The Society for Industrial Organizational Psychology was established in 1982, and its over 8,000 members are dedicated to applying psychology to people in the workplace. No, they are not "shrinks." Rather, their field of psychology tries to understand and measure human behavior to improve employees' satisfaction in their work, employers' ability to select and promote the best people, and to generally make the workplace better for those who work there. They do this by creating assessments, organizational surveys, training and development courses, and improving selection procedures.

Industrial-organizational (I-O) psychology is the scientific study of the workplace. Rigor and methods of psychology are applied to issues of critical relevance to business, including talent management, coaching, assessment, selection, training, organizational development, performance, and work-life balance - SIOP.com

Industrial and organizational psychologists direct consulting and executive search firms, work for leadership centers, corporations and companies as well as universities. And at this juncture in U.S. economic history, with highly qualified people--from the hourly wage earning ranks to executive boardrooms--being vital to business success, industrial and organizational psychologists are in a position to play major roles in aiding corporations and companies manage their workforces.

I-O practitioners conduct a wide range of research and studies designed to provide information about all phases of the workplace. For example, stigmas in organizations (weight, physical attractiveness, sexual orientation, disability, religious beliefs, race); sexual harassment; the role of personality traits in the hiring process; barriers to successful employment of workers with disabilities; workplace culture, particularly when companies merge; selection of law enforcement officers; reducing absenteeism, workplace aggression; what attracts individuals to certain organizations, and the leadership behaviors of women as leaders are just a few of the studies conducted by I-O psychologists.
