Can a high Cognitive Load be positive?

Yes. A higher Cognitive Load is not necessarily a bad thing.

It can simply mean that your current task appears to require more mental effort than usual, for example, when you are solving a difficult problem, learning something new, or working through complex information.

What matters more is how long that level of effort continues and how it relates to your other Advancify indicators and your personal patterns over time.

Cognitive Load is a personalized productivity indicator, not a medical, neurological or psychological measurement. It is intended to help you understand changes in your work patterns, not to label a particular level as inherently good or bad.
