INTRODUCTION

English translation pending.

CORE DEFINITION

Idea interbreeding, associated with the writer James Altucher and related to Matt Ridley's account of idea sex, holds that innovation usually consists of combining two existing ideas that have not previously met. The core proposition is that the space of combinations is far larger than the space of individually invented elements, so deliberately forcing unrelated concepts together produces more novelty per unit of effort than attempting to invent from nothing. The key qualification is that combinations must be filtered, since most pairings produce nonsense and selection is what turns generation into innovation.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Collect Raw Material: accumulate concepts from many fields as the raw gene pool. - Force The Pairing: combine two unrelated lists deliberately when you are stuck. - Select The Viable: filter the combinations against a real problem rather than keeping everything.

Anchor fast decisions

Within a field, practitioners share assumptions about what a valid idea looks like, so adjacent concepts get combined repeatedly and the returns diminish. Pairing concepts from distant fields introduces a structure the field has not tried, and because the pairings are cheap to generate, many can be tested. Selection then removes the combinations that cannot work, leaving the small number that are both novel and functional.

A theory introduced by biologist Stuart Kauffman and popularized by Steven Johnson: at any moment, realizable innovations lie only within the one-step-reachable range of current knowledge, resources, and capabilities.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
