Definition

Fisnow's Theorem holds that people have two ears but only one mouth, which means we should listen at least twice as much as we speak.

Core Idea

We are built to listen more than we speak.
Listening should outweigh talking in proportion.
Good communicators absorb before they broadcast.

How It Works

Two ears and one mouth serve as a reminder of the right ratio.
Listening gathers information, builds trust, and prevents misunderstanding.
Talking too much, by contrast, closes off learning and alienates others.

Usage Example

A manager makes a habit of letting team members fully explain a problem before offering an opinion, and discovers solutions the team already had in mind.

Famous Example

Example: Attributed to L. Fisnow, described as a president and general manager of United Airlines.
Why it fits this rule: The "two ears, one mouth" maxim is the theorem's core image.
Verification status: A management adage; the attribution to a United Airlines executive named Fisnow is commonly repeated but not well documented.

Use Cases / Situations Where It Applies

Listening and leadership communication.
Coaching, feedback, and meetings.
Customer and stakeholder engagement.

When Not to Use or Common Misuse

Do not stay silent when speaking up is required.
Do not treat listening as merely waiting for your turn to talk.
Do not over-apply the ratio mechanically; context sets the balance.
