INTRODUCTION

English translation pending.

CORE DEFINITION

Sampling induction is the inferential move from the observed features of a sample to a general claim about the unobserved remainder. It is the backbone of statistical inference and of empirical science. Its core claim is that a properly drawn sample licenses a probabilistic conclusion about the population, with error quantified by the sampling design. The qualification is that the strength of the conclusion rests entirely on representativeness and size: a biased sample supports no valid generalization, and even a good sample yields a claim that can be wrong.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Check the leap: state exactly which population the sample is meant to represent. - Quantify the risk: attach a confidence level and error bound instead of asserting a fact. - Plan for refutation: name the observation that would overturn the generalization before you commit.

Anchor fast decisions

A probability sample gives every member of the population a known chance of selection, so the distribution of sample statistics can be derived in advance. That derivation converts a finite set of observations into an interval estimate with a stated probability of covering the true value. The chain breaks at either end: if selection is not probabilistic, the derivation does not apply, and if the conclusion is stated as certain rather than probable, the interval is discarded. Induction supplies warranted confidence, never proof, which is why falsification remains the corrective.
