INTRODUCTION

English translation pending.

CORE DEFINITION

The anecdote appears in A New Account of Tales of the World, where the seven-year-old Wang Rong declines to pick fruit from a laden roadside tree, reasoning that a tree beside a busy road would have been stripped if the plums were edible. The core claim is that an apparently free opportunity which nobody has claimed is evidence of a hidden defect rather than of luck. The qualification is that the inference depends on the crowd having both the ability and the incentive to seize the opportunity, so it fails in thin or restricted markets.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Opportunity audit: when a gain looks obvious and unclaimed, search for the defect that explains why. - Crowd inference: read the absence of competitors as information about the asset itself. - Value filter: test free or cheap high-yield offers against the question of why nobody took them.

Anchor fast decisions

In any open market, participants compete away easy gains, so an unexploited opportunity signals a cost that is invisible from the outside. The absence of takers is therefore a public verdict about the asset's quality, reached by many independent observers. Reading that verdict backwards lets you infer the hidden defect without having to discover it yourself, which is why the reasoning is cheap and fast.

Net Promoter Score, NPS

The Net Promoter Score is a market research metric, typically a survey questionnaire that asks respondents to rate the likelihood of recommending a company, product, or service to friends or colleagues. The questionnaire consists of a question and a score. The higher the score chosen by the user, the higher the likelihood of recommendation. The Net Promoter Score was first published in the Harvard Business Review in 2003.

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'.
