Questions: Workplace Diversity

Question 1

Research on the relationship between team diversity and performance has most consistently found that...

• A. Diverse teams always outperform homogeneous teams
• B. Homogeneous teams always outperform diverse teams
• C. The relationship is moderated by factors such as task type, inclusion practices, and team processes — diversity can help or hinder depending on context
• D. Diversity has no effect on team performance

Answer: (C)

Meta-analyses yield mixed average effects of diversity on performance because diversity operates through competing mechanisms. Information/decision-making benefits (broader perspectives, more alternatives, better error detection) are offset by social categorization costs (in-group/out-group dynamics, communication barriers, reduced cohesion). Which mechanism dominates depends on the task (complex/creative vs. routine), the organizational context (inclusive vs. hostile climate), and team processes (quality of communication, conflict management). There is no universal diversity-performance relationship.

Question 2

Stereotype threat occurs only in formal testing situations and does not affect everyday workplace performance.

• T. True
• F. False

Answer: False

While stereotype threat was first demonstrated in laboratory testing contexts (Steele & Aronson, 1995), research has extended the concept to workplace settings. When members of stereotyped groups are in situations where the stereotype is relevant — a woman in a male-dominated engineering team, an older worker in a technology-focused environment — the threat of confirming the stereotype can impair performance through increased anxiety, reduced working memory capacity, and avoidance of challenging tasks. The effect is situational, not permanent, and can be mitigated by inclusive leadership and organizational practices.

Question 3

What is the distinction between surface-level and deep-level diversity, and why does the distinction matter for understanding diversity's effects over time?

Model answer: Surface-level diversity refers to readily observable characteristics (race, gender, age) while deep-level diversity refers to less visible attributes (values, personality, knowledge, cognitive styles). The distinction matters because surface-level diversity drives initial social categorization effects (in-group/out-group dynamics), but as teams work together over time, deep-level diversity becomes more influential. Teams that navigate initial surface-level tensions can eventually benefit from deep-level cognitive diversity that enhances problem-solving and innovation.

Harrison et al.'s research showed that the negative effects of surface-level diversity on team cohesion diminish over time as members learn about each other's deep-level attributes, while the effects of deep-level diversity on team functioning increase. This suggests that interventions should focus on helping diverse teams get through the initial period where surface-level categorization dominates, so they can reach the stage where deep-level diversity provides information benefits.
