An industrial psychologist is a professional who applies psychological principles and research methods to the workplace. They focus on the behavior of employees in the workplace and use their knowledge of human behavior to address challenges such as effective communication, conflict resolution, process evaluation, professional competence, and effective management. The goals of industrial and organizational psychology are to better understand and optimize the effectiveness, health, and well-being of employees in the workplace. Industrial psychologists use quantitative research and evaluation methods to apply best practices within a company and teach people how to work better. They identify training and development needs, design and optimize job and work quality, formulate and implement personnel procedures, and develop criteria for evaluating employee and organizational performance. Industrial psychologists work in a variety of settings, including scientific research and development services, colleges and universities, management, scientific and technical consulting services, private companies and enterprises, and state government. To become an industrial psychologist, one typically needs to earn a bachelors degree in business psychology, although many jobs require a masters or doctoral degree.
