Organizational psychology, also called industrial-organizational psychology, applies psychological science to the study of human behavior in work settings. It draws on motivation theory, group dynamics, cognitive science, personality research, and social psychology to understand and improve how individuals and teams function in organizational contexts. The field has generated practical insights with significant implications for how organizations recruit, develop, and retain talent and how they design work environments that support high performance and human flourishing. Job satisfaction, one of the most studied constructs in organizational psychology, refers to people's positive or negative evaluations of their jobs. Research has documented strong associations between job satisfaction and outcomes including turnover, absenteeism, counterproductive work behaviors, and health. Whether job satisfaction causes performance or is itself caused by performance, or both, has been debated, with research finding bidirectional relationships. The nature of work itself, including variety, autonomy, significance, feedback, and completeness, is consistently associated with job satisfaction through the job characteristics model developed by Hackman and Oldham. Leadership has been studied extensively in organizational psychology, generating a large literature on what makes leaders effective and how leadership can be developed. Early trait-based approaches that searched for universal characteristics of effective leaders gave way to situational and contingency approaches that recognized that effective leadership behaviors vary across contexts. Transformational leadership, which involves inspiring followers through vision, intellectual stimulation, and individualized consideration, has accumulated strong evidence for positive effects on follower motivation, satisfaction, and performance. Servant leadership, which emphasizes leaders' orientation toward follower development and organizational mission over personal advancement, has grown in both research attention and practical adoption. Team effectiveness research has generated the GRPI model (goals, roles, processes, and interpersonal relationships), Google's extensive internal research on Project Aristotle, and other frameworks for understanding what makes teams work. Google's research identified psychological safety, discussed elsewhere, as the most important factor distinguishing high-performing from lower-performing teams. Team composition, including cognitive diversity and skill complementarity, task design, and leadership support are additional factors with consistent research support. Organizational culture, defined as the shared values, beliefs, and behavioral norms of an organization, is among the most significant drivers of organizational behavior and is among the most difficult things to change. Research documents that culture shapes what behaviors are reinforced, what decisions are made, and whether organizational members feel safe to raise concerns, innovate, or act on their values. Culture change is possible but requires sustained leadership attention, consistency between stated values and actual practices, and accountability systems that reinforce the desired culture rather than undermining it. Selection and assessment practices for hiring are a significant focus of organizational psychology. Research on the validity of different selection methods, conducted across decades of studies and synthesized in meta-analyses, consistently finds that structured interviews, cognitive ability tests, and work samples are more predictive of job performance than unstructured interviews, which are highly susceptible to interviewer bias and show lower validity despite being extremely widely used. Organizations that adopt more structured and valid selection methods make better hiring decisions and reduce bias, but doing so requires overcoming managers' preference for the intuition-based interviewing that feels more natural. Performance management, including goal setting, feedback, performance appraisal, and coaching, is another central focus of organizational psychology. Research on feedback effectiveness finds that specific, timely, and behavior-focused feedback is most effective, while general or person-focused feedback often undermines performance. Research on performance appraisals finds that they are subject to rater biases, including leniency, halo effects, and recency effects, and that many organizations' appraisal systems do not produce the motivation or development they are designed to achieve. Employee wellbeing has grown as a field within organizational psychology, moving beyond traditional occupational health to encompass broader wellbeing outcomes including flourishing, engagement, and meaning at work. Research documents that wellbeing is associated with productivity, creativity, and organizational citizenship, providing a business case for investment in employee wellbeing alongside the ethical case. But as discussed in the context of workplace mental health, genuine wellbeing requires organizational conditions that support it, not just wellbeing programs delivered to individuals in poor organizational environments.
