INTRODUCTION

CORE DEFINITION

The friendship paradox is a network result: the average number of friends your friends have exceeds your own, because the people most likely to appear in your friend list are precisely those with many connections. The general form is a sampling bias, in which high-degree nodes are overrepresented in any sample drawn from their neighbors, and its practical reading is that the feeling of being less popular or less successful than one's peers is often a structural artifact rather than a fact about oneself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Catch the comparison: notice the next feeling that everyone is ahead of you. - Ask who is sampled: check whether the comparison set is your own neighbors. - Discount the bias: recompute the comparison against an unbiased set.

Anchor fast decisions

Any sample drawn from the neighbors of nodes in a network over-represents the nodes with the most connections. Your friend list is exactly such a sample, so the average degree of your friends exceeds the network's average, and the comparison your intuition performs is against a biased sample rather than against the population.

Demographic Transition

Demographic transition refers to the phenomenon in which a country or region transitions from a pre-industrial economic system to an industrialized economic system, often accompanied by a transition from high birth and death rates to low birth and death rates. This theory was proposed by American demographer Warren Thompson in 1929, who observed and studied the changes or transitions in birth and death rates in industrialized societies over the past two centuries.
