This paper examines the professional and theoretical relationship between industrial and organizational (I/O) psychology and human resources management. Drawing on research by Cascio and Silbey (1979), Murphy et al. (2009), and Prins (2006), the paper argues that human resources depends on I/O psychology for its assessment tools, selection processes, and understanding of organizational culture and group dynamics. It distinguishes the research-oriented role of the I/O psychologist from the applied, people-facing role of the HR professional, while identifying key overlapping competencies including emotional intelligence, cultural literacy, and knowledge of organizational behavior. The paper also reflects on the author's personal career interest in human resources.
Industrial and organizational (I/O) psychology shares much in common with several related fields, and there are multiple professional partnership opportunities. The field most closely linked to industrial and organizational psychology — and one that is important to my personal career development — is human resources. As Cascio and Silbey (1979) point out, assessment centers have transformed the nature of human resources and the candidate selection process, helping organizations make more informed decisions about crafting the ideal organizational culture. Likewise, Murphy, Dzieweczynski, and Yang (2009) show how the field of psychology, and organizational psychology in particular, has contributed to the evolution of assessment measures used at every stage of the human resources process — from initial intake and screening of candidates to ongoing assessments and evaluations. In this sense, human resources depends on organizational and industrial psychology.
The field of industrial and organizational psychology adds complexity to the human resources selection process and also helps human resources managers work with senior management in the creation of a workplace structure and job roles that promote the values and mission of the organization. A psychodynamic approach helps all managers understand the communications and collaborative processes involved in creative thinking and problem solving (Prins, 2006). The main difference between industrial and organizational psychology, on one hand, and human resources, on the other, is that the latter depends on the former but not vice versa. Industrial and organizational psychology is a research-oriented field with broad practical application and the potential for consultation services for businesses. Human resources relies on the principles, theories, and methods articulated in I/O psychology research, and is bolstered by them.
Core competencies and skills in human resources include a fundamental understanding of group dynamics within the organization, the organization's values and mission, and the specific roles and functions of employees. All of these are also core competencies of an applied industrial-organizational psychologist. However, the industrial-organizational psychologist does not necessarily occupy an applied position in the same way that human resources managers do — that is, working directly with staff and administering assessments that psychologists have designed.
