Wigner's Friend
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
An upgraded version of Schrödinger's cat. Wigner's friend observes the cat in the laboratory, and the cat collapses to "alive". But Wigner is outside the laboratory; for Wigner, the entire laboratory (including the friend and the cat) is still in a superposition of "(friend sees alive cat) + (friend sees dead cat)". Until Wigner opens the door and asks the friend. -
SCAFFOLDING EFFECT
Reduce cognitive load
Subjective levels of reality. - It challenges the uniqueness of "objective facts". For team management, frontline employees (the friend) see specific market feedback (collapse), but for the CEO at headquarters (Wigner), the market is still a vague superposition. The higher the decision-making level, the farther from "collapse".
Anchor fast decisions
Thought experiment: A friend measures a quantum state in a closed laboratory, while external Wigner regards it as a superposition, challenging the definition of measurement and objective reality.
