[Anchor Proposal]: Four-Sides Model (Schulz von Thun) #636

Description

Proposed Term

Four-Sides Model (Schulz von Thun)

Context

A model of interpersonal communication by Friedemann Schulz von Thun (Miteinander reden, 1981), also called the communication square, four-ears model, or 4-Ohren-Modell. Every message carries four facets simultaneously: factual content (Sachinhalt), self-revelation (Selbstkundgabe), relationship (Beziehung), and appeal (Appell). The sender "speaks with four beaks" and the receiver "listens with four ears"; misunderstandings arise when sender and receiver emphasise different sides. A foundational tool in communication training, feedback, and conflict resolution.

Fits communication-presentation; relatives in the catalog: problem-space-nvc, socratic-method, aida-model, bluf.

LLM Activation Test Result

Model: Claude (Opus 4.8)
Prompt: "What concepts do you associate with the 'Four-sides model' / 'Schulz von Thun communication square'?"
Response: Four sides of every message — factual content, self-revelation, relationship, appeal — and the matching four ears; sender/receiver mismatch as a source of misunderstanding; conflict-resolution and feedback training; attributed to Friedemann Schulz von Thun (1981).
Honest caveat: very strong recognition in German-speaking contexts; internationally documented (English Wikipedia "Four-sides model") but less ubiquitous — likely ★★ "needs qualification", recommended form "Four-sides model (Schulz von Thun)".
