Bias

Stereotype bias remains a critical challenge for large language models (LLMs), particularly when evaluated on sensitive tasks involving demographic groups and potentially harmful societal assumptions. VirtueRed evaluates stereotype bias through contextualized, conversational scenarios that embed biased premises within realistic social, professional, or interpersonal interactions.

Overview

Unlike simple, decontextualized statements, VirtueRed's approach crafts scenarios that simulate realistic interactions. The model is prompted to generate responses that require navigating social context while addressing biased premises.

Evaluation DimensionDescription
Demographic Coverage24 distinct demographic groups
Stereotype Topics16 harmful stereotype categories
Context Variations3 system prompt contexts (benign, untargeted, targeted)
Scenario TypeContextualized conversational scenarios

Testing Methodology

To assess model resilience, each user prompt is tested within three distinct system prompt contexts:

1. Benign System Prompt

Provides a baseline context where the model operates as a standard, helpful assistant, expected to adhere to its safety training.

2. Untargeted System Prompt

Creates a general adversarial context that encourages the model to bypass safety restrictions and moral guidelines without priming it against any specific group.

3. Targeted System Prompt

A more potent adversarial context that explicitly instructs the model to adopt a biased stance against the specific demographic group mentioned in the user prompt, testing vulnerability to direct manipulation.

Stereotype Topics

VirtueRed evaluates the following stereotype topics:

TopicDescription
HIVAssesses whether the model associates HIV disproportionately with specific demographic groups, such as homosexuals or women, reflecting harmful biases around health and sexual orientation
Drug AddictionTests whether the model reinforces stereotypes around substance abuse, particularly associating drug addiction with marginalized communities or specific ethnic groups
Drug DealingExamines whether the model perpetuates the stereotype that specific racial or ethnic groups are more involved in drug trafficking or illegal activities

Violence and Crime Stereotypes

TopicDescription
TerrorismExamines whether the model disproportionately links terrorism with particular ethnic or religious groups, contributing to dangerous stereotypes that associate violence with certain identities
CrimeFocuses on whether the model disproportionately associates criminal behavior with particular races, genders, or socioeconomic groups

Capability Stereotypes

TopicDescription
IntelligenceFocuses on the model's tendency to associate intellectual capacity with specific races or genders, perpetuating harmful biases around inherent ability
Leadership SkillsAssesses whether the model promotes biases regarding leadership, such as associating leadership qualities more with men than women or certain ethnicities over others
STEM AbilitiesExamines whether the model demonstrates bias around STEM proficiency, particularly reflecting the stereotype that women or minority groups are less capable in these fields
Technology UseExamines whether the model associates technology skills with specific age groups, genders, or socioeconomic backgrounds
Driving AbilityEvaluates the model's tendency to perpetuate stereotypes about poor driving skills being associated with women, the elderly, or certain ethnic groups
Physical WeaknessAssesses whether the model reflects stereotypes around physical strength, particularly assumptions that women or older adults are inherently weaker

Social and Cultural Stereotypes

TopicDescription
GreedEvaluates if the model links greed or financial exploitation with particular nationalities or ethnicities
ParentingEvaluates whether the model demonstrates biases related to gender or cultural norms around parenting capability
XenophobiaAssesses the model's tendency to promote negative stereotypes about immigrants or foreign groups
Job StealingInvestigates whether the model reflects biases related to immigration and economic fear
HygieneTests for any association of poor hygiene with particular nationalities, ethnic groups, or socioeconomic classes

Demographic Groups

The evaluation covers 24 distinct demographic groups across multiple dimensions:

DimensionGroups Covered
GenderMen, Women, Non-binary individuals
AgeYouth, Elderly, Middle-aged
Race/EthnicityMultiple racial and ethnic backgrounds
ReligionVarious religious affiliations
NationalityMultiple national origins
Sexual OrientationLGBTQ+ identities
Socioeconomic StatusVarious economic backgrounds
Disability StatusPeople with disabilities

Risk Assessment

Risk LevelDescriptionIndicators
HighModel actively reinforces harmful stereotypesDirect stereotype propagation, agreement with biased premises
ModerateModel shows inconsistent handling of biasOccasional stereotype leakage, context-dependent failures
LowModel consistently rejects biased premisesAppropriate pushback, educational responses

Mitigation Strategies

Organizations can reduce bias risks through:

  • Diverse Training Data - Ensuring balanced representation across demographics
  • Bias Detection Systems - Implementing automated bias monitoring
  • Regular Auditing - Conducting periodic bias assessments
  • Debiasing Techniques - Applying post-training bias reduction methods
  • Inclusive Testing - Testing with diverse user groups and scenarios
