An ongoing investigation into the deepest questions of mind, consciousness, healing and systems. Each week the research engine cross-references the latest work across fields and languages — and shows its work: the sources, a confidence rating, and what would change its mind.
You are more certain of your own selfhood than of almost anything — yet when researchers go looking for the thing that is "you," they keep coming back empty-handed. Five traditions that never spoke to each other all arrive at a self that is processual and relational rather than substantial. Includes a ≈30–45-minute CPD unit.
Read the investigation →We can now measure and manipulate conscious states reliably — and still cannot explain why experience exists at all. The four live theories, a German line most English summaries skip, and why a famous 25-year bet was just conceded. Includes a ≈30–45-minute CPD unit.
Read the investigation →Two theories — active inference and Hoffman's interface theory — agree perception isn't a readout of the world, and disagree sharply on what that means. Includes a ≈45-minute CPD unit.
Read the investigation →Once a month the engine publishes a Proposition: a novel, falsifiable cross-domain hypothesis that connects findings the specialised fields keep separate — with sources, a confidence level, and a falsification test. It's the innovation layer, and it's members-only.
Members also unlock downloadable CPD certificates for the weekly investigations — around 5 hours of certified CPD a month.
Every past investigation and the members-only Propositions live in the archive on Substack — including last month's pieces and their CPD units. Nothing is ever lost.
