You believe thousands of things.
How many have you tested?
An interactive journey through science, logic, perception, intuition, evidence and the architecture of truth. Not a course in becoming a machine — a training in discernment for a mind that is emotional, symbolic, embodied and often wrong.
The central idea
Truth does not require the destruction of the irrational mind. It requires learning when to trust intuition, when to doubt it, and how to test what we think we know.
A dream
may reveal something psychologically important without proving an external event.
An intuition
may generate an excellent hypothesis without proving the hypothesis.
A measurement
may be powerful evidence while still carrying real uncertainty.
EXPERIENCE → INTERPRETATION → HYPOTHESIS → EVIDENCE → CONCLUSION → CONFIDENCE
Chains, not facts
The eyewitness chain
The discovery chain
The mystical chain
The knowledge universe
I — What Is Truth?
Six theories of truth, and why the fight matters
Correspondence, coherence, pragmatic, consensus, constructivist and deflationary accounts — each answering a different question about what 'true' does.
II — The Scientific Method
The full loop: from question to revised theory
Observation, question, hypothesis, prediction, design, controls, measurement, analysis, peer criticism, replication, meta-analysis, revision.
III — Logic & Argument
Validity, soundness, and the fallacy field guide
Deduction, induction, abduction, and the recurring shapes of broken reasoning.
IV — The Biased Brain
Your reasoning has a systematic tilt
Confirmation bias, availability, anchoring, hindsight, Dunning–Kruger, base-rate neglect, survivorship, motivated reasoning.
