An icebreaker
A German psychotherapist developed a group method where strangers stand in for a person's family, claiming their placement reveals hidden loyalties and unresolved loss. Researchers say the evidence for it remains thin; professional bodies have criticized his dogmatic style.
Working from the late 1980s onward, he held that a family carries hidden loyalties and unresolved loss across generations, and that staging a client's family with group stand-ins could surface and help resolve those unspoken patterns.
In his entry on the method, he argued that its claims of sensed, cross-generational family patterns lack a scientific basis and rest on the suggestibility of group participants rather than on any demonstrated transfer of family information.
In his own work on inherited family trauma, he credited constellation work as part of what shaped his approach, while developing a separate method of his own for tracing a person's language back to an earlier family event.
