INTRODUCTION

English translation pending.

CORE DEFINITION

Deferred judgment is a foundational rule of brainstorming, first formalised by Alex Osborn, requiring that evaluation be postponed until after the generation phase is complete. The core proposition is that criticism during generation suppresses both the number of ideas and their novelty, because participants self-censor before an unusual thought is fully formed. The key qualification is that deferral is temporary and structural: it applies to a defined divergence phase, and judgment must return during convergence, otherwise the method becomes an excuse for endless unselective output.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Split The Phases: declare explicitly when the group is generating and when it is judging. - Ban Criticism Early: forbid negative evaluation entirely during the generation phase of the session. - Converge Later: apply explicit criteria once the idea pool is complete.

Anchor fast decisions

Producing an unusual idea requires holding a thought that currently looks wrong, and immediate evaluation punishes exactly that state. Deferring judgment removes the social cost of a bad idea, so participants offer more and stranger options. Quantity also helps quality directly, because a larger pool contains more combinations, and some strong ideas appear only after the obvious ones are exhausted.

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'.
