In the modern world, success of corporations is often driven by their employees and teams. Understanding how human behaviors affect the workplace is the main objective of industrial and organizational psychology, also known as I/O psychology. I/O psychologists study factors that promote motivation, team work and productivity, as well as management practices that improve employee’s performance. There are many industrial and organizational psychologists working towards improving working conditions, however, the following 30 people were chosen based on the following criteria:

1. Publications: Majority of the individuals on this list have outstanding publication records. These publications include articles in scientific journals, books and book chapters.

2. Impact on industrial and organizational practices: Although academic research is an important aspect of psychology, its influence can only be assessed once ideas are put into practice and applied in a workplace. Men and women on this list have made a significant impact on modern practices and policies in a workplace.

3. Influence on future research directions: While many researchers have published important papers in the field of industrial and organizational psychology, priority was given to those who have made a substantial change in the way in which certain theories are viewed, or those who have led the way into novel research areas.

4. Awards and recognitions: Most psychologists on this list have been recognized for their achievements by various international professional societies, foundations and even Queen Elizabeth II
