Dietrich's research focuses on the history of peace studies, peace and development, peace and postmodernity, cultures of peace, theories of peace, peace and world system theory, as well as, in his newest works, the contributions of humanistic psychology to peace studies. His best known and often quoted contribution to peace studies is the Call for Many Peaces published in 1998 and republished in 2006. Therein Wolfgang Dietrich dissolves the notion of a homogenous, universal peace in the plurality of the many peaces and thus establishes an approach, which is founded in respect towards the Other, without however deriving thereof the necessity of understanding this Otherness in all its facets or having to share opinions. Peace is thus thought in the sense of "many peaces" as a noun with a plural. He asserts that what peace means differs on closer inspection from culture to culture and the connotations and etymological interpretations of the concept of "peace" do not coincide in different languages, but are an expression of the plurality of worldviews and perceptions of the societies speaking those languages. Thus, peace no longer signifies an arrival in the utopian paradise at the end of all days, but implies a concretely livable societal process of conflict transformation. Since 2008 Dietrich distinguishes between the energetic, moral, modern, post-modern and trans-rational understanding of peace. He advocates the so-called trans-rational approach, which combines the mechanistic understanding of modern peace with those cosmovisions which are energetically oriented towards the establishment and maintaining of harmonious relations between humans, nature and cosmos. From there he derives his culture-sensitive call for an elicitive approach to conflict transformation. Conflict work to him means facilitating the exploration and creation of new options by the conflicting parties instead of prescriptive conflict resolution by external experts. This approach inaugurated by Dietrich is didactically implemented and practically applied at the Innsbruck School of Peace Studies
