The science behind your old friend.
Preisach builds on the Preisach model of hysteresis, peer-reviewed mathematics in use since 1935, and on published research into interacting hysterons. Daniel Preisach’s papers extend that work to how people and AI make decisions. Each paper below states clearly what is established science and what is new proposal.
Interacting Hysterons and Threshold Entanglement in Human-AI Reasoning
The founding paper. It argues that people, AI systems and people working with AI make decisions like a population of switches with memory, and that those switches are not independent.
Read the summary →From Independent to Coupled Hysterons: The Preisach Principle
The formal mathematics. It extends the Preisach model in three steps and states clearly which parts are established physics and which are new proposal.
Read the summary →Applying the Preisach Principle: A Field Protocol
A step-by-step method for testing whether a real situation actually fits the Preisach principle, with the tests written down before the answer is known.
Read the summary →Hysteron Coupling: 3 Isolated vs 3 Coupled
One page, one striking number: what happens when three simple switches are allowed to influence each other.
Read the summary →Sticky Switches: Entangled Hysterons, Without the Maths
A picture guide to one idea: some of your calls work like a sticky light switch. Once flipped, they stay put, and what other people say changes how sticky they are.
Read the summary →Tipping Triads: The Two-Triad Example, Without the Maths
Some habits come in threes and hold each other up. Knock one over and the other two tend to follow. A picture guide to the paper's six-habit example.
