It was during the nonviolent blockade of the Seabrook Station Nuclear Power Plant, which involved the arrest of 1,414 individuals (most charges were later dropped),[citation needed] that Moyer recognised the need for social change activists to understand the dynamics behind movement success. In particular, the need to openly address the contradiction that activists often perceive the normal signs of campaign progress as signs of failure.[citation needed]
After the fall of the Berlin wall in 1989, Moyer participated in many workshops in Eastern Europe about nonviolence and social change. In the mid-1980s, he moved to San Francisco, California, where he began to explore Transpersonal psychology and continued his participation in the Friends meeting there. He also developed a workshop called "Creating Peaceful Relationships" based on his realizations regarding dominator cultures.[citation needed]
