It's true. Your introductory psychology textbook is missing a chapter. The one about work.

If you're like most people, you'll spend more of your waking hours working than doing anything else. So the psychology of work and organizations should be in every intro psych textbook, right? But it's not. The Getting I-O into Intro Textbooks (GIT SIOP) Task Force is making progress on this, but the fact remains that most intro psych textbooks lack content on industrial-organizational (I-O) psychology. Fortunately, you've found the missing chapter. It's right here. It's free. It's Creative Commons licensed. It's ready to go.

The Industrial-Organizational Psychology chapter is available in three formats: an illustrated and formatted standalone PDF, a text-only PDF, and a text-only Word document. The Creative Commons license means you can use it as-is, use parts of it, or even adapt it, as long as you give credit and link to the license.

The chapter is also available as a free stand-alone mini-course you can assign to your students. Students receive a completion certificate, which they can present to you for credit. More than 1,200 students from 72 colleges, universities, and high schools have completed the mini-course so far.

You can also find lots of other teaching resources at

If your intro psych course doesn't include material on I-O psych, set aside 30 minutes to read the chapter. If you'd prefer something more interactive, you can take a free mini-course. You might also consider sharing this post (tactfully) with your instructor.

We've been talking to instructors and students for a few years now and we've learned one thing: they want this content. In fact, I-O psychology is one of the fastest growing fields in psychology. Because so few intro psych textbooks have I-O psych content, yours can stand out if you include it.
