Cognitive Load & Chunking

Working memory holds a handful of items; beyond that, people default, skip and err. Chunking helps comprehension; overloading — dense terms, many steps, jargon — suppresses it, and both can be designed.

An everyday example

A 40-page agreement presented at signing, versus a one-page summary of the ten terms that matter.

What it can cost you

Accepting what you could not hold in mind; being simplified into missing what mattered.

Warning signs

  • I skimmed because it was too much.
  • The summary left out the part that mattered.

One thing to do

Insist on a plain summary of the material terms and check it against the full text; never decide on a document you have not chunked.
