CORE DEFINITION

McLuhan posits that the form of the medium itself reshapes perception and society; its influence often outweighs the specific content it carries.

SCAFFOLDING EFFECT

Reduce cognitive load

"The medium is the message" is a phrase coined by the Canadian communication theorist Marshall McLuhan and the name of the first chapter in his Understanding Media: The Extensions of Man, published in 1964. McLuhan proposes that a communication medium itself, not the messages it carries, should be the primary focus of study.

The form of the medium itself—rather than the content it carries—is the true 'message' that shapes perception and social structure. A new medium changes the way we perceive the world, organize time and space, and its content is often just a continuation of older media.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

When evaluating new technologies, do not only consider what they 'convey', but also how they 'reshape habits and relationships'. Ask: What behaviors does it encourage, what abilities does it weaken, what sense of time does it change? Use this to judge the hidden costs to the organization.
