Post-Allport research shows people can hold prejudice without conscious awareness of it

Evidence

However, rather than probing more deeply into the different reasons why people may not have insight into, or even awareness of, their biases, he dismissed this group as “genuine bigots.” … In contrast, research since the publication of The Nature of Prejudice has recognized that people may not only be unaware of the source of their prejudice (Sears) but also may not be conscious that they have prejudiced beliefs and feelings that influence their behavior in significant ways (Fiske, Gaertner & Dovidio, Rudman). Allport did not anticipate nor prepare the field for the significant impact of research on implicit social cognition that has occurred over the past decade for understanding prejudice, stereotyping, and discrimination. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 148
