INTRODUCTION

English translation pending.

CORE DEFINITION

The image is of riverbed stones becoming visible as the water level falls. The core proposition is that in many stalled investigations the problem is not insufficient information but excess interference, so reducing noise reveals the answer more efficiently than adding more data. The key qualification is that the water does not recede by itself: the interference must be identified and actively removed, which requires naming the specific sources of noise before any of them can be eliminated.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Noise inventory: list the interference sources, including irrelevant metrics, emotion, and redundant data. - Sequential removal: clear or isolate them one at a time and observe carefully what actually changes. - Control test: isolate the variables deliberately rather than simply adding more observations.

Anchor fast decisions

Signals compete with noise for the same interpretive attention, so adding data to a noisy situation increases the noise along with the signal. Removing interference raises the ratio without adding anything, which is why the answer becomes visible without new information. The method works because the truth was already present and only obscured.

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'.
