INTRODUCTION

English translation pending.

CORE DEFINITION

The bus ticket theory, proposed by Paul Graham, says that in certain fields the specific knowledge is like collecting discarded bus tickets, worthless as far as anyone can see at the time, and that the people who make the great innovations often hold an irrational, compulsive fascination with exactly those useless details. Its use is interest validation: if your interest in a field is only that it pays, you cannot outwork the person who collects bus tickets out of pure obsession. Find the quirk you would pursue for free.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Check the price you'd work at: notice what you would do even with no pay attached. - Let the quirk live: allow the apparently useless fascination to keep receiving investment. - Connect it to a problem: find the real question your useless knowledge is the answer to.

Anchor fast decisions

Depth is what produces the unique view, and depth is too expensive to buy with money alone, so it is only sustained by an interest that does not depend on reward. The purely curious reach the details the mercenary never will, and the details are where the novel combination is waiting, which is why the obsession and not the discipline is the competitive asset.

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'.
