What Is Industrial and Organizational Psychology?

Industrial and Organizational (I-O) Psychology is a field concerned with the human side of organizations. Over the past century it has provided both a technology for assessing, selecting, and training employees, as well as insights into the best way to lead and manage. A study of I-O psychology will provide an understanding of how people are affected by their work environments, and how to enable employees to reach their full potential.

I-O Psychology As An Exciting Career

I-O Psychology provides a variety of career opportunities at both the master’s degree and PhD levels. Most I-O psychologists are practitioners who help make organizations become more effective and better places for people to work. They work for private industry, government, nonprofit organizations, the military, or as private consultants. Many I-O psychologists become professors who work mostly in psychology departments or colleges of business at colleges and universities. The job market for I-O psychologists has been strong throughout the years, offering many opportunities for I-O psychologists to utilize their skills.

The Enhanced Digital Edition of the Book

The 9th edition, published in summer 2025, is designed from the ground up to be digital. Most students consume course content online, so this textbook contains additional online-only resources to enhance student learning. The online version contains all the content from the traditional paper version, but supplements it with videos, quizzes, and interactive content. It connects the book to Paul’s blog, with each chapter tying three blog articles to the text discussion. Perhaps the biggest impact on I-O psychology since the 8th edition is the rapid adoption of artificial intelligence, and the book discusses AI from a variety of perspectives across the chapters. Important new topics include Decent work, Design science Digital skilling, Disability, Disruptive technology, Intervention studies, Neurodiversity, Psychological safety, Unhelpful help, and Workplace mental health.
