Managing diversity and eliminating discrimination are global concerns. While surface-level diversity like gender and race can activate stereotypes, deep-level diversity in values and personality become more important for similarity as people get to know each other. Effective diversity programs teach managers about equal opportunity, value a diverse workforce, and foster personal development acknowledging different perspectives. Learning involves relatively permanent behavior changes from experience using principles of classical conditioning, operant conditioning, and social learning theory including reinforcement schedules and shaping behavior with rewards.
