CIRCE advances the empirical study of human consciousness — with a focus on altered states induced by pharmacological and non-pharmacological techniques.
Providing high-quality reference datasets and best-practice measurement methods for consciousness research.
We are a German non-profit organization dedicated to the interdisciplinary study of human consciousness. Our work spans basic research, open science platforms, and expert advisory services.
Our primary focus is on altered states of consciousness (ASC) induced by various consciousness-modifying techniques (CMT) — from psychedelics to meditation. By systematically curating psychometric data, we support researchers worldwide.
An open science platform providing comprehensive psychometric data on altered states of consciousness, drawn from peer-reviewed publications and updated annually.
A citizen science initiative for the phenomenological study of ASC. Individuals contribute anonymised first-person accounts, building a freely available repository for researchers.
A curated collection of psychometric questionnaires for ASC research. Includes instrument histories, analysis guidance, translations, and validation studies.
We deepen the scientific understanding of ASC by studying subjective characteristics, neural correlates, and underlying mechanisms — informing both basic research and therapeutic applications.
We advise researchers and institutions on ASC study design, psychometric instrument selection, and methodological rigour — through direct consultation, workshops, and lectures.
We maintain transparent, reliable access to psychometric data via systematic literature searches and annual ASDB updates aligned with PRISMA 2020 — a trusted open-science resource.
Scientists, researchers, and builders united by curiosity about the nature of conscious experience.
Questions about our research, collaboration inquiries, or methodological consultations — we're happy to hear from you.
