INTRODUCTION

English translation pending.

CORE DEFINITION

Developed by Robert Keohane and Joseph Nye, the concept describes international relations characterized by multiple channels of connection, including firms, nongovernmental organizations, and social groups; the absence of a clear hierarchy among issues; and the reduced usefulness of military force. The core claim is that dense ties change how influence is exercised. The qualification is that the model describes a condition rather than replacing realism entirely, since force still matters in some domains.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Layer Mapping: Identify every channel through which two parties are connected, not only the formal one. - Use Untangling Cost: Measure how expensive separation would be across technology, people, data, and capital. - Use Interdependence Design: Bind partners across many layers so no single agreement carries the whole relationship.

Anchor fast decisions

When parties are connected through many channels, each tie creates dependencies that raise the cost of separation, and no single relationship can be severed without disrupting the others. Influence therefore flows through whichever channel is most needed rather than through the strongest party's preferred instrument. The density of ties substitutes for hierarchy as the mechanism that holds the relationship together.

QWERTY Effect

The QWERTY effect is a proposed psycholinguistic phenomenon in which the location of letters on a QWERTY keyboard is statistically associated with the perceived emotional meaning, or valence, of the words containing those letters. In its original formulation, words containing relatively more letters…

Thucydides Trap

The Thucydides Trap is a term coined by American political scientist Graham Tillett Allison, Jr. to describe the potential for direct military conflict when a rising power threatens to displace an existing great power. The term gained rapid popularity in 2015 and is frequently used in analyses of US-China relations.

Dvorak Principle

The Dvorak keyboard layout is far more efficient than QWERTY (reducing finger travel distance by about three times), yet because QWERTY has formed an ecosystem monopoly, the superior Dvorak has never been able to gain widespread adoption.
