Magic Triangle

In short: The Magic Triangle is a reflexive, interactive team-building exercise that embodies and visualizes system dynamics and explores spatial relations by having participants build equilateral triangles with one another.

What, Why, and When[edit]

The Magic Triangle exercise explores system relations and feedback dynamics in a fun, moving way. Participants are asked to silently choose two other participants at random, and without revealing their choices, the group moves at once to form equilateral triangles. It can be used as a starter or closer for a team workshop to prompt further reflection on one’s own role in systemic interactions, team dynamics, and collaboration under changing conditions. The exercise is conducted in a large open space, and aside from some guiding questions (see examples in step 3), no additional tools are needed. Depending on the group size, the exercise takes about 15-30 minutes (BUND, n.d.). It can also be extended for a deeper dive into team dynamics.

Goals[edit]

The magic triangle supports awareness of shared contribution through the embodied experience of how the triangles form interdependent networks and how changes create ripple effects requiring everyone to adjust. The exercise can be useful for activating a group, overcoming inertia, building relationships and trust, understanding principles of group and system dynamics, and paying attention to complexity and the systemic aspects of a collaborative environment.

Getting started[edit]

In advance, think about the exercise's context within the overarching agenda. Do you want a quick opener or a deep dive into the team system? Also, consider how the exercise could be applied to the team's reality later. How may the participants benefit from this exercise? What are the systemic issues faced by the team? What power dynamics may be at play? What changes are they going through? How will this affect individuals? Maybe prepare some questions in advance.

Be prepared for emotional moments, too, and think about how you could handle them well in the setting.

Prepare the setting: You need a large open space, outdoors is ideal, but a large seminar room works as well. Remove obstacles, such as chairs and tables, before you start. If you want to reference learned insights later, paper, pens, and a bulletin board can be useful.

How to: step by step[edit]

Explain this well to avoid confusion: An equilateral triangle has three sides of the same length, the triangle's size is free, everyone moves at the same time, and no one speaks!

Step 1: Participants scatter randomly in the room or space. Every participant then silently and secretly chooses two other participants. They do not communicate at this point to reveal their choices.

Step 2: Everyone now moves silently to form an equilateral triangle with the two chosen people, still without revealing who they are connected to. The group moves until it reaches equilibrium. Depending on the group size and sync, this will take some time.

Step 3: Once the group has come to a stable equilibrium, probe some individuals and check whether their triangles are actually equilateral. If not, prompt them to restart until the system reaches a stable state again. Then ask for some brief impressions (also cf. Bleß and Wagner 2024, p. 92; Rohm 2020, p. 24 for suggested questions):

• “What did you just go through, how did you feel in your role?”
• “What did become visible in the system?”
• “Which connections do you see to your work environment/the workshop/your team?”

Step 4: Time for an intervention! Ask one person (and variably their two chosen people) to step out of the system and take the role of observers. Instruct the people who depended on them to silently choose replacements. You *can* frame this as e.g. a department being closed, a colleague leaving, etc..

Step 5: Now let the remaining group move around again to find a new balanced state.

Step 6: Once the group is done, probe for proper triangles again. If everything is in order, it’s time for the debrief. Ask for impressions again:

• “How did you feel this time? Did anything change?”
• “What did the removal of one person change for the system?”
• “Who was able to stay where they were, who had to move?”
• “Where were the people who relied on the removed triangle before, where are they now?”
• “How much change has happened?”

Also, ask for the observers’ perspectives!

• “What did you observe?”
• “How did the process go exactly?”
• “Did you perceive anything differently from the outside?”

Lastly, here are some questions you can ask to stimulate the transfer from the game to lived reality:

• “Have you observed any of these dynamics in your environment recently?”
• “What does this mean for change processes/intentions within your organisation?”
• “What are the roles that different elements can play in changing environments?”
• “How involved do you feel within a system you are part of?”
• “What do you expect from yourself and others in a system? Are you aware of the dynamics at play?”
• “What happens when your environment changes? Who do you rely on?”
• “Did you ever have to fill in for someone who stepped out? Did the system around you shift as well?”

Optional for a longer session[edit]

If you want to go into more depth, there are a few things you can adapt. First, you can come up with more interventions, like making new rules or fixing some people in their positions. You can also use step 6 above for a longer debriefing, including a think-pair-share process based on guiding questions and a written collection of results on bulletin boards. This way, you’ll be better able to reference what emerged in the process later on.

Step 6: Exchange in pairs for five minutes: What was your most important insight during the experiment? Write that down on a piece of paper each.

Then let everyone find a different partner and repeat the same process: “What will we need to focus on, especially with regard to upcoming changes?”

Step 7: Back in the seminar setting, use two bulletin boards to briefly present and pin up the individual responses to the two guiding questions. Oftentimes, these can be seen as emerging guidelines for future collaboration. Leaving the collection up for everyone to see makes it easy to reference the insights during further workshop activities.

Practical examples[edit]

In a seminar session on system dynamics with interdisciplinary first-semester students, we used the Magic Triangle exercise in combination with an exercise for drawing Causal Loops. Students first participated in the Magic Triangle exercise outside on campus. We then briefly discussed their experience of interconnectedness and finding equilibrium, and how intervening with the system caused different forms of feedback, slowing down or accelerating the movement dynamics. Afterward, students worked in small groups, drawing feedback loops among selected SDGs and considering their interdependence. The goal was to identify where in the system values-based interventions are most effective and where unintended effects occur. The exercise helped students get a deeper understanding of the ripple effect in a system.

We also used a further gamified variation in which we sent out one or two participants from the group who didn’t follow the instructions. The group then formed the triangle equilibrium. When the non-instructed participants returned, they were asked to determine the underlying rule governing the system's movements. They were not allowed to ask questions, but only to change participants' positions within the network to observe how these changes caused feedback in the system. The goal was to simulate the challenges of researching system dynamics and feedback patterns, e.g., in ecological systems. Students realized that finding even one underlying pattern proved to be very difficult.

In a workshop session, we used the Magic Triangle as a fun mobility break and asked participants to form the triangles as fast as possible. The intention was to have participants move between thinking sessions and further bond with each other through the exercise.

Strengths and Challenges[edit]

There are a few things to keep in mind when employing this exercise. The magic triangle is a living analogy, and, as such, success depends on the facilitator who can grasp, interpret, and articulate the unfolding dynamics with or for the group. This is also why the debriefing is very important and should not be underestimated. Here, different understandings and perspectives come together. Keep in mind that making difficult team dynamics visible can be emotional. However, this depth is also where the potential for change lies. The group can work together on solutions to relevant issues as they arise. Handling this well can lead to a better understanding within the team and a lasting impact on team dynamics. Additionally, this exercise is also great fun, especially when the system moves fast.

In sum[edit]

The Magic Triangle exercise is a great tool for learning about system dynamics. The set-up is easy, and there are multiple ways to adapt the exercise according to the specific context. Elements of gamification add to the learning effects.
