Study shows that variations in how people are perceived translate quantitatively into differences in how they are treated
Scientists quantify how we discriminate based on stereotypes - short science news

Stereotypes and discrimination are widespread; however, it is difficult to measure the influence of one’s biases in the way they treat others. To address this, a group of scientists developed a mathematical model able to quantify and predict unequal treatment based on perceptions of warmth and competence. The model was applied in a study that showed that there is a direct, measurable relationship between one’s perceived image and the benefits or rewards that person will receive. “We found that people don’t just see certain groups as warmer or nicer, but if you’re warmer by X unit, you get Y dollars more,” said Ming Hsu, one of the main authors.
