Work at the Interdevelopmental Institute is evidence-based throughout, deriving from adult-developmental research since 1975. Specifically, we practice informed by the synthesis of developmental insights accomplished in Otto Laske’s Constructive Developmental Framework (CDF).

To increase our work’s critical realism, since 2020 we have embedded it in R. Bhaskar’s and M. Archer’s Social Ontology, thereby interpreting CDF as a theory of human agency operating in four dimensions: social-emotional, cognitive, psychological, and spiritual. We stay open to new developments in social science and philosophy.

Our work largely consists of mentoring professionals of all colors through supervised practice. The work is multi-disciplinary and has a broad agenda: (1) The Practice of Dialectical Thinking, (2) Evidence-Based Developmental Coaching, (3) Cognitive Team Facilitation (aiming for dynamic collaboration), and (4) Case Study Guidance.

Each of these practices is offered at a beginner’s and advanced level, in workshops comprising up to 10 participants forming a cohort, and working as a team over 30 hours in the form of 20 Zoom sessions. Other arrangements are possible.

We work in organizations and institutions internationally.

Instruction is given internationally, in English, throughout the year. Workshops in German are an option. Feedback can be given in English, German, Dutch, and French. Instruction is graduate and presupposes the self-study of ‘Gateway’, a pdf collection of free teaching materials accrued since 2000.
