Summary

This summary is machine-generated.

Resume anonymization for diversity hiring can backfire. Lower social dominance orientation (SDO) individuals may hire fewer underrepresented candidates when using anonymization, potentially reducing diversity outcomes.

Area Of Science

  • Organizational Psychology
  • Social Psychology
  • Diversity and Inclusion Studies

Background

  • Resume anonymization is a common strategy to mitigate bias and enhance diversity in hiring.
  • However, empirical evidence on the effectiveness of anonymization in large-scale settings has yielded mixed results.
  • Individual differences among decision-makers may influence the impact of anonymization policies.

Purpose Of The Study

  • To investigate the role of social dominance orientation (SDO) in moderating the effects of resume anonymization on hiring decisions.
  • To examine whether individuals with varying SDO levels are differentially likely to opt into anonymization procedures.
  • To assess the potential for anonymization policies to inadvertently decrease diversity in candidate selection.

Main Methods

  • Conducted four pre-registered studies with a total of 3,150 participants.
  • Measured participants' social dominance orientation (SDO).
  • Assessed hiring preferences for candidates from underrepresented groups under anonymized and non-anonymized conditions.
  • Examined participants' propensity to opt into anonymization tools.

Main Results

  • Individuals with lower SDO were less likely to hire candidates from underrepresented groups when resumes were anonymized.
  • Individuals with lower SDO were more likely to choose to use anonymization when given the option.
  • Lay beliefs about the positive consequences of anonymization appear to be inaccurate.

Conclusions

  • Opt-in resume anonymization policies may not always increase diversity and can sometimes reduce it, particularly among individuals with lower SDO.
  • The effectiveness of diversity interventions like anonymization depends on the interaction between heterogeneous treatment effects and selection biases.
  • Future policy evaluations should consider individual differences and potential unintended consequences of diversity initiatives.

Stereotypes, Prejudice, and Discrimination 02:55

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Deindividuation 00:57

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

History

In the late 1800s, social psychologist Gustave Le Bon first posited the hypothesis that an individual’s behavior can differ between being in a crowd...

Surveys 02:16

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveys allow researchers to gather data from larger samples than may be afforded by...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Groupthink 01:34

When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...
