Incongruent Stereotype Defense, abbreviated ISD, refers to the continued advantageous or disadvantageous treatment of another (or others), despite being based on stereotypes shown to be incongruent upon being confronted with the nonconforming activities and/or traits of the initial person (or people) being stereotyped.
This important new concept that I here and now integrate into social psychology helps us to understand in part, among other things, how in 2024 (Gregorian calendar) a convicted felon became the president-elect of the United States of America.

Highlights From the ISD Overview
1. Incongruent Stereotype Defense (ISD) is a concept introduced to social psychology by Tarik Karenga on November 17, 2024.
2. ISD "describes a [socio-behavioral] phenomenon where individuals or groups continue to treat others advantageously or disadvantageously based on stereotypes, despite being confronted with evidence (e.g., nonconforming activities or traits) that contradicts those stereotypes."4
3. The novelty of ISD lies in explicitly linking the persistence of stereotyping (e.g., actively doubling down on the stereotype) to treatment outcomes, whether advantageous or disadvantageous despite contradictory evidence, and framing it as a defensive process driven by the motivation to maintain social, cultural, or personal advantages or disadvantages associated with the stereotype being applied. "Doubling down on the stereotype" is the defense mechanism component of the concept.4
4. The Key Elements of ISD:
● Stereotype Incongruence: The stereotype does not align with the observable traits and/or actions of the stereotyped individual or group.4
● Defensive Behavior: Rather than revising beliefs, individuals or systems actively double down on the stereotype in the face of contradictory evidence and continue to act in ways that reinforce the original bias. This is framed as a defense mechanism driven by the underlying motivation to maintain social, cultural, or personal advantages, or disadvantages associated with the stereotype.4
● Advantageous/Disadvantageous Treatment: The outcome is continued biased treatment (advantageous or disadvantageous), either favoring or harming the stereotyped individual or group, despite being based on the incongruent stereotype. The behavioral defense mechanism has become fully visible.4
5. Theoretical Foundations:
● Cognitive Dissonance Theory: A psychological phenomenon whereby “dissonance, that is, the existence of nonfitting relations among cognitions” (i.e., inconsistencies in an individual's beliefs and behaviors) creates psychological discomfort (Festinger, 1957, p. 3). This psychological discomfort leads to activity oriented toward reconciling the inconsistencies to reduce the existing dissonance.4
● Stereotype Maintenance: When an individual encounters a person who violates a stereotype, rather than changing the stereotype he or she often attempts to maintain it through a process called “subtyping” where group members who violate group stereotypes are effectively fenced off “by assuming that they constitute a distinct subtype of the group” (Kunda & Oleson, 1995, p. 565). This allows the original stereotype to be maintained in the face of disconfirmation. Incongruent Stereotype Defense (ISD) extends this by focusing on the treatment outcomes: Continued biased treatment (advantageous or disadvantageous), despite evidence contradicting the underlying stereotype.4
● System Justification Theory: This theory proposes that members of advantaged and even disadvantaged groups assume that “the existing social system is good, fair, legitimate, and right” (Jost & van der Toorn, 2012, p. 315). Moreover, this existing social system, i.e., status quo, is often preserved through the utilization of stereotypes in order to justify social and economic inequalities. Incongruent Stereotype Defense (ISD) adds to this by linking the "behavioral persistence of stereotyping in the face of contradictory evidence" to continued advantageous or disadvantageous stereotype-based treatment.4
