Industrial and Organizational (I/O) Psychology is a type of science that studies how people behave and interact at work. It looks at how different factors, like the environment, job roles, and company culture, affect how people think and act, both individually and as teams. I/O Psychologists look at all the different parts of the workplace, like who works there and what types of jobs they do, and use their research to make recommendations for improving the work environment. These recommendations could include things like better job training, more effective teamwork, or ways to promote a healthy work-life balance. Overall, I/O Psychologists use their findings to help employers create a better workplace for their employees.
