Training has shown little effectiveness in altering harassing or discriminatory behavior. Limitations of prior intervention efforts may reflect poor conceptualization of the problems involved, poor training intervention design, approaches that engender cynicism, or misunderstanding psychological principles of attitude and behavior change. Interventions should capitalize on behavioral science models and tools at multiple levels from a broad array of disciplines to explain harassment and bias, and then to defeat these behaviors. Measures to ensure fair treatment should focus on leadership socialization, organizational culture and climate, increased professional competence, and integration with organizational approaches to corporate social responsibility and performance.
