Halo Effect01:27

Halo Effect

The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...
The Stanford Prison Experiment03:20

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Theory of Attribution II: Kelley's Covariation Theory

Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus: Comparing...
Blinding01:11

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
Fundamental Attribution Error01:14

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Blind Procedures02:07

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...

Summary

Accountability interventions did not reduce racial performance gaps in a workplace field experiment. Further research is needed to understand when accountability improves diversity outcomes in real organizations.

Area of Science:

  • Organizational Behavior
  • Applied Psychology
  • Human Resources Management

Background:

  • Accountability is frequently proposed to mitigate workplace discrimination.
  • Empirical evidence from field experiments on accountability's effectiveness in reducing discrimination is lacking.

Purpose of the Study:

  • To experimentally test if an accountability intervention reduces performance evaluation disparities between White and racial-minority employees in a real organizational setting.

Main Methods:

  • A preregistered field experiment involving 3,266 managers rating 17,149 employees was conducted.
  • The study measured performance evaluation gaps before and after the accountability intervention.
  • A supplemental online experiment examined the effect of similar language in hypothetical scenarios.

Main Results:

  • No statistically significant reduction in performance evaluation gaps between White and racial-minority employees was observed.
  • Null effects were not attributable to insufficient statistical power or manager inattention.
  • A supplemental experiment indicated that similar accountability language influenced decision-making in hypothetical contexts.

Conclusions:

  • The field experiment found no evidence that the accountability intervention closed racial performance evaluation gaps.
  • A discrepancy exists between findings in hypothetical settings and real organizational contexts.
  • Additional field research and theoretical development are necessary to determine the conditions under which accountability interventions effectively promote diversity.
