Index Of Luck By Chance

In the grand narrative of human achievement, luck is often dismissed as the silent passenger—the outlier event that defies explanation. We praise hard work, strategy, and grit, while relegating luck to the footnotes of success or the forefront of failure. However, this perspective ignores the complex mechanics of fortune. To truly understand why events unfold as they do, one must consider the "Index of Luck by Chance": a conceptual framework that measures the interplay between random probability and the circumstances that allow that probability to manifest. It is not merely about being in the right place at the right time; it is about the statistical likelihood of the intersection between opportunity and preparation.

Imagine you have a fair six-sided die. The probability of rolling a six is ( \frac16 \approx 16.67% ). If you roll the die 600 times, the expected number of sixes by pure chance is 100. To truly understand why events unfold as they

Events dominated by skill, where luck only dictates the "margin" of victory.

This paper proposes a mathematical and conceptual "Index of Luck by Chance" (ILC). It aims to differentiate between "Gross Luck"—the raw probability of an event—and "Functional Luck," which accounts for the interplay between environmental entropy and agent-led decision-making. By analyzing variance in controlled environments versus chaotic systems, we establish a metric to determine how much of a specific success can be attributed to pure stochasticity. 1. Introduction

The Index of Luck by Chance is only as good as its inputs. There are three common pitfalls where the index produces nonsense:
