competence of
