A Mind-Changing Exercise


After reading Naomi Karten's StickyMinds.com article "Thinking Inside the Box," in which she mentioned an experiential exercise she had facilitated, numerous readers contacted her to learn more about conducting such exercises. In this column, Naomi Karten describes one of her favorite team exercises, with details on how to conduct it and what to expect when you do.

One of my favorite exercises is called a PMI, which stands for Plus, Minus, and Interesting. Its objective is to encourage people who strongly favor or oppose a particular idea to consider other perspectives. I found this exercise in Edward de Bono's book de Bono's Thinking Course—a book that's chock full of activities that will help you stretch your thinking and have fun while doing so.

The PMI is a highly effective and elegantly simple three-minute exercise. It entails having teams spend one minute identifying as many pluses, or good points, as they can about a certain idea; then another minute identifying all the minuses, or negative points; and finally a third minute identifying aspects of the idea that are neither positive nor negative—merely interesting.

We may think we already do a good job of considering ideas from multiple perspectives, but de Bono suggests otherwise. His premise is that once we latch onto a particular opinion, we tend to use our ability to think primarily to support and justify that opinion. In doing so, we become closed to opposing viewpoints. Why consider other views after all when we know we're right?

Though we may be close-minded at times, once we become aware of the possibility of an alternative perspective, we have to acknowledge its existence. As de Bono puts it, "Once an idea has been thought and put down under any of the headings, that idea cannot be 'un-thought' and it will come to influence the final decision."

Here's an example of the PMI in action: I was facilitating a session for a group of IT personnel and their customers to help them work together more effectively. One of the concerns my client (the IT director) had expressed was that the customers were relentlessly negative about following IT standards for development and support. I was instructed to "help them see the value of standards." His concern was valid; yet, in interviews I had previously conducted with the IT staff, I'd detected a "standards at all costs" perspective—a viewpoint perhaps as extreme as that of the customers.

To conduct the PMI, I had the group divide into teams of four or five people, with both IT and customer personnel on each team. I described de Bono's ideas about closing ourselves off to opinions we disagree with and emphasized his point that once we think an idea, we can't "un-think" it. I identified IT standards as the focus of the exercise and explained the three one-minute rounds. First, they'd identify all the pluses they could, then all the minuses, then all the interesting points. I told them I'd let them know when each round had ended and when to begin the next round.

Although I didn't label the exercise as a competition, there's something about being divided into teams that causes participants to become competitive. The result was three minutes of a noisy high-energy frenzy as each team raced to come up with longer lists than the other teams.

This exercise may seem overly contrived. It's not. de Bono offers several examples in which people adamantly committed to a particular point of view found themselves reconsidering their perspective as a result of doing a PMI.
