The Cognitive Effort lens analyzes for mental work. It reads how hard the viewer’s brain is working to follow, decode, and reason through the content. Some effort is good, because it means the viewer is engaged. Too much means the content is hard to follow and people give up.

​
What it analyzes for

  • How much active thinking the content demands.
  • The point where a piece becomes too hard to follow.
  • Whether an explanation is clear or overloaded.

​
When to use it

1

Simplifying an explainer

Track Cognitive Effort across an explainer to find the moment it spikes, usually where the message gets too dense and needs simplifying.
2

Pacing a complex pitch

If effort stays high the whole way through, viewers are working too hard. Spread the load or cut the complexity.
3

Checking a deliberately challenging piece

For content meant to make people think, confirm effort rises enough to signal engagement without tipping into confusion.

​
Reading the score

  • High: the content demands a lot of mental work. Engaging in small doses, but a risk of losing people if it stays high.
  • Low: the content is easy to process. Effortless to follow, though it may not be challenging anyone.
