ABOUT
What Is the Art of
Collective Integration?
The Art of Collective Integration was originally developed by David Young (楊æ£è³¢) as a trauma-informed practice and framework for transforming fragmentation in human systems into coherence, resilience, and wholeness.
Today, ACI is a training, development and consulting organization. We help individuals, leaders, companies, civic groups and other communities integrate the unspoken and hidden forces that obscure their capacity to relate with those who they believe to be different, wrong, or even dangerous.
Polarization is not a failure of relationship, but a signal that a system's awareness of itself is ready to grow beyond its current capacity.
Our Approach
Polarization arises when unresolved tensions and historical wounds surface in an individual, group, collective, or society. These tensions and wounds show up as topical live wires that create a sense of distance between ourselves and “others.”
​By practicing embodied presence and holding these hidden dynamics with care, we open pathways for authentic relating. Instead of forcing empathy or agreement, this approach emphasizes expanding self-awareness. This allows shared spaces to emerge where diverse experiences, perspectives, and distance can coexist.
​
Drawing from neuroscience, systems work, somatic practices, team development, and collective healing methodologies, ACI helps recognize hidden dynamics, release patterns of contraction, and cultivate the capacities needed to meet today’s complex challenges.
At its core, this art is about restoring relational health and empowering groups to create sustainable solutions together.
Why Should You Participate?
-
Are you avoiding or losing relationships that are challenged by differences of opinion?
-
Do certain topics trigger you and hurt your relationships?
-
Is your community, team or group experiencing relational strain?
-
Do you feel like others are wrong and, therefore, responsible for the level of stress we feel in society?
-
Do you occasionally feel a sense of dread or hopelessness about society?
-
Does it feel like there is no way out of polarization?
The truth is, part of you already knows how to do this. Part of us already knows that we can care for someone with whom we disagree. We know that diverse ideas can help society progress towards greater safety, stability, prosperity and opportunity. ACI’s methodology teaches you how to master this art form.
Join us in one of our events, take the online self-paced mini-course, or join the ACI practice Dojo. Through these programs, you will learn to work with the hidden dynamics that limit your sense of connection, opening the way to greater ease and joy in your relationships.
